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. -

In one myth, Orion boasted he would kill all the wild animals on the earth. But, the earth goddess Gaia, who was the protector of all animals, produced a gigantic scorpion, whose body was so heavily encased that Orion was unable to pierce through the armour, and was himself stung to death. His companion Artemis was greatly saddened and arranged for Orion to be immortalised among the stars. Scorpius, the scorpion, was placed on the opposite side of the sky so that Orion would never be hurt by it again. To this day, Orion is never seen in the sky at the same time as Scorpius.

The Theory of Hurricanes
Annual Reviews www.annualreviews.org/aronline Annu. Rev. Fluid Mech. 1991.23 : 179 96 Copyright © 1991 by Annual Reviews Inc. All rights reserved THE THEORY OF HURRICANES Kerry A. Emanuel Center for Meteorology and Physical Oceanography, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139 KEYWORDS: tropical cyclones, convection,moist convection,finite-amplitude instability INTRODUCTION The hurricane remains one of the outstanding enigmas of fluid dynamics. This is so, in part, because the phenomenonis comparatively difficult to observe and because no laboratory analogue has been discovered. To this it must be added that hurricanes have received surprisingly little attention from the theoretically inclined fluid dynamicist, perhaps owing to an understandable tendency to avoid problems that involve complex thermo- dynamics and lack laboratory analogues. Yet hurricanes involve a rich spectrum of fluid-dynamical processes, including rotating, stratified flow dynamics, boundary layers, convection, and air-sea interaction; as such, they provide a wealth of interesting and consequential research problems. This article reviews recent developments in the theory of hurricanes and delineates the important remaining scientific challenges. THE MATURE HURRICANE: A NATURAL CARNOT ENGINE About 80 rotating circulations knowngenerically as tropical cyclones form over the tropical oceans each year. Of these, roughly 60%reach an intensity (maximumwinds in excess of 32 m s- 1) that qualifies them as hurricanes, a term applied only in the Atlantic and eastern Pacific. (Similar storms in other parts of the world go by different names.) Anexcellent review of the climatology and observed characteristics of these storms is provided by Anthes (1982). Here we use the term hurricane in place of the generic term tropical cyclone. -

For the Thousandth Time, Yes," KQED News, http://blogs.kqed.org/newsfix/2012/05/03/is- climate-change-real-for-the-thousandth-time-yes/) BROOKS: So what are the organizations that say climate change is real? MILLER: Virtually ever major, credible scientific organization in the world. It’s not just the UN’s Intergovernmental Panel on Climate Change. Organizations like the National Academy of Sciences, the American Geophysical Union, the American Association for the Advancement of Science. And that's echoed in most countries around the world. All of the most credible, most prestigious scientific organizations accept the fundamental findings of the IPCC. The last comprehensive report from the IPCC, based on research, came out in 2007. And at that time, they said in this report, which is known as AR-4, that there is "very high confidence" that the net effect of human activities since 1750 has been one of warming. Scientists are very careful, unusually careful, about how they put things. But then they say "very likely," or "very high confidence," they’re talking 90%. BROOKS: So it’s not 100%? MILLER: In the realm of science; there’s virtually never 100% certainty about anything. You know, as someone once pointed out, gravity is a theory. BROOKS: Gravity is testable, though.. -

The Moon Greets the Planets in the November Dawn 4 November 2015, by David Dickinson
The moon greets the planets in the November dawn 4 November 2015, by David Dickinson Watch the scene shift, as the moon joins the dance this weekend. The mornings of Friday, October 6th and Saturday, October 7th are key, as the moon passes just two degrees from the Jupiter and Mars pair and just over one degree from Venus worldwide. Similar close pairings of the moon and Venus adorn many national flags, possibly inspired by a close grouping of Venus and the moon witnessed by skywatchers of yore. Saturday November 7th is also a fine time to try your hand at seeing Venus in the daytime, using the nearby crescent moon as a guide. The moon will be only four days from New, and the pair will be 46 degrees west of the sun, an optimal situation as A tri-planetary grouping from the morning of October Venus just passed greatest western elongation 31st. Credit: Joseph Brimacombe 46.4 degrees west of the sun on October 26th. So did this past weekend's shift back to Standard Time for most of North America throw you for a loop? Coming the day after Halloween, 2015 was the earliest we can now shift back off Daylight Saving Time. Sunday won't fall on November 1st again until 2020. Expect evenings get darker sooner for northern hemisphere residents, while the planetary action remains in the dawn sky. Though Mercury has exited the morning twilight stage, the planets Jupiter, Venus and Mars continue to put on a fine show, joined by the waning crescent moon later this week. -

Optical Counterparts of ROSAT X-Ray Sources in Two Selected Fields at Low
Astronomy & Astrophysics manuscript no. sbg˙comsge˙ed c ESO 2018 October 16, 2018 Optical counterparts of ROSAT X-ray sources in two selected fields at low vs. high Galactic latitudes J. Greiner1, G.A. Richter2 1 Max-Planck-Institut f¨ur extraterrestrische Physik, 85740 Garching, Germany 2 Sternwarte Sonneberg, 96515 Sonneberg, Germany Received 14 October 2013 / Accepted 12 August 2014 ABSTRACT Context. The optical identification of large number of X-ray sources such as those from the ROSAT All-Sky Survey is challenging with conventional spectroscopic follow-up observations. Aims. We investigate two ROSAT All-Sky Survey fields of size 10◦× 10◦ each, one at galactic latitude b = 83◦ (26 Com), the other at b = –5◦ (γ Sge), in order to optically identify the majority of sources. Methods. We used optical variability, among other more standard methods, as a means of identifying a large number of ROSAT All- Sky Survey sources. All objects fainter than about 12 mag and brighter than about 17 mag, in or near the error circle of the ROSAT positions, were tested for optical variability on hundreds of archival plates of the Sonneberg field patrol. Results. The present paper contains probable optical identifications of altogether 256 of the 370 ROSAT sources analysed. In partic- ular, we found 126 AGN (some of them may be misclassified CVs), 17 likely clusters of galaxies, 16 eruptive double stars (mostly CVs), 43 chromospherically active stars, 65 stars brighter than about 13 mag, 7 UV Cet stars, 3 semiregular resp. slow irregular variable stars of late spectral type, 2 DA white dwarfs, 1 Am star, 1 supernova remnant and 1 planetary nebula.
