Finding Habitable Exoplanets with Binary Relative Astrometry: Planet Detection and Characterization with the Microarcsecond Astrometric Retrieval Algorithm (MARA)
William Roberson, Eric L. Nielsen, Jessie L. Christiansen +8
Binary relative astrometry is a technique to search for rocky planets in the habitable zone of nearby binary stars using 1D relative astrometry at the microarcsecond level. This un…
Assessing Planetary Stability and Long-Term Habitability in Nearby Stellar Binaries: 70 Oph, 36 Oph, Leo
Alyssa R. Jankowski, Juliette Becker, Catherine A. Clark +8
Binary stars are common and have the potential to host habitable planets, which may reside in more complex habitable zones as compared to planets orbiting single stars. In this wor…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Searching for Habitable Exoplanets with Relative Astrometry (SHERA). I. The Case for Searching for Planets in Binary Star Systems
Jessie L. Christiansen, Eric E. Mamajek, Gautam Vasisht +14
Discovering Earth-like planets orbiting Sun-like stars was identified as a priority science goal of the Astronomy 2020 Decadal Survey. It is confounded by many factors, one of whic…
Do Super-Puffs Defy Core Accretion? Population-Wide Interior Structure Constraints
Nicholas T. Marston, Juliette Becker, Alex R. Howe
Sub-Saturn mass planets with extremely low bulk densities , or ``super-puffs'', are one of the most interesting and least understood populations of e…
A Century of Radial Velocity and Astrometric Monitoring of 70 Oph AB: New PFS Data and Constraints on Planetary Companions
Yiting Li, Michael R. Meyer, Skylar D'Angiolillo +29
At a distance of 5.1 pc, the 70 Oph AB binary star system is one of the most favorable targets for future direct imaging and astrometry missions surveying mature, terrestrial plane…
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…
