The birth of Be star disks III. SPH models of localised mass ejections
A. C. Rubio, A. C. Carciofi, D. Baade +4
Classical Be stars exhibit mass ejection events that feed their viscous decretion disks. Recent TESS space photometry and simultaneous spectroscopy revealed that these flickers are…
Constraints on Binarity for the Extreme Oe Variable Star AzV 493
M. S. Oey, Irene Vargas-Salazar, Edmund Hodges-Kluck +6
The extreme Oe star AzV 493 is known to show unusual photometric and spectroscopic variability that suggest the presence of an unseen companion in a highly eccentric and long-perio…
Dynamical Masses and Radiative Transfer Modeling of HD 698: a Be Binary in Evolutionary Transition
Ilfa A. Gabitova, Alex C. Carciofi, Tajan H. de Amorim +13
We present a detailed analysis of the early post-mass-transfer binary HD 698 (V742 Cas) combining high-resolution optical spectroscopy, long-baseline interferometry, and radiative-…
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…
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…
