Lurking in the Shadows: Wide-Separation Gas Giants As Tracers of Planet Formation
Lurking in the Shadows: Wide-Separation Gas Giants as Tracers of Planet Formation Thesis by Marta Levesque Bryan In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California 2018 Defended May 1, 2018 ii © 2018 Marta Levesque Bryan ORCID: [0000-0002-6076-5967] All rights reserved iii ACKNOWLEDGEMENTS First and foremost I would like to thank Heather Knutson, who I had the great privilege of working with as my thesis advisor. 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. -
Thixotropic Phenomena in Water: Quantitative Indicators of Casimir-Magnetic Transformations from Vacuum Oscillations (Virtual Particles)
Entropy 2015, 17, 6200-6212; doi:10.3390/e17096200 OPEN ACCESS entropy ISSN 1099-4300 www.mdpi.com/journal/entropy Concept Paper Thixotropic Phenomena in Water: Quantitative Indicators of Casimir-Magnetic Transformations from Vacuum Oscillations (Virtual Particles) Michael A. Persinger Biomolecular Sciences and Behavioural Neuroscience Programs, Laurentian University, Sudbury, ON P3E 2C6, Canada; E-Mail: [email protected] Academic Editor: Kevin H. Knuth Received: 15 July 2015 / Accepted: 28 August 2015 / Published: 7 September 2015 Abstract: The ~1.5 × 10−20 J which is considered a universal quantity and is associated with the movement of protons in water also relates to the ratio of the magnetic moment of a proton divided by its unit charge, multiplied by viscosity and applied over the O-H distance. There is quantitative evidence that thixotropy, the “spontaneous” increased viscosity in water when undisturbed, originates from the transformation of virtual particles or vacuum oscillations to real states through conversion of Casimir-magnetic energies that involve the frequency of the neutral hydrogen line and the upper bound threshold value for intergalactic magnetic fields. The results indicate that ½ of a single electron orbit is real (particle) and the other ½ is virtual (wave). The matter equivalent per s for virtual-to-real states for electrons in 1 mL of water with a neutral pH is consistent with the numbers of protons (H+) and the measured range of molecules in the coherent domains for both width and duration of growth and is similar to widths of intergalactic dust grains from which planets and stars may condense. The de Broglie momentum for the lower boundary of the width of coherent domains multiplied by the fine structure velocity of an electron is concurrent with the quantum when one proton is being removed from another and when the upper boundary of the rest mass of a photon is transformed by the product of velocities for putative “entanglement” and light. -

The Parallels and Reversals in Chaco, Hubble, and Facebook
YEARNING TO BE THE CENTER OF EVERYTHING WHEN WE ARE THE CENTER OF NOTHING: THE PARALLELS AND REVERSALS IN CHACO, HUBBLE, AND FACEBOOK Barry Vacker and Genevieve Gillespie Forthcoming in: Telematics and Informatics, Special Edition on “The Facebook Phenomenon” AUTHORS Barry Vacker, Ph.D. Associate Professor Department of Broadcast, Telecommunications and Mass Media Temple University 2020 N. 13th St. Philadelphia, PA 19122 Genevieve Gillespie Student Temple University Philadelphia, PA 19122 ABSTRACT Humans have long sought to map their place in the cosmos and then situate their selves at the center of the universe. These patterns are displayed at three radically different sites — the Sun Dagger in Chaco Canyon, the Hubble Space Telescope, and social media and Facebook. Drawing from Marshall McLuhan, this article will theorize the parallels and reversals in these sites, where cosmological discoveries of the expanding universe have been countered by technological innovations involving electronic screens, such that social media counters space telescopes, cyberspace counters outer space, and Facebook counters Hubble. Perhaps the “revolution” of social media merely parallels other cultural reversals, all of which seek to return humans to the center of the universe, when we are the center of nothing. And this desire and delusion to be at the center of everything lies at the heart of contemporary issues facing the global civilization. 1. INTRODUCTION Humans are the only species on Earth to store information outside their bodies — from cave paintings to cinema to cyberspace, petroglyphs to photographs to 3D simulations, books to libraries to the internet. From our minds, we have extended a complex technological system around the planet and into the universe. -
Planets Beyond the Solar System
Understanding exoplanets in the era of large telescopes Yogesh C. Joshi Aryabhatta Research Institute of Observational Sciences (ARIES), India 1 Detection of exoplanets: Transit and Radial Velocity Method When planet passes in front of the stellar disc, it blocks light and we see a dip (loss of flux) in the light curve. 2 ΔF/F0 = (Rp/R*) When planet revolves around the star, the star wobbles and we see a variation in the radial motion.

In terms of size, density and the amount of radiation it receives from its star, this is the most similar planet to the Earth. • TRAPPIST-1f, g and h are far enough from the host star that water could be frozen as ice across their surfaces. If they have thin atmospheres, 5 they would be unlikely to contain heavy molecules of Earth, such as CO2.

Transiting planets around stars are discovered mostly through photometric surveys. Unlike radial velocity surveys, photo- metric surveys do not tend to target slow rotators, inactive or metal-rich stars. Nevertheless, we suspect that observational biases could also impact transiting-planet hosts. Aims. This paper aims to evaluate how selection effects reflect on the evolutionary stage of both a limited sample of transiting-planet host stars (TPH) and a wider sample of planet-hosting stars detected through radial velocity analysis. Then, thanks to uniform deriva- tion of stellar ages, a homogeneous comparison between exoplanet hosts and field star age distributions is developed. Methods. Stellar parameters have been computed through our custom-developed isochrone placement algorithm, according to Padova evolutionary models. The notable aspects of our algorithm include the treatment of element diffusion, activity checks in terms of 0 log RHK and v sin i, and the evaluation of the stellar evolutionary speed in the Hertzsprung-Russel diagram in order to better constrain age. -
50 New Exoplanets Discovered by HARPS 12 September 2011
50 new exoplanets discovered by HARPS 12 September 2011 "The harvest of discoveries from HARPS has exceeded all expectations and includes an exceptionally rich population of super-Earths and Neptune-type planets hosted by stars very similar to our Sun. And even better - the new results show that the pace of discovery is accelerating," says Mayor. In the eight years since it started surveying stars like the Sun using the radial velocity technique HARPS has been used to discover more than 150 new planets. About two thirds of all the known This artist's impression shows the planet orbiting the exoplanets with masses less than that of Neptune Sun-like star HD 85512 in the southern constellation of were discovered by HARPS. These exceptional Vela (The Sail). This planet is one of sixteen super- results are the fruit of several hundred nights of Earths discovered by the HARPS instrument on the HARPS observations. 3.6-metre telescope at ESO’s La Silla Observatory. This planet is about 3.6 times as massive as the Earth and Working with HARPS observations of 376 Sun-like lies at the edge of the habitable zone around the star, stars, astronomers have now also much improved where liquid water, and perhaps even life, could potentially exist. Credit: ESO/M. Kornmesser the estimate of how likely it is that a star like the Sun is host to low-mass planets (as opposed to gaseous giants). They find that about 40% of such stars have at least one planet less massive than Astronomers using ESO's world-leading exoplanet Saturn. -

Astronomers using ESO’s leading exoplanet hunter HARPS have today announced more than fifty New exoplanet animation... newly discovered planets around other stars. Among these are many rocky planets not much heavier than the Earth. One of them in particular orbits within the habitable zone around its star. 00:24 ESOcast intro This is the ESOcast! Cutting-edge science and life behind the scenes of ESO, the European Southern Observatory. 00:44 [Narrator] La Silla observatory 2. In this episode of the ESOcast, we take a close look at another major exoplanet discovery from Footage HARPS ESO’s La Silla Observatory, made thanks to its world-beating planet hunting machine HARPS. 01:02 Footage NTT [Narrator] 3. Among the new planets just announced by Footage HARPS scientists, sixteen are super-Earths — rocky planets up to ten times as massive as Earth. This is the Doppler video largest number of such planets ever announced at one time. A planet in orbit causes its star to regularly move backwards and forwards as seen from Earth. This creates a tiny shift of the star’s spectrum that can be measured with an extremely sensitive spectrograph such as HARPS. 01:35 Zoom (D) [Narrator] In their quest to find a rocky planet that could harbour life, astronomers are now pushing HARPS even further. They have selected ten well-studied nearby stars similar to our Sun. Earlier observations showed that these were ideal stars to examine for even less massive planets.
