Star-planet interactions. V. Dynamical and equilibrium tides in convective zones

Suvrat Rao, Georges Meynet, Patrick Eggenberger +5

When planets are formed from the protoplanetary disk and after the disk has dissipated, the evolution of their orbits is governed by tidal interactions, friction, and gravitational…

Star-planet interactions. IV. Possibility of detecting the orbit-shrinking of a planet around a red giant

Georges Meynet, Patrick Eggenberger, Giovanni Privitera +4

The surface rotations of some red giants are so fast that they must have been spun up by tidal interaction with a close companion, either another star, a brown dwarf, or a planet.…

High surface magnetic field in red giants as a new signature of planet engulfment?

Giovanni Privitera, Georges Meynet, Patrick Eggenberger +6

Context. Red-giant stars may engulf planets. This may increase the rotation rate of their convective envelope, which could lead to strong dynamo-triggered magnetic fields. Aims. We…

Star-planet interactions: II. Is planet engulfment the origin of fast rotating red giants?

Giovanni Privitera, Georges Meynet, Patrick Eggenberger +3

Context. Fast rotating red giants in the upper part of the red giant branch have surface velocities that cannot be explained by single star evolution. Aims. We check whether tides…

Star-planet interactions: I. Stellar rotation and planetary orbits

Giovanni Privitera, Georges Meynet, Patrick Eggenberger +3

Context. As a star evolves, the planet orbits change with time due to tidal interactions, stellar mass losses, friction and gravitational drag forces, mass accretion and evaporatio…

Impact of rotation on stellar models

Georges Meynet, Andre Maeder, Patrick Eggenberger +5

After a brief recall of the main impacts of stellar rotation on the structure and the evolution of stars, four topics are addressed: 1) the links between magnetic fields and rotati…

Non-detection of magnetic fields in the central stars of the planetary nebulae NGC 1360 and LSS 1362

F. Leone, M. J. Martinez Gonzalez, R. L. M. Corradi +2

The presence of magnetic fields is an attractive hypothesis for shaping PNe. We report on observations of the central star of the two Planetary Nebulae NGC1360 and LSS1326. We perf…
