Solar evolution models with a central black hole
Earl P. Bellinger, Matt E. Caplan, Taeho Ryu +6
Hawking (1971) proposed that the Sun may harbor a primordial black hole whose accretion supplies some of the solar luminosity. Such an object would have formed within the first 1 s…
Observational predictions for Thorne-Żytkow objects
R. Farmer, M. Renzo, Y. Götberg +3
Thorne-ytkow objects (TO) are potential end products of the merger of a neutron star with a non-degenerate star. In this work, we have computed the first grid of evolutionary…
Pair-instability mass loss for top-down compact object mass calculations
M. Renzo, D. D. Hendriks, L. A. C. van Son +1
Population synthesis relies on semi-analytic formulae to determine masses of compact objects from the (helium or carbon-oxygen) cores of collapsing stars. Such formulae are combine…
The expansion of stripped-envelope stars: consequences for supernovae and gravitational-wave progenitors
E. Laplace, Y. Götberg, S. E. de Mink +2
Massive binaries that merge as compact objects are the progenitors of gravitational-wave sources. Most of these binaries experience one or more phases of mass transfer, during whic…
Predictions for the hydrogen-free ejecta of pulsational pair-instability supernovae
M. Renzo, R. Farmer, S. Justham +5
Present time-domain astronomy efforts will unveil a variety of rare transients. We focus here on pulsational pair-instability evolution, which can result in signatures observable w…
Modules for Experiments in Stellar Astrophysics (MESA): Pulsating Variable Stars, Rotation, Convective Boundaries, and Energy Conservation
Bill Paxton, R. Smolec, Josiah Schwab +14
We update the capabilities of the open-knowledge software instrument Modules for Experiments in Stellar Astrophysics (MESA). RSP is a new functionality in MESAstar that models the…
