Exploring the atmosphere of GJ 1132 b with CRIRES+
E. Palle, F. Yan, G. Morello +8
With a mass, radius, and mean density similar to Earth's, the rocky planet GJ 1132 b is the first truly small planet for which an atmosphere detection was proposed. If confirmed, u…
Planet Mass and Metallicity: The Exoplanets and Solar System Connection
Mark R. Swain, Yasuhiro Hasegawa, Daniel P. Thorngren +1

Comparing transit spectroscopy pipelines at the catalogue level: evidence for systematic differences
Lorenzo V. Mugnai, Mark R. Swain, Raissa Estrela +1
The challenge of inconsistent results from different data pipelines, even when starting from identical data, is a recognized concern in exoplanetary science. As we transition into…
Identification of carbon dioxide in an exoplanet atmosphere
The JWST Transiting Exoplanet Community Early Release Science Team, Eva-Maria Ahrer, Lili Alderson +129
Carbon dioxide (CO2) is a key chemical species that is found in a wide range of planetary atmospheres. In the context of exoplanets, CO2 is an indicator of the metal enrichment (i.…
A Temperature Trend for Clouds and Hazes in Exoplanets Atmospheres
Raissa Estrela, Mark Swain, Gael Roudier
The transmission spectra of exoplanet atmospheres observed with the Hubble Space Telescope (HST) in the near-infrared range (1.1-1.65m) frequently show evidence for some combina…
Characterization of an Instrument Model for Exoplanet Transit Spectrum Estimation through Wide Scale Analysis on HST Data
Noah Huber-Feely, Mark R. Swain, Gael Roudier +1
Instrument models (IMs) enable the reduction of systematic error in transit spectroscopy light curve data, but, since the model formulation can influence the estimation of science…
A unique hot Jupiter spectral sequence with evidence for compositional diversity
Megan Mansfield, Michael R. Line, Jacob L. Bean +11
The emergent spectra of close-in, giant exoplanets ("hot Jupiters") are expected to be distinct from those of self-luminous objects with similar effective temperatures because hot…
Detection of Aerosols at Microbar Pressures in an Exoplanet Atmosphere
Raissa Estrela, Mark Swain, Gael Roudier +3
Formation of hazes at microbar pressures has been explored by theoretical models of exoplanet atmospheres to explain Rayleigh scattering and/or featureless transmission spectra, ho…
Detection of an Atmosphere on a Rocky Exoplanet
Mark R. Swain, Raissa Estrela, Gael M. Roudier +7
We report the detection of an atmosphere on a rocky exoplanet, GJ 1132 b, which is similar to Earth in terms of size and density. The atmospheric transmission spectrum was detected…
