Speckle Imaging Characterization of Radial Velocity Exoplanet Systems [PDF]
Astronomical Journal, 2020 We conducted speckle imaging observations of 53 stellar systems that were members of long-term radial velocity (RV) monitoring campaigns and exhibited substantial accelerations indicative of planetary or stellar companions in wide orbits.

Follow-Up and Validation of K2 and TESS Planetary Systems With Keck NIRC2 Adaptive Optics Imaging
Frontiers in Astronomy and Space Sciences, 2021 High resolution imaging (HRI) is a critical part of the transiting exoplanet follow-up and validation process. HRI allows previously unresolved stellar companions and background blends to be resolved, vetting false positive signals and improving the ...

VaTEST. II. Statistical Validation of 11 TESS-detected Exoplanets Orbiting K-type Stars
The Astronomical Journal, 2023 NASA’s Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission designed to find transiting exoplanets orbiting nearby bright stars. It has identified more than 329 transiting exoplanets, and almost 6000 candidates remain unvalidated. In

Statistical Trends in the Obliquity Distribution of Exoplanet Systems [PDF]
Astronomical Journal, 2018 Important clues to the formation and evolution of planetary systems can be inferred from the stellar obliquity ψ. We study the distribution of obliquities using the California-Kepler Survey and the TEPCat Catalog of Rossiter–McLaughlin (RM) measurements,

Planet–Planet Occultations in TRAPPIST-1 and Other Exoplanet Systems [PDF]
, 2017 We explore the occurrence and detectability of planet–planet occultations (PPOs) in exoplanet systems. These are events during which a planet occults the disk of another planet in the same system, imparting a small photometric signal as its thermal or ...

Validating AU Microscopii d with Transit Timing Variations
The Astronomical Journal, 2023 AU Mic is a young (22 Myr), nearby exoplanetary system that exhibits excess transit timing variations (TTVs) that cannot be accounted for by the two known transiting planets nor stellar activity.
