The influence of accretion rate and metallicity on thermonuclear bursts: predictions from KEPLER models
Nathanael Lampe, Alexander Heger, Duncan K. Galloway
Using the KEPLER hydrodynamics code, 464 models of thermonuclear X-ray bursters were performed across a range of accretion rates and compositions. We present the library of simulat…
Carbon production on accreting neutron stars in a new regime of stable nuclear burning
L. Keek, A. Heger
Accreting neutron stars exhibit Type I X-ray bursts from both frequent hydrogen/helium flashes as well as rare carbon flashes. The latter (superbursts) ignite in the ashes of the f…
Can direct collapse black holes launch gamma-ray bursts and grow to supermassive black holes?
Tatsuya Matsumoto, Daisuke Nakauchi, Kunihito Ioka +2
The existence of black holes (BHs) of mass ~ 10^{9} M_sun at z > 6 is a big puzzle in astrophysics because even optimistic estimates of the accretion time are insufficient for stel…
Are Models for Core-Collapse Supernova Progenitors Consistent with the Properties of Supernova Remnants?
Daniel J. Patnaude, Shiu-Hang Lee, Patrick O. Slane +4
The recent discovery that the Fe-K line luminosities and energy centroids observed in nearby SNRs are a strong discriminant of both progenitor type and circumstellar environment ha…
The LOFT perspective on neutron star thermonuclear bursts
J. J. M. in 't Zand, D. Altamirano, D. R. Ballantyne +31
This is a White Paper in support of the mission concept of the Large Observatory for X-ray Timing (LOFT), proposed as a medium-sized ESA mission. We discuss the potential of LOFT f…
