Gravitational waves from rapidly rotating white dwarfs
Rapidly rotating white dwarfs in cataclysmic variable systems may be emitting gravitational radiation due to the recently discovered relativistic rmode instability. Assuming that the four most rapidly rotating known systems are limited in rotation rate by the instability, the amplitude of the emitted gravitational waves is determined at Earth for both known rapid rotators and for a model backgr...
متن کاملMagnetically-driven Explosions of Rapidly-rotating White Dwarfs following Accretion-induced Collapse
We present 2D multi-group flux-limited diffusion magnetohydrodynamics (MHD) simulations of the Accretion-Induced Collapse (AIC) of a rapidly-rotating 1.92M⊙ white dwarf, started from a 2D rotational equilibrium configuration. We focus on determining the dynamical role of MHD processes after the formation of a millisecond-period protoneutron star. We find that, compared with the previous study o...
متن کاملOn the evolution of rapidly rotating massive white dwarfs towards supernovae or collapses
A recent study by Yoon & Langer (2004a) indicated that the inner cores of rapidly accreting (Ṁ > 10−7 M⊙ yr−1) CO white dwarfs may rotate differentially, with a shear rate near the threshold value for the onset of the dynamical shear instability. Such differentially rotating white dwarfs obtain critical masses for thermonuclear explosion or electron-capture induced collapse which significantly ...
متن کاملOff-Center Carbon Ignition in Rapidly Rotating, Accreting Carbon-Oxygen White Dwarfs
We study the effect of stellar rotation on the carbon ignition in a carbonoxygen white dwarf accreting CO-rich matter. Including the effect of the centrifugal force of rotation, we have calculated evolutionary models up to the carbon ignition for various accretion rates. The rotation velocity at the stellar surface is set to be the Keplerian velocity. The angular velocity in the stellar interio...
متن کاملFlaring up All over — Radio Activity in Rapidly-rotating Late M and L Dwarfs
We present Very Large Array observations of twelve late M and L dwarfs in the Solar neighborhood. The observed sources were chosen to cover a wide range of physical characteristics — spectral type, rotation, age, binarity, and X-ray and Hα activity — to determine the role of these properties in the production of radio emission, and hence magnetic fields. Three of the twelve sources, TVLM 513-46...
