Astrometric Evidence for Outer Giant Planets in Known Exoplanet Systems
Clarissa R. Do Ó, William Thompson, Dori Blakely +19
Outer giant planets can influence the formation and dynamical evolution of their planetary systems. However, their long orbital periods make them difficult to detect using transit…
Impacts of Correlated Noise on Retrievals of Exo-Earth Atmospheres
Nicole Wolff, Bruce Macintosh, Tyler D. Robinson +6
The Habitable Worlds Observatory (HWO) aims to accomplish high-contrast imaging and spectroscopy of true Earth analogs for the first time. However, high-contrast spectroscopy with…
Radial Velocity Strategies for the Orbital Refinement of Exoplanet Direct Imaging Targets
Zhexing Li, Stephen R. Kane, Sarah Blunt +1
Many potential direct imaging candidates suffer from large orbital period uncertainties, leading to challenges in accurate predictions of future orbital positions and imprecise dir…
Requirements for Joint Orbital Characterization of Cold Giants and Habitable Worlds with Habitable Worlds Observatory
Sabina Sagynbayeva, Asif Abbas, Stephen R. Kane +10
We determine optimal requirements for the joint detection of habitable-zone planets and cold giant planets with the Habitable Worlds Observatory (HWO). Analysis of 164 nearby stars…
A Statistical Method for Constraining the Capability of the Habitable Worlds Observatory to Understand Ozone Onset Time in Earth Analogs
Sarah Blunt, Eric L. Nielsen, Elisabeth R. Newton +8
The oxygenation of Earth's atmosphere 2.3 billion years ago, which on exoplanets is expected to be most detectable via the UV ozone feature at 0.25 m, is often regarded as…
Evidence that the Directly-Imaged Planet HD 131399 Ab is a Background Star
Eric L. Nielsen, Robert J. De Rosa, Julien Rameau +55
We present evidence that the recently discovered, directly-imaged planet HD 131399 Ab is a background star with non-zero proper motion. From new JHK1L' photometry and spectroscopy…
