JWST COMPASS: A NIRSpec G395H Transmission Spectrum of the Super-Earth GJ 357 b
We present JWST NIRSpec/G395H transmission spectroscopy observations of GJ 357 b, a warm ( T _eq ≈ 525 K) super-Earth (1.2 R _⊕ , 1.84 M _⊕ ) orbiting a nearby M3-type star, with a median precision of 18 ppm and 27 ppm in NRS1 and NRS2, respectively. These precisions are obtained by binning the spe...
