SPIN-UP/SPIN-DOWN MODELS FOR TYPE Ia SUPERNOVAE
In the single-degenerate scenario for Type Ia supernovae (SNe Ia), a white dwarf (WD) must gain a significant amount of matter from a companion star. Because the accreted mass carries angular momentum, the WD is likely to achieve fast spin periods, which can increase the critical mass, Mcrit, needed for explosion. When Mcrit is higher than the maximum mass achieved by the WD, the central region...
متن کاملMonopolar Pulsar Spin-Down
A multipole spin-down equation based on a monopolar term is derived from the general expression ν̇ = −f(ν, t) and used to study pulsar evolution. We show that the time-independent version of such equation cannot reproduce the observed properties of pulsars and conclude that there is no equation of the form ν̇ = −f(ν) consistent with the P − Ṗ diagram and braking index measurements. We explore the...
متن کاملMagnetar Spin-Down.
We examine the effects of a relativistic wind on the spin-down of a neutron star and apply our results to the study of soft gamma repeaters (SGRs), which are thought to be neutron stars with magnetic fields greater than 1014 G. We derive a spin-down formula that includes torques from both dipole radiation and episodic or continuous particle winds. We find that if SGR 1806-20 puts out a continuo...
متن کاملOn the spin-down of Be stars
The spin-down of Be stars due to angular momentum transport from star to disc has been considered. This has been prompted by empirical studies of observed optical and IR line profile studies indicating that the disc is rotating in a Keplerian fashion. It is found that substantial spin-down may occur, especially for late B stars throughout their main-sequence lives for the “strongest” discs (mos...
متن کاملAdaptive Disk Spin-Down Algorithms in Practice
Significant research has been done to minimize disk energy consumption with excellent timeout based disk spindown algorithms [1, 3, 4, 5]. However, in practice, performance is limited with such algorithms due to spin-up latency, file-system logging, and page-cache write-back policies. Spin-up latency significantly decreases user interactivity while file-system logging and dirty-page writeback p...
