Additional JWST/NIRSpec Transits of the Rocky M Dwarf Exoplanet GJ 1132 b Reveal a Featureless Spectrum

As an archetypal M-dwarf rocky exoplanet, GJ 1132 b has a varied history of atmospheric measurements. At 1.13 R _⊕ , 1.66 M _⊕ , and 580 K, it orbits a bright, slowly rotating M dwarf in a 1.6 day period, making it a prime target for characterization. In this study, we combine two JWST NIRSpec/G395H...
