Our observations indicate that super-Chandrasekhar-mass white-dwarf mergers can avoid thermonuclear explosion as type Ia supernovae, and provide evidence of the generation of magnetic fields in stellar mergers.This is a preview of subscription content, access via your institution ...
and they are also detectable at radio frequencies. They reflect the spin of a magnetic white dwarf, which we find to be slowing down on a 107-year timescale. The spin-down power is an order of magnitude larger than that seen in electromagnetic radiation, which, together with an absence of...

So maybe they have accounting legal issues that dwarf the vast majority of the software houses I do business with. Okay. Yet, no one else manages to ask for a monthly subscription. You could charge each quarter as an option with a reasonable update cost– say, $10, or $25 per app. ...
3 White Dwarf models 3.1 Hydrostatic structure in alternative coupling gravity We model the WD as a static, spherically symmetric star. The star is assumed to be in the hydrostatic equilibrium, which satisfies ∇Φ = − 1 ρ ∇ p. Applying this to Eq. (8), using the EiBI notation,...
In this work, we present the relevant white dwarf cooling limits over the entire A′ mass range. In particular, we have performed a rigorous computation of the luminosities in the resonant regime, where the A′ mass is comparable to the white dwarf plasma frequencies. Keywords: New Gauge ...

White dwarf and pre-white dwarfs are the best types of stars for the application of Stark broadening research results in astrophysics, since in the atmospheres of these stars physical conditions are very favorable for this line broadening mechanism - in
propertiesof the stellar structure. This method therefore is a very valuable toolto test stellar evolution models.In principle, pulsatingwhite dwarfs andΒ subdwarf stars (sdB)are ideal seismological objects since they exhibit several excitedmodes. In the case of white dwarfs, the pulsations are ...
