Continuous mass ablation of planets engulfed in stellar envelopes
Mike Y. M. Lau, Robert Andrassy, Giovanni Leidi +4
Most stars host short-period planets that are expected to be engulfed during post-main-sequence expansion. The dissolution of engulfed planets has been proposed as a possible mecha…
Convective settling in main sequence stars: Li and Be depletion
R. Andrássy, H. C. Spruit
The process of convective settling is based on the assumption that a small fraction of the low-entropy downflows sink from the photosphere down to the bottom of the star's envelope…
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…
Overshooting by convective settling
R. Andrássy, H. C. Spruit
We study a process of slow mixing in stars with convective envelopes, which is driven by the settling of cool downward plumes below the base of the convection zone. If a small frac…
