Gamma-ray bursts from X-ray binaries
H. C. Spruit
A weakly magnetized (G) neutron star, slowly spun up by accretion in an X-ray binary, crosses the instability boundary for r-mode instability at P=1--2 msec. The amplitu…
Fast maximum entropy Doppler mapping
H. C. Spruit
A numerical code is described for constructing Doppler maps from the orbital variation of line profiles of (mass transfering) binaries. It uses an algorithm related to Richardson-L…
Why pulsars rotate and move: kicks at birth
H. Spruit, E. S. Phinney
RADIO pulsars are thought to born with spin periods of 0.02-0.5 s and space velocities of 100-1000 km/s, and they are inferred to have initial dipole magnetic fields of 10^{11}-10^…
Origin of the rotation rates of single white dwarfs
H. C. Spruit
I argue that the rotation of white dwarfs is not a remnant of the angular momentum of their main sequence progenitors but a result of the mass loss process on the AGB. Weak magneti…
