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. -

News from the High Plains
Department of Physics & Astronomy Greetings Alumni & Friends, February 2014 Physics & Astronomy at 7200’ is alive and kicking. The enclosed plot shows how News from the our student population has seen significant growth over the past decade to a present total of 115, including 38 graduate students (see also the Sputnik-era spike!). This High Plains growth has gone hand-in-hand with the University’s decision to recommit to physics. Our astronomy program now has expertise in star formation, planetary formation, galaxies, quasars, instrumentation, and cosmology. UW physicists work on a wide array of areas in condensed matter physics and biophysics. Much of the focus has been on developing and understanding nanostructures geared toward efficient energy transportation and conversion (e.g., solar cells). Our physics faculty have also been working with the departments of Chemistry, Chemical & Petroleum Engineering, and Mechanical Engineering to develop a cross-college, interdisciplinary Materials Science and Engineering program. This program allows students to take courses from multiple departments, carry out collaborative research, and ultimately pursue a terminal degree in their home departments with a concentration in Materials Science. In terms of infrastructure, our program is almost unrecognizable from where it stood just a few years ago. We now have a first-class nano-fabrication and characterization lab that includes key pieces of equipment such as an electron-beam evaporator, X-ray diffractometer, reactive ion etcher, chemical vapor deposition systems, mask aligner, etc. Our newest faculty member, TeYu Chien, is building up a lab centered around Spring Graduates a state-of-the-art scanning tunneling microscope. Our observatory WIRO is also continuing to see upgrades. -

Hambly Institute for Astronomy, School of Physics, University of Edinburgh, Royal Observatory, Blackford Hill, Edinburgh EH9 3HJ, Scotland, UK [email protected] ABSTRACT We present results of a reconnaissance for stellar companions to all 131 radial- velocity-detected candidate extrasolar planetary systems known as of July 1, arXiv:astro-ph/0603836v1 30 Mar 2006 2005. Common proper motion companions were investigated using the multi- epoch STScI Digitized Sky Surveys, and confirmed by matching the trigonometric parallax distances of the primaries to companion distances estimated photometri- cally. We also attempt to confirm or refute companions listed in the Washington Double Star Catalog, the Catalogs of Nearby Stars Series by Gliese and Jahreiß, in Hipparcos results, and in Duquennoy & Mayor (1991). Our findings indicate that a lower limit of 30 (23%) of the 131 exoplanet systems have stellar companions. We report new stellar companions to HD 38529 and HD 188015, and a new candidate companion to HD 169830. We confirm many previously reported stellar companions, including six stars in five systems, that are recognized for the first time as companions to exoplanet hosts. We have found evidence that 20 entries in the Washington Double Star Catalog –2– are not gravitationally bound companions. -

A Multi-Planet System Transiting the $ V $= 9 Rapidly Rotating F-Star HD
DRAFT VERSION APRIL 25, 2017 Preprint typeset using LATEX style emulateapj v. 12/16/11 A MULTI-PLANET SYSTEM TRANSITING THE V = 9 RAPIDLY ROTATING F-STAR HD 106315 JOSEPH E. RODRIGUEZ1, GEORGE ZHOU1, ANDREW VANDERBURG1,JASON D. EASTMAN1,LAURA KREIDBERG1, PHILLIP A. CARGILE1, ALLYSON BIERYLA1,DAVID W. LATHAM1,JONATHAN IRWIN1, ANDREW W. MAYO1,MICHAEL L. CALKINS1, GILBERT A. ESQUERDO1,JESSICA MINK1 1Harvard-Smithsonian Center for Astrophysics, 60 Garden St, Cambridge, MA 02138, USA Draft version April 25, 2017 ABSTRACT We report the discovery of a multi-planet system orbiting HD 106315, a rapidly rotating mid F-type star, using data from the K2 mission. HD 106315 hosts a 2.51 0.12 R sub-Neptune in a 9.5 day orbit, +0.24 ± ⊕ and a 4.31 0.27 R super-Neptune in a 21 day orbit. The projected rotational velocity of HD 106315 −1 ⊕ (12.9 kms− ) likely precludes precise measurements of the planets’ masses, but could enable a mea- surement of the sky-projected spin-orbit obliquity for the outer planet via Doppler tomography. The eccentricities of both planets were constrained to be consistent with 0, following a global modeling of the system that includes a Gaia distance and dynamical arguments. The HD 106315 system is one of few multi-planet systems hosting a Neptune-sized planet for which orbital obliquity measure- ments are possible, making it an excellent test-case for formation mechanisms of warm-Neptunian systems. The brightness of the host star also makes HD 106315 c a candidate for future transmission spectroscopic follow-up studies. -
