High contrast imaging with the AstroPIC integrated photonic coronagraph

Rachel Morgan, Ruslan Belikov, Eduardo Bendek, Kevin Fogarty et autres

Integrated photonics is a promising coronagraph technology option for increasing the Exo-Earth science yield of NASA’s Habitable Worlds Observatory and relaxing key observatory requirements. A photonic integrated circuit (PIC) coronagraph is theoretically capable of achieving extremely high performance because arrays of integrated …

Development path and verification for HabWorlds deformable mirrors

Tyler D. Groff, Hari Subedi, Evan Bray, Caleb Baker et autres

Deformable Mirrors (DMs) are the critical component for the Habitable Worlds Observatory (HWO). A baseline set of device requirements was set for a short feasibility study by some key DM vendors. Included in these requirements are previously untestable tolerances for which a …

Wavefront control for experimental verification of simulated contrast performance for the AstroPIC photonic coronagraph

Kevin Fogarty, Rachel Morgan, Ruslan Belikov, Eduardo Bendek et autres

Photonic coronagraphy has the potential to dramatically improve our ability to target faint, small-separation exoplanets with future missions such as the HabitableWorlds Observatory. A practical photonic integrated circuit (PIC) coronagraph will need to be able to create a dark zone in multiple …

Coupling free space light into the AstroPIC photonic coronagraph

Eduardo Bendek, Ruslan Belikov, Simon A. Bongarz, Ryosuke Mashiko et autres

The Habitable Worlds Observatory (HWO) aims to reach a planet-to-star contrast near 10−10 to detect and characterize Earth-like planets in reflected starlight. The mission exoplanet yield is sensitive to the coronagraph inner working angle and to the end-to-end observatory throughput, including the …

Wavefront sensing with photonic lanterns and integrated circuits

Jonathan Lin, Rachel Morgan, Ruslan Belikov, Dan Sirbu et autres

The next generation of high-contrast exoplanet imagers will require precise correction of quasistatic, contrast degrading aberrations stemming from non-common optical paths, the low-wind effect, and petaling. I consider how two emerging technologies– photonic lanterns and integrated circuits– may improve the state-of-the-art, yielding …

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, Gautam Vasisht et autres

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 unprecedented precision would allow a custom-designed space telescope to directly measure the occurrence rate …

TOLIMAN mission: a low-cost space telescope for high-precision narrow-angle astrometry (Erratum)

Peter Tuthill, Christopher Betters, Max Charles, Fred Crous et autres

This erratum corrects an error in the originally published article TOLIMAN mission: a low-cost space telescope for high-precision narrow-angle astrometry.

Assessing Planetary Stability and Long-Term Habitability in Nearby Stellar Binaries: 70 Oph, 36 Oph, $γ$ Leo

Alyssa R. Jankowski, Juliette Becker, Catherine A. Clark, Eric E. Mamajek et autres

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 work, we use numerical simulations to assess the possibility that bright, nearby stellar …

Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory

Courtney D. Dressing, D. Adams, E. Alécian, Gagandeep Anand et autres

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 should conduct "transformative astrophysics" and search for biosignatures in the atmospheres of approximately 25 potentially …

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, Catherine A. Clark et autres

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 which is the high multiplicity of Sun-like stars in the local neighborhood - half of …
