Is planetary inward migration responsible for GJ 504's fast rotation and bright X-ray luminosity? New constraints from eROSITA
C. Pezzotti, G. Buldgen, E. Magaudda +4
The discovery of an increasing variety of exoplanets in very close orbits around their host stars raised many questions about how stars and planets interact, and to which extent ho…
Radio Signatures of Star-Planet Interactions, Exoplanets, and Space Weather
J. R. Callingham, B. J. S. Pope, R. D. Kavanagh +22
Radio detections of stellar systems provide a window onto stellar magnetic activity and the space weather conditions of extrasolar planets, information that is difficult to attain…
Spectropolarimetric characterisation of exoplanet host stars in preparation of the Ariel mission. Magnetic environment of HD 63433
S. Bellotti, D. Evensberget, A. A. Vidotto +8
The accurate characterisation of the stellar magnetism of planetary host stars has been gaining momentum, especially in the context of transmission spectroscopy investigations of e…
Characterizing planetary systems with SPIRou: M-dwarf planet-search survey and the multiplanet systems GJ 876 and GJ 1148
C. Moutou, X. Delfosse, A. C. Petit +18
SPIRou is a near-infrared spectropolarimeter and a high-precision velocimeter. The SPIRou Legacy Survey collected data from February 2019 to June 2022, half of the time devoted to…
TOI-1759 b: a transiting sub-Neptune around a low mass star characterized with SPIRou and TESS
Eder Martioli, Guillaume Hébrard, Pascal Fouqué +57
We report the detection and characterization of the transiting sub-Neptune TOI-1759 b, using photometric time-series from TESS and near infrared spectropolarimetric data from SPIRo…
Mitigating stellar activity jitter with different line lists for least-squares deconvolution: analysis of a parametric and a randomised line selection
Stefano Bellotti, Pascal Petit, Julien Morin +5
Stellar activity limits the radial velocity search and characterisation of exoplanets, as it introduces spurious jitter in the data sets and prevents the correct retrieval of a pla…
