JWST COMPASS: The first near- to mid-infrared transmission spectrum of the hot super-Earth L 168-9 b
Munazza K. Alam, Peter Gao, Jea Adams Redai +14
We present the first broadband near- to mid-infrared (3-12 microns) transmission spectrum of the highly-irradiated (T_eq = 981 K) M dwarf rocky planet L 168-9 b (TOI-134 b) observe…
JWST COMPASS: The 3-5 Micron Transmission Spectrum of the Super-Earth L 98-59 c
Nicholas Scarsdale, Nicholas Wogan, Hannah R. Wakeford +14
We present a JWST NIRSpec transmission spectrum of the super-Earth exoplanet L 98-59 c. This small (RR, MR), warm (T$_\textrm{eq…
A Benchmark JWST Near-Infrared Spectrum for the Exoplanet WASP-39b
A. L. Carter, E. M. May, N. Espinoza +77
Observing exoplanets through transmission spectroscopy supplies detailed information on their atmospheric composition, physics, and chemistry. Prior to JWST, these observations wer…
Sulphur dioxide in the mid-infrared transmission spectrum of WASP-39b
Diana Powell, Adina D. Feinstein, Elspeth K. H. Lee +70
The recent inference of sulphur dioxide (SO) in the atmosphere of the hot (1100 K), Saturn-mass exoplanet WASP-39b from near-infrared JWST observations suggests that phot…
Debris Disks can Contaminate Mid-Infrared Exoplanet Spectra: Evidence for a Circumstellar Debris Disk around Exoplanet Host WASP-39
Laura Flagg, Alycia J. Weinberger, Taylor J. Bell +21
The signal from a transiting planet can be diluted by astrophysical contamination. In the case of circumstellar debris disks, this contamination could start in the mid-infrared and…
Non-Detections of Helium in the Young Sub-Jovian Planets K2-100b, HD 63433b, & V1298 Tau c
Munazza K. Alam, James Kirk, Leonardo A. Dos Santos +10
We search for excess in-transit absorption of neutral helium at 1.083 m in the atmospheres of the young (<800 Myr) sub-Jovian (0.2-0.5 ) planets HD 63433b, K2-100b, a…
Using JWST transits and occultations to determine stellar radii and temperatures of low-mass stars
Alexandra S. Mahajan, Jason D. Eastman, James Kirk
Using JWST observations of a primary transit and two secondary eclipses for GJ 1214b, we determine an eccentricity that is more precise than a decade of HARPS data, which enables u…
JWST COMPASS: A NIRSpec/G395H Transmission Spectrum of the Sub-Neptune TOI-836c
Nicole L. Wallack, Natasha E. Batalha, Lili Alderson +13
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. Now that we are fi…
JWST COMPASS: NIRSpec/G395H Transmission Observations of the Super-Earth TOI-836b
Lili Alderson, Natasha E. Batalha, Hannah R. Wakeford +13
We present two transit observations of the ~870K, 1.7R super-Earth TOI-836b with JWST NIRSpec/G395H, resulting in a 2.8-5.2m transmission spectrum. Using two different reduc…
JWST/NIRCam Transmission Spectroscopy of the Nearby Sub-Earth GJ 341b
James Kirk, Kevin B. Stevenson, Guangwei Fu +17
We present a JWST/NIRCam transmission spectrum from m of the recently-validated sub-Earth GJ 341b ( , …
