Cool, Cloudy Nights on an Ultrahot Neptune: A Panchromatic NIRISS/NIRSpec Transmission Spectrum of LTT 9779 b
Sarah Stamer, Diana Dragomir, Annabella Meech +13
Studies of planets that reside in the hot Neptune desert allow us to gain insight into how their atmospheres survive the intense flux from their host stars. One such member of that…
WINERED Detects a Strong Atmospheric Outflow on the Sub-Neptune GJ 3090b
Shreyas Vissapragada, Zifan Lin, Annabella Meech +12
Sub-Neptunes are the most common short-period ( d) planets known. A major goal for the field is to build a comprehensive understanding of their compositions and evolutionary…
Helium escaping from the atmosphere of a nearby rocky exoplanet orbiting in a habitable zone
Collin Cherubim, Shreyas Vissapragada, Tim Cunningham +13
Observations of highly irradiated gas giant exoplanets have shown helium escaping from their atmospheres. There is limited evidence for atmospheres on rocky exoplanets, perhaps bec…
JWST COMPASS Program: The 3--5m transmission spectrum of LTT 1445 A b
Natasha E. Batalha, Nicole Wallack, Tyler Gordon +16
The search for an atmosphere on the closest rocky M dwarf planet, LTT 1445 A b, has been the subject of intense investigation from both the ground and space. Here, we present the f…
BOWIE-ALIGN: Exploring degeneracies in the muted transmission spectrum of the aligned hot Jupiter NGTS-2b with NIRSpec/G395H
Charlotte Fairman, Hannah R. Wakeford, Alastair B. Claringbold +15
We present the first atmospheric observation and characterisation of the aligned, 1468 K hot Jupiter, NGTS-2b, with one JWST NIRSpec/G395H transit. These observations complete the…
JWST COMPASS: A NIRSpec G395H Transmission Spectrum of Radius Valley-Dweller TOI-260 b
Annabella Meech, Peter Gao, Nicole L. Wallack +16
We present a JWST/NIRSpec G395H transmission spectrum of TOI-260 b, a K, planet. The transmission spectrum is derived by com…
JWST COMPASS: NIRSpec/G395H Transmission Observations of the Sub-Neptune HD 15337 c
Nicole L. Wallack, Peter Gao, Michael Greklek-McKeon +17
We present the 3-5 m transmission spectrum of HD 15337 c (TOI-402.02), a sub-Neptune (2.526 R, 6.792 M, T656 K) around a K1V star observed…
BOWIE-ALIGN: Sub-solar C/O ratio and metallicity atmosphere of the misaligned hot Jupiter HAT-P-30b
Alastair B. Claringbold, Chloe E. Fisher, James Kirk +18
We present the JWST NIRSpec/G395H transmission spectrum of the misaligned hot Jupiter HAT-P-30b from 2.8--5.2 m as part of the BOWIE-ALIGN survey, a comparative survey designed…
Mass estimates of the young TOI-451 transiting planets: Multidimensional Gaussian Process on stellar spectroscopic and photometric signals
Oscar Barragán, Manuel Mallorquín, Jorge Fernández-Fernández +30
The young TOI-451 planetary system, aged 125 Myr, provides a unique opportunity to test theories of planetary internal structures and atmospheric mass loss through examination of i…
