Fast and Slow Crystallization-driven Convection in White Dwarfs

The Astrophysical Journal
We investigate crystallization-driven convection in carbon–oxygen white dwarfs. We present a version of the mixing length theory that self-consistently includes the effects of thermal diffusion and composition gradients, and provides solutions for the ...

The mass-radius relationship from solar-type stars to terrestrial planets: a review

, 2008
In this review, we summarize our present knowledge of the behaviour of the mass-radius relationship from solar-type stars down to terrestrial planets, across the regime of substellar objects, brown dwarfs and giant planets.

Zones of Tayler Instability in Stars

The Astrophysical Journal
The Tayler instability (TI) of toroidal magnetic fields is a candidate mechanism for driving turbulence, angular momentum (AM) transport, and dynamo action in stellar radiative zones. Recently V. A. Skoutnev & A. M.

Is the Plasma Within Bubbles and Superbubbles Hot or Cold? [PDF]

, 1999
I review what is known about the temperature of the plasma within stellar wind bubbles and superbubbles. Classical theory suggests that it should be hot, with characteristic temperatures of order a million degrees.

Turbulent convection in stellar interiors. III. Mean-field analysis and stratification effects

, 2013
We present 3D implicit large eddy simulations (ILES) of the turbulent convection in the envelope of a 5 Msun red giant star and in the oxygen-burning shell of a 23 Msun supernova progenitor.

2D or not 2D: the effect of dimensionality on the dynamics of fingering convection at low Prandtl number

, 2015
Fingering convection (otherwise known as thermohaline convection) is an instability that occurs in stellar radiative interiors in the presence of unstable compositional gradients.

Stellar structure and compact objects before 1940: Towards relativistic astrophysics

, 2017
Since the mid-1920s, different strands of research used stars as "physics laboratories" for investigating the nature of matter under extreme densities and pressures, impossible to realize on Earth.

Rotation and Stellar Interiors (Review Paper) [PDF]

International Astronomical Union Colloquium, 1970
Research into the effect of rotation on the internal structure of stars has a long and detailed history. The names of McLaurin, Jacobi, Kelvin and Jeans are associated with detailed work on the structure and stability of rotating liquid masses assuming uniform rotation.

A semi-analytic approach to angular momentum transport in stellar radiative interiors

, 2009
We address the problem of angular momentum transport in stellar radiative interiors with a novel semi-analytic spectral technique, using an eigenfunction series expansion, that can be used to derive benchmark solutions in hydromagnetic regimes with very ...
