Exploring the binary origin of B and Be rapid rotators
Jonathan Labadie-Bartz, Mark Suffak, Carol Jones +8
Observational evidence has continued to mount that a significant fraction of rapidly rotating early-B type stars are products of binary mass transfer. However, very few mid- and la…
Predicted observational effects of rapid rotation for Be stars
Rina G. Rast, Carol E. Jones, Mark W. Suffak +6
We conduct a systematic study on the effects of rapid rotation on predicted Be star observables. We use the three-dimensional Monte Carlo radiative transfer code, \textsc{hdust}, t…
High energy emission powered by accreting companions of Be/gamma Cas stars
Rina G. Rast, Yael Naze, Jonathan Labadie-Bartz +6
The origin of the hard, bright X-ray emission that defines the gamma Cas analog class of Be stars remains an outstanding question in Be star literature. This work explores the poss…
Efficiency of viscous angular momentum transport in dissipating Be binaries
Peter Quigley, Carol E. Jones, Kenneth Gayley +9
Angular momentum transport is a fundamental process shaping the structure, evolution, and lifespans of stars and disks across a wide range of astrophysical systems. Be stars offer…
Decretion disc evolution and neutron star accretion in short-period eccentric Be/X-ray binaries
R. G. Rast, C. E. Jones, M. W. Suffak +1
We examine Be star discs in highly eccentric Be/X-ray systems. We use a three-dimensional smoothed particle hydrodynamics (SPH) code to model the structure of the Be star disc and…
