Diversity of Cold Worlds: A Near Complete Spectral Energy Distribution for 2MASS J04151954-0935066 using JWST
We present the a near complete spectral energy distribution (SED) for an extrasolar world: the T8 brown dwarf 2MASS~J04151954−0935066. Spanning from optical to mid-infrared (0.7–20.4 micron) wavelengths, the SED for […]

Machine-assisted Classification Of Potential Biosignatures In Earth-like Exoplanets Using Low Signal-to-noise Ratio Transmission Spectra
The search for atmospheric biosignatures in Earth-like exoplanets is one of the most pressing challenges in observational astrobiology. Detecting biogenic gases in terrestrial planets requires high resolution and long integration […]

JWST COMPASS: The 3-5 Micron Transmission Spectrum of the Super-Earth L 98-59 c
We present a JWST NIRSpec transmission spectrum of the super-Earth exoplanet L 98-59 c. This small (Rp=1.385±0.085R⊕, Mp=2.22±0.26R⊕), warm (Teq=553K) planet resides in a multi-planet system around a nearby, bright […]

JWST COMPASS: A NIRSpec/G395H Transmission Spectrum Of The Sub-Neptune TOI-836c
Planets between the sizes of Earth and Neptune are the most common in the Galaxy, bridging the gap between the terrestrial and giant planets in our Solar System.
