Photonic Integrated Circuits for the Habitable Worlds Observatory: Science Drivers, Material Platforms, Arrayed-Waveguide Spectrographs, and a Space-Qualification Roadmap
[astro-ph.IM] NASA’s Habitable Worlds Observatory (HWO) will require ultraviolet, optical, and near-infrared instruments that are simultaneously compact, mechanically and thermally stable, high-throughput, and replicable at large channel counts.

JWST/MIRI Imaging Search for Kinematically Detected Protoplanetary Candidates
[astro-ph.EP] Kinematic perturbations observed with ALMA in CO line emission provide evidence for a population of embedded giant protoplanets shaping the structure of protoplanetary disks.
![Sensitivity of the adopted contrast curves for the newly validated planets, separated by technique. Each pixel gives the fraction of curves sensitive to a companion of the given magnitude contrast (∆mag) at the given angular separation (∆arcsec), shading from white (all curves sensitive) to black (none sensitive). Speckle observations are confined to their ∼ 1.2 ′′ field of view, while the adaptive-optics curves extend to wider separations. Contrasts are in each observation’s native band and are not directly comparable across instruments (cf. Table 2).-- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/Assessing-the.png?resize=1200%2C720&ssl=1)

Assessing the Impact of High-Resolution Imaging on Statistical Validation of TESS Planet Candidates
[astro-ph.EP] High-resolution imaging is widely used to constrain false-positive scenarios in exoplanet validation, but it is a finite follow-up resource that reaches only a subset of candidates, and its population-level […]
