KIC 7955301: a hierarchical triple system with eclipse timing variations and an oscillating red giant
P. Gaulme, T. Borkovits, T. Appourchaux +13
KIC 7955301 is a hierarchical triple system with eclipse timing and depth variations discovered by the Kepler mission. It is composed of a non-eclipsing primary star at the bottom…
Active red giants: close binaries versus single rapid rotators
Patrick Gaulme, Jason Jackiewicz, Federico Spada +7
The objective of this work is to determine what fraction of red-giant (RG) stars shows photometric rotational modulation, and understand its origin. One of the underlying questions…
Could star-planet magnetic interactions lead to planet migration and influence stellar rotation ?
Jérémy Ahuir, Antoine Strugarek, Allan-Sacha Brun +5
The distribution of hot Jupiters, for which star-planet interactions can be significant, questions the evolution of exosystems. We aim to follow the orbital evolution of a planet a…
Observations of tides and circularization in red-giant binaries from Kepler photometry
P. G. Beck, S. Mathis, T. Kallinger +2
Binary stars are places of complex stellar interactions. While all binaries are in principle converging towards a state of circularization, many eccentric systems are found even in…
Evolution of star-planet systems under magnetic braking and tidal interaction
M. Benbakoura, V. Réville, A. S. Brun +2
With the discovery over the last two decades of a large diversity of exoplanetary systems, it is now of prime importance to characterize star-planet interactions and how such syste…
Testing tidal theory for evolved stars by using red-giant binaries observed by Kepler
P. G. Beck, S. Mathis, F. Gallet +4
Tidal interaction governs the redistribution of angular momentum in close binary stars and planetary systems and determines the systems evolution towards the possible equilibrium s…
