Using Scattered Near-Infrared Light to Map Water Ice in Prestellar Cores with SPHEREx
Tamojeet Roychowdhury, Jennifer B. Bergner, Jens Kauffmann +2
We present the first coreshine-derived, spatially-resolved maps of the 3 m HO ice absorption feature in four prestellar cores, using SPHEREx spectra. Ices are a key compone…

New Orbital Constraints for YSES 1 b and HR 2562 B from High-Precision Astrometry and Planetary Radial Velocities
Jonathan Roberts, William Thompson, Jason J. Wang +20
We present new VLTI/GRAVITY astrometry and updated orbit fits for the directly imaged companions YSES 1 b and HR 2562 B, substellar objects straddling the planet-brown dwarf bounda…
