COUNTESS I: A Uniformly Vetted Catalog of Known and New Transiting Exoplanets in the TESS Northern Continuous Viewing Zone
Andrew Hotnisky, Rachel B. Fernandes, Kevin K. Hardegree-Ullman +9
The Transiting Exoplanet Survey Satellite (TESS) has transformed the study of nearby exoplanetary systems; however, its nominal observing strategy limits sensitivity to planets wit…
Hot Jupiters' Isolation Is Not Unique to High-Eccentricity Tidal Migration
Brandon Radzom, Songhu Wang, Bonan Pu +2
Conventionally, the observed isolation of hot Jupiters, marked by a paucity of nearby low-mass planetary companions, has been interpreted as evidence of high-eccentricity tidal mig…
Evidence for Primordial Alignment II: Insights from Stellar Obliquity Measurements for Hot Jupiters in Compact Multiplanet Systems
Brandon Thomas Radzom, Jiayin Dong, Malena Rice +5
A significant fraction of hot Jupiters have orbital axes misaligned with their host stars' spin axes. The large stellar obliquities of these giants have long been considered potent…
Evidence for Primordial Alignment: Insights from Stellar Obliquity Measurements for Compact Sub-Saturn Systems
Brandon T. Radzom, Jiayin Dong, Malena Rice +5
Despite decades of effort, the mechanisms by which the spin axis of a star and the orbital axes of its planets become misaligned remain elusive. Particularly, it is of great intere…
