Dynamical Interactions and Habitability in the TOI-700 Multi-Planet System
Coleman Nelson, Juliette Becker
The discovery of a second earth sized planet (TOI-700e) interior to the habitable candidate TOI-700d has prompted further research into this system, as the additional planet makes…
Warm Jupiter Tidal Migration Can Spare Inner Planets; Hot Jupiter Tidal Migration May Not
Juliette Becker
In this work, we investigate the dynamical survival of short-period inner planets during the high-eccentricity tidal migration of companion exterior giant planets. Using a combinat…
Investigating the Formation of Planets Interior to in situ Hot Jupiters
Devansh Mathur, Juliette Becker
The population of hot Jupiters with adjacent planetary companions is small but growing, and inner companions appear to be a nearly ubiquitous outcome within this subset of the exop…
General Relativity Can Prevent a Runaway Greenhouse on Potentially Habitable Planets Orbiting White Dwarfs
Eva Stafne, Juliette Becker
Planets orbiting in the habitable zones of white dwarfs have recently been proposed as promising targets for biosignature searches. However, since the white dwarf habitable zone re…
Astrometric Accelerations of Provisional Targets for the Habitable Worlds Observatory
Katie E. Painter, Brendan P. Bowler, Kyle Franson +2
NASA's Habitable Worlds Observatory (HWO) will be the first space telescope capable of directly imaging Earth-like planets in the habitable zones of Sun-like stars to probe their a…
New Field OB and OBe Binaries of the SMC Wing: Observational Properties and Population Modeling
Irene Vargas-Salazar, M. S. Oey, Jan J. Eldridge +9
We present a radial velocity (RV) survey of the field OB and OBe stars of the SMC Wing. We use multi-epoch observations of 55 targets obtained with the Magellan IMACS and M2FS mult…
