What happened to the other Mohicans? Realistic models of metallicity dilution by fingering convection and observational implications
hydrodynamics instabilities turbulence planets and satellites
2010/11/16
When a planet falls onto the surface of its host star, the added high-metallicity material does not remain in the surface layers, as often assumed, but is diluted into the interior through fingering (...
Relaxing the Small Particle Approximation for Dust-grain opacities in Carbon-star Wind Models
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
We have computed wind models with time-dependent dust formation and grain-size dependent opacities, where (1) the problem is simplified by assuming a fixed dust-grain size, and where (2) the radiation...
