Worlds Next Door. V. A Candidate Solar System Scale Super-Jupiter in the 61 Cygni Binary System
Aniket Sanghi, Billy Quarles, Andrea S. J. Lin +16
We present new constraints on a candidate third companion in the 61 Cygni binary system-one of the closest neighbors to our solar system (3.5 pc), the first stars to have a measure…
The Science Potential of Characterizing Gas Giant Exoplanets with HWO
Beck Dacus, Jean-Baptiste Ruffio, Quinn Konopacky +19
With the ability to directly image Earth-like exoplanets and search their atmospheres for biosignatures, the upcoming Habitable Worlds Observatory (HWO) will also collect high sign…
The Roman Coronagraph Community Participation Program: calibration strategy for the Mueller matrix using on-sky sources
Toshiyuki Mizuki, Justin Hom, Bertrand Mennesson +14
The Nancy Grace Roman Space Telescope Coronagraph Instrument will provide space-based polarimetric observations of circumstellar disks and exoplanetary systems. Accurate reconstruc…
The Roman Coronagraph Community Participation Program: early calibration plan and pilot observation of a companion
Julien H. Girard, Eric Cady, Neil T. Zimmerman +42
Roman is set to launch in weeks! The Coronagraph Instrument - technology pathfinder for future direct imaging missions - is ready to fly too. According to predictions, laboratory t…
The Roman Coronagraph Community Participation Program: Observation planning and data reduction for polarimetric mode
Ramya M Anche, Toshiyuki Mizuki, Justin Hom +25
Reflected-light polarimetry of exoplanets constrains and resolves degeneracies in atmospheric properties, while polarized light observations of debris disks enable the characteriza…
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…
Characterizing Earth analogs may require a moderate or high-resolution spectrograph
Jean-Baptiste Ruffio, Sarah Steiger, Corey Spohn +16
A primary goal of the Habitable Worlds Observatory (HWO) is to detect and measure the abundance of biosignature molecules, such as water (H2O) and oxygen (O2), in the atmosphere of…
Dimpled scalar vortex coronagraph laboratory demonstration
Niyati Desai, Garreth Ruane, Susan Redmond +3
Achieving the Habitable Worlds Observatory (HWO) goal of 10^-10 contrast at a separation of 3 /D across a 20% bandwidth requires coronagraph focal plane masks with both broadban…
Model validation and tolerancing of scalar vortex masks in the High Contrast Imaging Testbed (HCIT) facility
Niyati Desai, Garreth Ruane, Daniel Shanks +3
The Habitable Worlds Observatory (HWO) mission will require coronagraphs capable of suppressing starlight at the contrast level to directly image exo-Earths. High c…
Habitable Worlds Observatory's Concept and Technology Maturation: Initial Feasibility and Trade Space Exploration
Lee D. Feinberg, Breann N. Sitarski, Michael W. McElwain +10
The Habitable Worlds Observatory is the first telescope ever designed to search for life and will be a powerhouse of discovery across topics in astrophysics. The observatory was th…
