Evolution of Young Neutron Star Envelopes
P. Chang, L. Bildsten
We extend our initial study of diffusive nuclear burning (DNB) for neutron stars (NSs) with Hydrogen atmospheres and an underlying layer of proton capturing nuclei. Our initial stu…
Unstable Nonradial Oscillations on Helium Burning Neutron Stars
Anthony L. Piro, Lars Bildsten
Material accreted onto a neutron star can stably burn in steady state only when the accretion rate is high (typically super-Eddington) or if a large flux from the neutron star crus…
Periodic Thermonuclear X-ray Bursts from GS 1826-24 and the Fuel Composition as a Function of Accretion Rate
D. K. Galloway, A. Cumming, E. Kuulkers +3
We analyze 24 type I X-ray bursts from GS 1826-24 observed by the Rossi X-ray Timing Explorer between 1997 November and 2002 July. The bursts observed between 1997-98 were consiste…
Measuring White Dwarf Accretion Rates via their Effective Temperatures
Dean M. Townsley, Lars Bildsten
Our previous theoretical study of the impact of an accreting envelope on the thermal state of an underlying white dwarf (WD) has yielded equilibrium core temperatures, classical no…
White Dwarf Donors in Ultracompact Binaries: The Stellar Structure of Finite Entropy Objects
Christopher J. Deloye, Lars Bildsten
We discuss the mass-radius (M-R) relations for low-mass (M<0.1 Msun) white dwarfs (WDs) of arbitrary degeneracy and evolved (He, C, O) composition. We do so with both a simple anal…
Theoretical Modeling of the Thermal State of Accreting White Dwarfs Undergoing Classical Novae
Dean M. Townsley, Lars Bildsten
White dwarfs experience a thermal renaissance when they receive mass from a stellar companion in a binary. For accretion rates < 10^-8 Msun/yr, the freshly accumulated hydrogen/hel…
