A Spatial Map of the Atmospheric Limb of a Hot Jupiter
Lili Alderson, Hannah R. Wakeford, David Grant +18
Planets are inherently three-dimensional objects shaped by their thermal structure and dynamics. Observations of transiting exoplanets have begun to uncover this three-dimensional…
K-dwarf starspot hunters: how to directly characterize spot and faculae properties with UV-IR panchromatic transit spectra
Joanna K. Barstow, Caitlyn Cullen, Yvonne Unruh +7
Transmission spectroscopy of exoplanets provides an important window into their atmospheric composition, structure and dynamics, especially in the JWST era. As the quality of the o…
TESS Photometry and Radial Velocity Analysis of the sub-Neptune Exoplanet π Mensae c and the Wider π Mensae Planetary System
Skylar S. Larsen, Jake D. Turner, Nikole K. Lewis +10
Exoplanet characterization relies on precise measurements of planetary orbital and physical parameters. This is particularly important for planetary dynamics and atmospheric evolut…
The HST/WFC3 Transmission Spectrum of AU Mic b Part I: An Atmosphere Obscured by Contamination and Systematics
William C. Waalkes, Peter Gao, Elisabeth Newton +10
Young sub-Neptune progenitors around M dwarfs offer an excellent opportunity to probe the formation of their abundant, older cousins. At 20 Myr and only 9.7 pc away, AU Mic b…
Characterizing Transiting Exoplanet Atmospheres in the 2030s with the Hubble Space Telescope
Joshua D. Lothringer, Hannah R. Wakeford, Robert C. Frazier +7
The Hubble Space Telescope inaugurated the era of exoplanet atmospheric characterization. While the James Webb Space Telescope has largely taken up the mantle of infrared atmospher…
Magnesium Silicate Clouds in the Atmosphere of HD 209458b from a Rule-Based Tree-Structured Data Reduction
Katy L. Chubb, David Grant, Hannah R. Wakeford +14
HD 209458b is the canonical hot Jupiter: the first to have its atmosphere measured and the first to hint at the role of aerosols in exoplanet atmospheres through the muting of Na a…
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…
