The tale of the 3 planets: 3D cloud feedback enhances the spectral diversity of warm Jupiters
Nishil Mehta, Vivien Parmentier, Xianyu Tan +14
JWST has shown a large diversity in warm Jupiter spectra, despite only small variations in the planetary parameters. However, the main driver of this diversity remains unclear. We…
NASA's Pandora SmallSat Mission: Simulating the Impact of Stellar Photospheric Heterogeneity and Its Correction
Benjamin V. Rackham, Aishwarya R. Iyer, Dániel Apai +28
Stellar photospheric heterogeneity is a dominant astrophysical systematic impacting exoplanet transmission spectroscopy. NASA's Pandora SmallSat Mission is designed to address this…
The Identification of CS2 and Evidence for Carbon-Sulfur Chemical Coupling in a Warm Giant Exoplanet Atmosphere
Anastasia Triantafillides, Thomas G. Beatty, Matthew C. Nixon +14
Transmission spectroscopy with the James Webb Space Telescope (JWST) is revealing growing chemical complexity in giant exoplanet atmospheres. Of particular interest is sulfur, whic…
NASA's Pandora SmallSat Mission: Simulated Modeling and Retrieval of Near-Infrared Exoplanet Transmission Spectra
Yoav Rotman, Peter McGill, Luis Welbanks +22
Pandora is a SmallSat mission dedicated to understanding exoplanets and their host stars by disentangling the impact of stellar heterogeneity on exoplanet transmission spectra. Sel…
Retrievals on NIRCam transmission and emission spectra of HD 189733b with PLATON 6, a GPU code for the JWST era
Michael Zhang, Kimberly Paragas, Jacob L. Bean +5
We present the 2.4--5.0 \um JWST/NIRCam emission spectrum of HD 189733b, along with an independent re-reduction of the previously published transmission spectrum at the same wavele…
Comparing key compositional indicators in Jupiter with those in extra-solar giant planets
J. I. Lunine, T. Greene, C. Beichman +3
Spectroscopic transiting observations of the atmospheres of hot Jupiters around other stars, first with Hubble Space Telescope and then Spitzer, opened the door to compositional st…
Characterizing Transiting Planet Atmospheres through 2025
N. B. Cowan, T. Greene, D. Angerhausen +13
[Abridged] We have only been able to comprehensively characterize the atmospheres of a handful of transiting planets, because most orbit faint stars. TESS will discover transiting…
