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. -

Dr. Ron Marzke, Ph.D. Astronomy Assoc. Dean of College of Science & Engineering A SEARCH FOR VARIABILITY AND TRANSIT SIGNATURES IN HIPPARCOS PHOTOMETRIC DATA Badrinath Thirumalachari San Francisco State University 2018 The study and characterization of exoplanets has picked up pace rapidly over the past few decades with the invention of newer techniques and instruments. Detecting transits in stellar photometric data around stars already known to harbor exoplanets is crucial for exoplanet characterization. Due to these advancements we now have oceans of data and coming up with an automated way of performing exoplanet characterization is a challenge. In this thesis I describe one such method to search for transits in Hipparcos dataset containing photometric data for over 118000 stars. The radial velocity method has discovered a lot of planets around bright host stars and a follow up transit detection will give us the density of the exoplanet. -

The Political Thought of Al-Jahiz with Special Reference to the Question of Khilafa (Imamate): a Chronological Approach
THE POLITICAL THOUGHT OF AL-JAHIZ WITH SPECIAL REFERENCE TO THE QUESTION OF KHILAFA (IMAMATE): A CHRONOLOGICAL APPROACH (VOLUME II) JAMAL F. EL-'ATTAR THESIS PRESENTED FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF EDINBURGH 1996 -0. Wa NYý, w t --h CHAPTER EIGHT al-Wäthiq's Period I: (227-229) 1.Kitäb Fadl Hashim °alä `Abd Shams. 1-Note on Nomenclature : al-Jähiz in his famous preface to Kitdb al-Hayawän868refers to Kitäb Fadl Häshim as "Kitab Farq mä bayn Häshim wa `Abd Shams". The difference in nomenclature does not alter its authenticity, and seemsto have been acceptedby the leading experts on al-Jähiz869 al-Häjiri in his analysis of this work suggests that it belongs in the same religio-political setting as al-Näbita. 870 He adds that he is not sure of the relation between this work and a similar one quoted by Yäqüt in his bibliography of Jähiz's writings. This work - according to the authority of Yäqüt - is named "Kitäb al Fakhr mä bayn `Abd Shams wa Makhzüm", and since it has not reached us, there is no point of making any further comment on it. 871 As regards the relation between Kitäb Fadl Häshim and the series of works known as al-Häshimiyyät, mentioned by Jähiz himself in his preface to Kitäb al- Hayawän, as distinct from Kitäb Fadl Häshim, one may say here that there is obviously a common Hdshimite theme that runs through these writings, in the constant attempt of al-Jähiz to raise the two wings of the Häshimite stock against their Umayyad opponents, and in his no less eager efforts to undermine and marginalize the Umayyads by pointing out that as regards their relation to Quraysh, which then provided the socio-genetic pool for all political leaders - it was a very poor relation and not as central as that enjoyed by the Tälibites and `Abbäsids. -

These stars, namely, HD 34445, HD 126614, HD13931, and Gl179, all show evidence for a single planet in Keplerian motion. We also present Doppler measurements from the Hobby-Eberly Telescope (HET)fortwoofthestars,HD34445and Gl 179, that confirm the Keck detections and significantly refine the orbital parameters. These planets add to the statistical properties of giant planets orbiting near or beyond the ice line, and merit follow- up by astrometry, imaging, and space-borne spectroscopy. Their orbital parameters span wide ranges of planetary minimum mass (M sin i =0.38–1.9MJup), orbital period (P =2.87–11.5yr), semi-major axis (a =2.1–5.2AU),andeccentricity(e =0.02–0.41).

ABSTRACT Current technology and theoretical methods are allowing for the detection of sub-Earth sized extrasolar planets. In addition, the detection of massive moons orbiting extrasolar planets (“exomoons”) has become feasible and searches are currently underway. Several extrasolar planets have now been discovered in the habitable zone (HZ) of their parent star. This naturally leads to questions about the habitability of moons around planets in the HZ. Red dwarf stars present interesting targets for habitable planet detection. Compared to the Sun, red dwarfs are smaller, fainter, lower mass, and much more numerous. Due to their low luminosities, the HZ is much closer to the star than for Sun-like stars. -

Yet, many published exoplan- ets lack a measurement of their true mass, in particular those detected thanks to radial velocity (RV) variations of their host star. For those, only the minimum mass, or m sin i, is known, owing to the insensitivity of RVs to the inclination of the detected orbit compared to the plane-of-the-sky. The mass that is given in database is generally that of an assumed edge-on system (∼90◦), but many other inclinations are possible, even extreme values closer to 0◦ (face-on). In such case, the mass of the published object could be strongly underestimated by up to two orders of magnitude. -
Evidence for Enhanced Chromospheric Ca II H and K Emission in Stars with Close-In Extrasolar Planets
A&A 540, A82 (2012) Astronomy DOI: 10.1051/0004-6361/201118247 & c ESO 2012 Astrophysics Evidence for enhanced chromospheric Ca II H and K emission in stars with close-in extrasolar planets T. Krejcovᡠ1 and J. Budaj2 1 Department of Theoretical Physics and Astrophysics, Masaryk University, Kotlárskᡠ2, 61137 Brno, Czech Republic e-mail: [email protected] 2 Astronomical Institute, Slovak Academy of Sciences, 05960 Tatranská Lomnica, Slovak Republic e-mail: [email protected] Received 11 October 2011 / Accepted 13 February 2012 ABSTRACT Context. The planet-star interaction is manifested in many ways. It has been found that a close-in exoplanet causes small but mea- surable variability in the cores of a few lines in the spectra of several stars, which corresponds to the orbital period of the exoplanet. Stars with and without exoplanets may have different properties. Aims. The main goal of our study is to search for the influence that exoplanets might have on atmospheres of their host stars. Unlike the previous studies, we do not study changes in the spectrum of a host star or differences between stars with and without exoplanets. We aim to study a large number of stars with exoplanets and the current level of their chromospheric activity and to look for a possible correlation with the exoplanetary properties. Methods. To analyse the chromospheric activity of stars, we exploited our own and publicly available archival spectra, measured the equivalent widths of the cores of Ca II H and K lines, and used them to trace their activity. Subsequently, we searched for their dependence on the orbital parameters and the mass of the exoplanet.
