Unraveling the Mystery of the Peculiar and Young Hot Jupiter CoRoT-2b. I. HO and CO Detection from Dayside Observations with Gemini-S/IGRINS
Ying Shu, Lisa Dang, Antoine Darveau-Bernier +12
We present ground-based high-resolution spectroscopic pre-eclipse observations of the hot Jupiter CoRoT-2b obtained with the IGRINS spectrograph on Gemini South. Using cross-correl…
A window for water-hydrogen demixing on warm metal-rich sub-Neptunes
Caroline Piaulet-Ghorayeb, Daniel P. Thorngren, Eliza M. -R. Kempton +4
Sub-Neptunes represent the largest exoplanet demographic, yet their bulk compositions remain poorly understood. Recent studies suggested that only very cold planets, such as Uranus…
Super-Earth masses and stellar abundances from NIRPS reveal tentative evidence for water-rich formation around M dwarfs
Drew Weisserman, Nicole Gromek, Ryan Cloutier +98
Tracing the compositional link between terrestrial super-Earths and their host stars provides clues to their dominant formation pathway. By constraining the stellar abundances of r…
Blind search for activity-sensitive lines in the near-infrared using HARPS and NIRPS observations of Proxima and Gl 581
João Gomes da Silva, Elisa Delgado-Mena, Nuno C. Santos +145
Stellar activity variability is one of the main obstacles to the detection of Earth-like planets using the RV method. The aim of this work is to measure the effect of activity in t…
