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…
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…
