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…
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-…
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…
X-Raying a Be star disk: fundamental parameters of the eclipsing binary Be star V658 Car
Tajan H. de Amorim, Alex C. Carciofi, Jonathan Labadie-Bartz +8
With its two stellar eclipses and two disk attenuations per binary orbit, V658 Carinae stands out as the first clear eclipsing Be + sdOB system. This rare alignment offers a unique…
Exploring membership and variability in NGC 7419: An open cluster rich in super giants and Be type stars
Arghya Chakraborty, Jessy Jose, Alex C. Carciofi
NGC 7419 is a young open cluster notable for hosting five Red Supergiants and a high abundance of Classical Be (CBe) stars. CBe stars are main sequence non-supergiant B-type stars,…
