Vanadium oxide and a sharp onset of cold-trapping on a giant exoplanet
Stefan Pelletier, Björn Benneke, Mohamad Ali-Dib +15
The abundance of refractory elements in giant planets can provide key insights into their formation histories. Due to the Solar System giants' low temperatures, refractory elements…
: a data-driven approach to correct for systematics in RV data -- Application to SPIRou data of the planet-hosting M dwarf GJ 251
M. Ould-Elhkim, C. Moutou, J-F. Donati +18
Context: Recent advances in the development of precise radial velocity (RV) instruments in the near-infrared (nIR) domain, such as SPIRou, have facilitated the study of M-type star…
Unsigned magnetic flux proxy from solar optical intensity spectra
F. Lienhard, A. Mortier, H. M. Cegla +3
The photospheric unsigned magnetic flux has been shown to be highly correlated with radial velocity (RV) variations caused by solar surface activity. This activity indicator is the…
Revisiting K2-233 spectroscopic time-series with multidimensional Gaussian Processes
Oscar Barragán, Edward Gillen, Suzanne Aigrain +7
Detecting planetary signatures in radial velocity time-series of young stars is challenging due to their inherently strong stellar activity. However, it is possible to learn inform…
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…
