The atomic C/O ratio of KELT-9b

Stefan Pelletier, Nicholas W. Borsato, Jacob L. Bean +12

The carbon-to-oxygen (C/O) ratio of a giant planet's atmosphere has long been theorised to hold compositional information that can be traced back to its formation history. Typicall…

Sorting a mess I: Addressing velocity-axis correlation of cross-correlation functions. A census of atomic and ionised species in KELT-9b's atmosphere

Nicholas W. Borsato, Brian Thorsbro, Jens Hoeijmakers +3

Ultra-hot Jupiters (UHJs) are the most extreme class of close-in gas giants. We combine 13 transit observations of KELT-9b from six high-resolution spectrographs spanning 316-960 n…

The future of high-resolution UV spectroscopy: Science with a UV Échelle spectrograph on the Habitable Worlds Observatory, or a dedicated mission

Annalisa De Cia, David Cont, Kevin Heng +39

High-resolution UV spectroscopy serves a diversity of science cases, from small bodies to planets, stars, and galaxies, but is currently limited to the Hubble Space Telescope and b…

Hot Rocks Survey IV: Emission from LTT 3780 b is consistent with a bare rock

Natalie H. Allen, Néstor Espinoza, Hannah Diamond-Lowe +19

It is an open question whether small planets around M dwarfs are able to maintain atmospheres. The Hot Rocks Survey aims to address this question by observing 9 rocky exoplanets or…
