A Highly Reflective Atmosphere on the Lava World TOI-561b Revealed by JWST/NIRSpec Phase Curve
Samuel Boucher, Lisa Dang, Alex McGinty +15
Ultra-short period (USP) rocky planets are expected to be depleted of any substantial gaseous envelope due to the intense irradiation they receive from their host star, making the…

A Thick Volatile Atmosphere on the Ultrahot Super-Earth TOI-561 b
Johanna K. Teske, Nicole L. Wallack, Anjali A. A. Piette +10
Ultrashort-period (USP) exoplanets -- with R and periods 1 day -- are expected to be stripped of volatile atmospheres by intense host star irradiation…
