Leveraging Impact Parameter to Mitigate the Transit Light Source Effect: Early Insights from TRAPPIST-1

Ana Glidden, Alexander I. Shapiro, Sara Seager +19

Stellar activity complicates exoplanet transmission spectra, particularly for smaller planets around M dwarfs with JWST. The transit light source (TLS) effect, the imprinting of sp…

The panchromatic JWST dayside spectrum of WASP-121 b reveals a refractory-rich formation

K. Angelique Kahle, Paul Mollière, Laura Kreidberg +16

One path to understand how planets form is to link their present-day atmospheric composition to predictions from planet formation models. For the hottest planets, the abundances of…

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…

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…

Transformational astrophysics and exoplanet science with Habitable Worlds Observatory's High Resolution Imager

Vincent Van Eylen, Richard Massey, Saeeda Awan +167

Habitable Worlds Observatory (HWO) will be NASA's flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.…

JWST TRAPPIST-1 e/b Program: Motivation and first observations

Natalie H. Allen, Néstor Espinoza, V. A. Boehm +24

One of the forefront goals in the field of exoplanets is the detection of an atmosphere on a temperate terrestrial exoplanet, and among the best suited systems to do so is TRAPPIST…
