A new method to measure the spectra of transiting exoplanet atmospheres using multi-object spectroscopy
Vatsal Panwar, Jean-Michel Désert, Kamen O. Todorov +5
Traditionally, ground-based spectrophotometric observations probing transiting exoplanet atmospheres have employed a linear map between comparison and target star light curves (e.g…
The Hubble PanCET program: Transit and Eclipse Spectroscopy of the Hot Jupiter WASP-74b
Guangwei Fu, Drake Deming, Erin May +12
Planets are like children with each one being unique and special. A better understanding of their collective properties requires a deeper understanding of each planet. Here we add…
Retrieving Exoplanet Atmospheres using Planetary Infrared Excess: Prospects for the Nightside of WASP-43 b and other Hot Jupiters
Jacob Lustig-Yaeger, Kevin B. Stevenson, L. C. Mayorga +4
To increase the sample size of future atmospheric characterization efforts, we build on the planetary infrared excess (PIE) technique that has been proposed as a means to detect an…
On the Utility of Transmission Color Analysis I: Differentiating Super-Earths and Sub-Neptunes
Kristin S. Sotzen, Kevin B. Stevenson, Erin M. May +9
The majority of exoplanets found to date have been discovered via the transit method, and transmission spectroscopy represents the primary method of studying these distant worlds.…
No umbrella needed: Confronting the hypothesis of iron rain on WASP-76b with post-processed general circulation models
Arjun B. Savel, Eliza M. -R. Kempton, Matej Malik +6
High-resolution spectra are unique indicators of three-dimensional processes in exoplanetary atmospheres. For instance, in 2020, Ehrenreich et al. reported transmission spectra fro…
The Pandora SmallSat: Multiwavelength Characterization of Exoplanets and their Host Stars
Elisa V. Quintana, Knicole D. Colón, Gregory Mosby +24
Pandora is a SmallSat mission designed to study the atmospheres of exoplanets, and was selected as part of NASA's Astrophysics Pioneers Program. Transmission spectroscopy of transi…
