CORALIE radial-velocity search for companions around evolved stars (CASCADES) V. Three planetary companions and achievable precision
P. Figueira, E. Fontanet, J. P. Faria +9
Aims. We expand the planetary census around massive stellar hosts through a long-term campaign of high-precision radial velocity (RV) measurements on evolved stars. Methods. We ana…
The fate of Earth during the Sun's giant phases: New constraints from ab initio tidal modelling and AGB mass loss
M. Esseldeurs, S. Mathis, L. Decin
The long-term evolution of planetary systems around solar-type stars is governed by the interplay between stellar expansion, tidal interactions, and mass loss during the red giant…
Competition between gravity waves excited by convection and tides in stars that host a companion
M. Esseldeurs, J. Ahuir, L. Amard +2
Asteroseismology has become a powerful tool in stellar astrophysics, offering unprecedented insights into the internal structures and dynamics of stars. It enables precise characte…
Evidence for the Keplerian orbit of a close companion around a giant star
Mats Esseldeurs, Leen Decin, Joris De Ridder +31
Close companions influence stellar evolution through tidal interactions, mass transfer, and mass loss effects. While such companions are detected around young stellar objects, main…
Eppur si eclissa: Eccentric low-mass companions and time-in-dust selection explain long secondary periods
Leen Decin, Owen Vermeulen, Mats Esseldeurs +5
[abbreviated] Long Secondary Periods (LSPs) are observed in about one third of pulsating red giants yet remain unexplained. Four key observational constraints anchor the discussion…
ATOMIUM: Continuum emission and evidence of dust enhancement from binary motion
T. Danilovich, N. Samaratunge, Y. Mori +35
Low- and intermediate-mass stars on the asymptotic giant branch (AGB) account for a significant portion of the dust and chemical enrichment in their host galaxy. Here we present AL…
