A Dark, Bare Rock for TOI-1685 b from a JWST NIRSpec G395H Phase Curve

A Dark, Bare Rock for TOI-1685 b from a JWST NIRSpec G395H Phase Curve

We report JWST NIRSpec/G395H observations of TOI-1685 b, a hot rocky super-Earth orbiting an M2.5V star, during a full orbit. We obtain transmission and emission spectra of the planet and characterize the properties of the phase curve, including its amplitude and offset. The transmission spectrum ru...
