Detailed study of HD 219134: a benchmark K-dwarf with a compact planetary system
Jérôme Bétrisey, Camilla Pezzotti, Gaël Buldgen +4
Space missions such as CoRoT, Kepler, and TESS have transformed asteroseismology and its synergies with exoplanet science. We revisit the nearby K-dwarf HD 219134 to investigate th…
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…
Constraints on planetary tidal dissipation from a detailed study of Kepler 91b
L. Fellay, C. Pezzotti, G. Buldgen +2
Context. With the detection of thousands of exoplanets, characterising their dynamical evolution in detail represents a key step in the understanding of their formation. Studying t…
Coralie radial-velocity search for companions around evolved stars (CASCADES) III. A new Jupiter host-star: in-depth analysis of HD 29399 using TESS data
C. Pezzotti, G. Ottoni, G. Buldgen +11
Context. Increasing the number of detected exoplanets is far from anecdotal, especially for long-period planets that require a long duration of observation. More detections imply a…
CORALIE radial-velocity search for companions around evolved stars (CASCADES). I. Sample definition and first results: Three new planets orbiting giant stars
G. Ottoni, S. Udry, D. Ségransan +11
Context. Following the first discovery of a planet orbiting a giant star in 2002, we started the CORALIE radial-velocity search for companions around evolved stars (CASCADES). We p…
Kepler-93: a testbed for detailed seismic modelling and orbital evolution of super-earths around solar-like stars
J. Bétrisey, C. Pezzotti, G. Buldgen +4
The advent of space-based photometry missions such as CoRoT, Kepler and TESS has sparkled the development of asteroseismology and exoplanetology. The advent of PLATO will further s…
The key impact of the host star's rotational history on the evolution of TOI-849b
C. Pezzotti, O. Attia, P. Eggenberger +2
TOI-849b is one of the few planets populating the hot-Neptune desert and it is the densest Neptune-sized one discovered so far. Its extraordinary proximity to the host star, togeth…
Star-planet interactions VI. Tides, stellar activity and planet evaporation
Suvrat Rao, Camilla Pezzotti, Georges Meynet +6
Tidal interactions and planet evaporation processes impact the evolution of close-in star-planet systems. We study the impact of stellar rotation on these processes. We compute the…
Revisiting Kepler-444. II. Rotational, orbital and high-energy fluxes evolution of the system
C. Pezzotti, P. Eggenberger, G. Buldgen +3
Context. Kepler-444 is one of the oldest planetary systems known thus far. Its peculiar configuration consisting of five sub-Earth-sized planets orbiting the companion to a binary…
