Applications of a Gaussian Process Framework for Modelling of High-Resolution Exoplanet Spectra
Annabella Meech, Suzanne Aigrain, Matteo Brogi +1
Observations of exoplanet atmospheres in high resolution have the potential to resolve individual planetary absorption lines, despite the issues associated with ground-based observ…
One year of AU Mic with HARPS: II -- stellar activity and star-planet interaction
Baptiste Klein, Norbert Zicher, Robert D. Kavanagh +8
We present a spectroscopic analysis of a 1-year intensive monitoring campaign of the 22-Myr old planet-hosting M dwarf AU Mic using the HARPS spectrograph. In a companion paper, we…
One year of AU Mic with HARPS: I -- measuring the masses of the two transiting planets
Norbert Zicher, Oscar Barragán, Baptiste Klein +11
The system of two transiting Neptune-sized planets around the bright, young M-dwarf AU Mic provides a unique opportunity to test models of planet formation, early evolution, and st…
Planet Hunters TESS IV: A massive, compact hierarchical triple star system TIC 470710327
Nora L. Eisner, Cole Johnston, Silvia Toonen +37
We report the discovery and analysis of a massive, compact, hierarchical triple system (TIC 470710327) initially identified by citizen scientists in data obtained by NASA's Transit…
The EXPRES Stellar Signals Project II. State of the Field in Disentangling Photospheric Velocities
Lily L. Zhao, Debra A. Fischer, Eric B. Ford +40
Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precisi…
