Close-Orbiting Exoplanets: Formation, Migration Mechanisms and Properties

2008
The discovery of a signal from a putative extra-solar planet around the nearby Sun-like star 51 Peg by Mayor & Queloz and the rapid confirmation by Marcy & Butler was the main starting point for the field of extrasolar planets. More than a decade later, ‘51 Peg - type planets’ or ‘hot Jupiters’ are frequently discovered and characterised by a variety ...

Formation and Migration Histories of Giant Exoplanets in Multi-stellar Systems

2017
The first planets discovered outside of our solar system were very different from the solar system planets. These discoveries raised new challenges to planet formation models, which were designed to explain the origin of the solar system planets. One particularly intriguing population, the "hot Jupiters" were some of the first planets discovered. These

Exploring Exoplanets' Spectroscopic Secrets: Clues on the Migration and Formation of Hot Jupiters

2018
Before the mid-90's, scientists' theories for planet formation were finely-tuned to explain the existence of our own Solar System. These theories were thrown into disarray when astronomers began to discover exoplanets, or planets in other solar systems.

Exoplanets in Open Clusters and Binaries: New Constraints on Planetary Migration

2016
In this dissertation, we present three complementary studies of the processes that drive planetary migration. The first is a radial-velocity survey in search of giant planets in adolescent (Gyr) open clusters. While several different mechanisms may act to drive giant planets inward, only some mechanisms will excite high eccentricities while doing so ...

Outward Migration of Low-Mass Planets: A Key to Observed Exoplanet Demographics

The rapidly expanding catalog of exoplanets reveals a striking diversity in planetary system architectures, characterized by the prevalence of super-Earths and mini-Neptunes, and distinctive features such as the "radius valley." While inward migration has long been established as a dominant process, particularly for hot Jupiters, the role of outward ...

Searching for Snapshots of Giant Exoplanet Migration

NEID, an extreme precision Doppler spectrograph on the WIYN 3.5-meter Telescope at Kitt Peak National Observatory (a partnership between Indiana University, University of Wisconsin-Madison, Pennsylvania State University, Princeton University,Purdue University, NSF’s NOIRLab, and NASA), is helping unravel the origin of hot Jupiters.
