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…
ADORA: a differentiable optical modeling and astrometric retrieval framework for SHERA
Dylan McKeithen, Stuart Shaklan, Gautam Vasisht +4
Searching for Habitable Exoplanets with Relative Astrometry (SHERA) is a proposed Small Explorer mission concept designed to measure the separation of nearby binary stars at microa…
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…
Investigating the differential limb coupling effect for diffraction-limited spectrographs with PARVI
Andrea S. J. Lin, Ashley D. Baker, Samuel Halverson +5
A promising new architecture for extreme-precision radial velocity (EPRV) spectrographs, hunting for small-amplitude stellar Doppler shifts induced by orbiting planets, is to build…
Exploring Exoplanets with Interferometry
Sascha P. Quanz, Bertrand Mennesson, Charles Beichman +27
(Extract from the Executive Summary) Humanity stands at the threshold of answering one of its most profound questions: Does life exist beyond Earth? Ongoing and upcoming space miss…
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…
