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…
Data post-processing gain resulting from the patchy nature of speckles
Jean-Baptiste Ruffio, Laurent Pueyo
The data post-processing gain is an important parameter for exposure time calculations used to inform the design of the Habitable Worlds Observatory (HWO). Assuming azimuthally sym…
Direct imaging characterization of cool gaseous planets
Michiel Min, Jo Barstow, Laura C. Mayorga +19
Cool gas giant exoplanets, particularly those with properties similar to those of Jupiter and Saturn, remain poorly characterized due to current observational limitations. This whi…
Habitable World Discovery and Characterization: Coronagraph Concept of Operations and Data Post-Processing
Michael W. McElwain, Dimitri Mawet, Jean-Baptiste Ruffio +11
The discovery and characterization of habitable worlds was the top scientific recommendation of the Astro2020 decadal survey and is a key objective of the Habitable Worlds Observat…
Identifying rocky planets and water worlds among sub-Neptune-sized exoplanets with the Habitable Worlds Observatory
Renyu Hu, Michiel Min, Max Millar-Blanchaer +15
Astronomers are debating whether the plentiful "sub-Neptune" exoplanets -- worlds a bit larger than Earth but smaller than Neptune -- are predominantly rocky planets, water-rich "o…
Technical description and performance of the phase II version of the Keck Planet Imager and Characterizer
Nemanja Jovanovic, Daniel Echeverri, Jacques-Robert Delorme +46
The Keck Planet Imager and Characterizer (KPIC) is a series of upgrades for the Keck II Adaptive Optics (AO) system and the NIRSPEC spectrograph to enable diffraction limited, high…
