Pulsars with compact companions in close eccentric orbits are unique laboratories for testing general relativity and alternative theories of gravity. Moreover, they are excellent targets for future gr...
Does an Average White Dwarf Have Enough Mass to Prevent an Accretion Disk Tilt?
astrophysics accretion white dwarfs cataclysmic variables
2010/11/16
In a recent publication, we introduce the lift force as a common source to accretion disk
tilt that is likely relevant to accretion disk systems. Lift is generated by slightly different supersonic ga...
Radiative activity of magnetic white dwarf undergoing Lorentz-force-driven torsional vibrations
magnetic white dwarf non-radial pulsations magneto-dipole emission
2010/11/11
We study radiative activity of magnetic white dwarf undergoing torsional vibrations about axis of its own dipole magnetic moment under the action of Lorentz restoring force. It is shown that pulsating...
Old White Dwarf Stars with Some Hydrogen -- Cooling Curves
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
We present theoretical analysis on old white dwarf stars with \emph{some} hydrogen, that possess a mass of surface hydrogen from $1\times10^{-11}M_{\sun}$ to $1\times10^{-7}M_{\sun}$. The evolution of...
Ab initio Stellar Astrophysics: Reliable Modeling of Cool White Dwarf Atmospheres
Solar and Stellar Astrophysics (astro-ph.SR) Materials Science (cond-mat.mtrl-sc)
2010/12/27
Over the last decade {\it ab initio} modeling of material properties has become widespread in diverse fields of research. It has proved to be a powerful tool for predicting various properties of matte...
