The formation of (very) slowly rotating stars
H. C. Spruit
The slow rotation of some young stars and the extreme rotation periods of some Ap stars have so far defied explanation. The absence of sufficiently efficient braking mechanisms for…
Disruption of a planet spiralling into its host star
Shi Jia, H. C. Spruit
The processes leading deformation and destruction of planets spiraling into the convective envelope of their host stars are described. The planet is compressed by the ram pressure,…
Instability of mass transfer in a planet-star system
Shi Jia, H. C. Spruit
We show that the angular momentum exchange mechanism governing the evolution of mass transferring binary stars does not apply to Roche-lobe filling planets, because most of the ang…
Small-scale dynamos on the solar surface: dependence on magnetic Prandtl number
I. Thaler, H. C. Spruit
The question of possible small-scale dynamo action in the surface layers of the Sun is revisited with realistic 3D MHD simulations. As in other MHD problems, dynamo action is found…
Overshooting by differential heating
R. Andrássy, H. C. Spruit
On the long nuclear time scale of stellar main-sequence evolution, even weak mixing processes can become relevant for redistributing chemical species in a star. We investigate a pr…
The brightness of magnetic field concentrations in the quiet Sun
R. S. Schnerr, H. C. Spruit
In addition to the `facular' brightening of active regions, the quiet Sun also contains a small scale magnetic field with associated brightenings in continuum radiation. We measure…
