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 measured parallax, and two of the most favorable targets for habitable zone exo-Earth searches with future direct imaging missions.

AstroPIC is a photonic integrated coronagraph concept for the Habitable Worlds Observatory (HWO) that uses a programmable Mach-Zehnder interferometer mesh to perform coronagraphic mode-sorting of starlight while preserving off-axis exoplanet light. This paper presents a Gen-2 technology update and modeling study. The G...

NASA is embarking on an ambitious program to develop the Habitable Worlds Observatory (HWO) flagship to perform transformational astrophysics, as well as directly image ∼25 potentially Earth-like planets and spectroscopically characterize them for signs of life. This mission was recommended by the Astro2020 decadal sur...

Building space telescopes with apertures of tens of meters is instrumental for next-generation astrophysics, including direct imaging and characterization of extrasolar planets. Traditional manufacturing and segmentedmirror approaches, such as those used for the JamesWebb Space Telescope, do not scale to these dimensio...
