PHYS 133 Academic Honesty Worksheet - Fall 2015 Name: Section: Date: PHYS 133 Academic Honesty Worksheet - Fall 2015 The University of Delaware's Code of Conduct clearly outlines a general expectation for students to act honestly and professionally within the classroom. Plagiarism, fabrication, cheating, or any other forms of academic dishonesty will NOT be tolerated, and students found in violation of the University's code will be penalized and reported through the appropriate channels. A brief description of our expectations pertaining to labs are defined below: Plagiarism: The University's Code of Conduct1 defines plagiarism as \the inclusion of some else's words, ideas, images, or data as one's own," and states that \[w]hen a student submits academic work that includes anothers words, ideas, images, or data...the source of that information must be acknowledged with complete and accurate references and, if verbatim statements are included, with quotation marks as well (Section A.2.a.)." Any graded work that results from shared ideas must give credit to all authors involved. Practically, this means that submitted lab reports should contain the names of all lab partners involved. It also requires that any definitions or ideas borrowed from another source be properly quoted and cited. Fabrication: This is defined by the Code of Conduct to be \the use of information or the falsification of research or other findings (Section A.2.b.)." In lab, this clause prohibits the invention of data or the falsification of results. Forgery of any kind will also not be tolerated. Cheating: The University's Code of Conduct defines cheating in detail, including but not limited to the \copying [of] another's academic work, [or] allowing another person to copy one's own academic work (Section 2.A.c)." In PHYS 133, this means if you work with someone else, you are allowed to submit a joint paper that is the product of both individuals' thoughts and reflections, as long as both authors receive credit. It is also acceptable to discuss ideas as a group. However, work that is required to be submitted individually must be written in your own words, even if you discussed the concepts with a partner. In PHYS 133 Lab, we take academic honesty violations very seriously, including but not limited to: • Copying another student's data, prelab, or lab work • Allowing another student to copy your data, prelab, or lab work • Plagiarism of any form • Fabrication of any kind (this includes forged data) Should your TA and/or your Professor determine that you are in violation of the PHYS 133 cheating policy, you will be subject to the following sanctions, at the discretion of your TA and/or your Professor, that include but are not limited to: • Losing credit for the plagiarized (copied, etc.) part of the assignment • Losing credit for the whole assignment in question • Losing a fraction of your total PHYS 133 lab grade • Receiving penalties issuing from a report made to the University of Delaware's Office of Student Conduct At any point this semester, if you are unsure of how to proceed on an assignment or avoid plagiarism, ask your TAs, and we will be happy to help you. The following exercises are designed to help you learn to recognize and avoid plagiarism, to help you better succeed in the PHYS 133 labs. Complete the rest of this worksheet and return it to your TA in your first scheduled lab session. 1\Student Guide to University Policies : Code of Conduct."

If you think the statement isn't plagiarized, write \ok" in the box below the question; if plagiarized, write \plagiarized" and state why. 1. (2 points) The direct-imaging instrument Gemini Planet Imager (GPI) recently found a baby-Jupiter in a solar system only 100 light-years away. 2. (2 points) The new planet Eridani b may bear similarities to Jupiter, but it certainly isn't an exact copy. As Young writes, \Even through methane is present on Jupiter as well, its detection in 51 Eridani b was a surprise, since previously direct-imaged planets haven't shown clear methane signatures" (Young, par. 6). 3. (2 points) The difference between a cold-start model and a hot-start model is that in the former, \gas giants begin as dense, solid cores that then gather gas around them," while in the latter \planets don't use a rocky seed but begin as instabilities in the star's gaseous protoplanetary disk." 4. (2 points) The dozen or so exoplanets found so far have all been so hot, astronomers have had difficulty developing a definite system for identifying formation mechanisms. 5. (2 points) Caltech's Davy Kirkpatrick states that scientists are unsure of the formation mechanism for the new-found exoplanet (Young, par. 10). 2Young, Monica. \Direct-Image Discovery of a Young Jupiter."

Direct­Image Discovery of a Young Jupiter By: Monica Young | August 17, 2015 The Gemini Planet Imager has discovered its first exoplanet, a young Jupiter still glowing with the heat of its formation. Only 100 light­years away, a just­formed gas giant orbits a Sun­like star, the infant equivalent of Jupiter in the solar system — and the first exoplanet discovery for the direct­imaging instrument Gemini Planet Imager (GPI). The discovery image from Gemini Planet Imager of 51 Eridani b, a gas giant orbiting a star 100 light­years away. Gemini Observatory / J. Rameau / C. Marois GPI is part of the next­gen suite of direct­imaging instruments, which also includes SPHERE, ScEX­AO, and Project 1640. It captures infrared light from stars and their young (less than 1 billion years old) planets. The star­planet contrast is better at infrared wavelengths than in visible light, at least for young systems, since giant planets still glow appreciably with the leftover heat of their formation. GPI operates with a coronagraphic mask, to block most of a star’s light, and silicon microchip deformable http://www.skyandtelescope.com/astronomy-news/direct-image-discovery-of-a-young-jupiter-0817201567/?et_mid=777854&rid=247463745 1/4 8/24/2015 Direct-Image Discovery of a Young Jupiter - Sky & Telescope mirrors, whose shape can bend to cancel out atmospheric turbulence. Some diffracted starlight still leaks through in a speckled pattern, but thanks to the adaptive optics, the instrument can make out planets as long as they are big, young, and hot enough, and far enough from their parent star to escape from its glare. GPI is imaging 600 young, nearby stars in a sweeping search for exoplanets between 2014 and 2016. The discovery of 51 Eridani b came as the team was about 20% of the way through the survey. A Young Jupiter? 51 Eridani b is a gas giant 13 astronomical units from its 20 million­year­old star, which, if it were orbiting our Sun, would put it farther out than Jupiter — somewhere between the orbits of Saturn and Uranus. As directly imaged planets go, this one is relatively cool at 750 Kelvin (900°F). Near­infrared spectra show that this planet’s atmosphere contains methane and water vapor. Even though methane is present on Jupiter as well, its detection in 51 Eridani b was a surprise, since This artist's conception of 51 Eridani b shows the hot layers deep in its atmosphere glowing through the clouds. Because this system is only 20 previously direct­imaged planets million years old, the planet still radiates the heat of its formation. haven’t shown clear methane DanielleFutselaar and Franck Marchis signatures. Though the team obtained two images of the planet, one in December 2014 and one in January 2015, not enough time had elapsed between the two observations to track the planet’s motion around its star. So its mass is still a bit of a mystery. Plugging its temperature into models, Bruce Macintosh (Stanford University and Lawrence Livermore National Laboratory) and colleagues estimate its mass could be anywhere between 2 and 12 Jupiter masses.

Her encouragement, guidance, and perspective helped me navigate many a challenging problem, and my conversations with her were a consistent source of positivity and learning throughout my time at Caltech. I leave graduate school a better scientist and person for having her as a role model. Heather fostered a wonderfully positive and supportive environment for her students, giving us the space to explore and grow - I could not have asked for a better advisor or research experience. I would also like to thank Konstantin Batygin for enthusiastic and illuminating discussions that always left me more excited to explore the result at hand. Thank you as well to Dimitri Mawet for providing both expertise and contagious optimism for some of my latest direct imaging endeavors. Thank you to the rest of my thesis committee, namely Geoff Blake, Evan Kirby, and Chuck Steidel for their support, helpful conversations, and insightful questions. I am grateful to have had the opportunity to collaborate with Brendan Bowler. His talk at Caltech my second year of graduate school introduced me to an unexpected population of massive wide-separation planetary-mass companions, and lead to a long-running collaboration from which several of my thesis projects were born.

Called “Cool Stars, Stellar Systems, and the Sun,” the meeting empha- sized the solar stellar connection and focused discussion on “several topics … in which the similarity is manifest: the structures of chromospheres and coronae, stellar activity, and the phenomena of mass loss,” according to the preface of the resulting, “Special Report of the Smithsonian Astrophysical Observatory.” We could easily have chosen the same topics for this meeting. Over the summer of 1980, the group met again in Bonas, France and then back in Cambridge in 1981. Nearly 40 years on, I am comfortable saying these workshops have evolved to be the premier conference series for cool star research. Cool Stars has been held largely biennially, alternating between North America and Europe. Over that time, the field of stellar astro- physics has been upended several times, first by results from Hubble, then ROSAT, then Keck and other large aperture ground-based adaptive optics telescopes.

It is one of the closest direct imaging planets in angular and physical separation (∼0.500, ∼13 au) and is well suited for spectroscopic analysis using integral field spectrographs. Aims. We aim to refine the atmospheric properties of the known giant planet and to constrain the architecture of the system further by searching for additional companions. Methods. We used the extreme adaptive optics instrument SPHERE at the Very Large Telescope (VLT) to obtain simultaneous dual-band imaging with IRDIS and integral field spectra with IFS, extending the spectral coverage of the planet to the complete Y- to H-band range and providing ad- ditional photometry in the K12-bands (2.11, 2:25 µm).

  • Exoplanet Meteorology: Characterizing the Atmospheres Of
    Exoplanet Meteorology: Characterizing the Atmospheres of Directly Imaged Sub-Stellar Objects by Abhijith Rajan A Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy Approved April 2017 by the Graduate Supervisory Committee: Jennifer Patience, Co-Chair Patrick Young, Co-Chair Paul Scowen Nathaniel Butler Evgenya Shkolnik ARIZONA STATE UNIVERSITY May 2017 ©2017 Abhijith Rajan All Rights Reserved ABSTRACT The field of exoplanet science has matured over the past two decades with over 3500 confirmed exoplanets. However, many fundamental questions regarding the composition, and formation mechanism remain unanswered. Atmospheres are a window into the properties of a planet, and spectroscopic studies can help resolve many of these questions. For the first part of my dissertation, I participated in two studies of the atmospheres of brown dwarfs to search for weather variations. To understand the evolution of weather on brown dwarfs we conducted a multi- epoch study monitoring four cool brown dwarfs to search for photometric variability. These cool brown dwarfs are predicted to have salt and sulfide clouds condensing in their upper atmosphere and we detected one high amplitude variable. Combining observations for all T5 and later brown dwarfs we note a possible correlation between variability and cloud opacity. For the second half of my thesis, I focused on characterizing the atmospheres of directly imaged exoplanets. In the first study Hubble Space Telescope data on HR8799, in wavelengths unobservable from the ground, provide constraints on the presence of clouds in the outer planets. Next, I present research done in collaboration with the Gemini Planet Imager Exoplanet Survey (GPIES) team including an exploration of the instrument contrast against environmental parameters, and an examination of the environment of the planet in the HD 106906 system.
