Crustal Emission and the Quiescent Spectrum of the Neutron Star in KS 1731-260
Robert E. Rutledge, Lars Bildsten, Edward F. Brown +3
(Abridged). The type-I X-ray bursting low mass X-ray binary KS 1731-260 was recently detected for the first time in quiescence by Wijnands et al., following an approximately 13 yr…
Propagation of thermonuclear flames on rapidly rotating neutron stars: extreme weather during type I X-ray bursts
Anatoly Spitkovsky, Yuri Levin, Greg Ushomirsky
We analyze the global hydrodynamic flow in the ocean of an accreting, rapidly rotating, non-magnetic neutron star in an LMXB during a type I X-ray burst. Our analysis takes into ac…
Time-Variable Emission from Transiently Accreting Neutron Stars In Quiescence due to Deep Crustal Heating
Greg Ushomirsky, Robert E. Rutledge
Transiently accreting neutron stars in quiescence (Lx<10^34 erg/s) have been observed to vary in intensity by factors of few, over timescales of days to years. If the quiescent lum…
