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…
High-spatial-resolution simulations of Be star disks in binary systems: I. Structure and kinematics of coplanar disks
A. C. Rubio, A. C. Carciofi, J. E. Bjorkman +5
Binarity in massive stars has proven to be an important aspect in the their evolution. For Be stars, it might be the cause of their spin up, and thus part of the mechanism behind t…
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…
Investigating Kozai-Lidov Oscillations and Disc Tearing in Be Star Discs
M. W. Suffak, C. E. Jones, A. C. Carciofi
Recent simulations of Be stars in misaligned binary systems have revealed that misalignment between the disc and binary orbit can cause the disc to undergo Kozai-Lidov (KL) oscilla…
Evolution of the disk in the Be binary Scorpii probed during three periastron passages
R. G. Rast, C. E. Jones, A. C. Carciofi +4
We examine the evolution of the disk surrounding the Be star in the highly eccentric binary system Scorpii over its three most recent periastron passages. -band and ph…
Disc Tearing in a Be Star: Predicted 3D Observations
M. W. Suffak, C. E. Jones, A. C. Carciofi
We build on our previous work involving smoothed particle hydrodynamic simulations of Be stars, by using the model that exhibited disc tearing as input into the three-dimensional M…
Bayesian sampling with BeAtlas, a grid of synthetic Be star spectra I. Recovering the fundamental parameters of αEri and βCMi
A. C. Rubio, A. C. Carciofi, P. Ticiani +14
Classical Be stars are fast rotating, near main sequence B-type stars. The rotation and the presence of circumstellar discs profoundly modify the observables of active Be stars. Ou…
Non-LTE Monte Carlo Radiative Transfer. III. The thermal properties of Tilted and Warped Be Star Discs
M. W. Suffak, C. E. Jones, A. C. Carciofi +1
We use the three-dimensional Monte Carlo radiative transfer code HDUST to model Be stars where the disc is tilted from the equatorial plane of the star. We compute 128 models acros…
Strong Variability in AzV 493, an Extreme Oe-Type Star in the SMC
M. S. Oey, N. Castro, M. Renzo +11
We present 18 years of OGLE photometry together with spectra obtained over 12 years, revealing that the early Oe star AzV 493 shows strong photometric (Delta I < 1.2 mag) and spect…
Ultraviolet Spectropolarimetry: on the origin of rapidly rotating B stars
C. E. Jones, J. Labadie-Bartz, D. V. Cotton +12
UV spectroscopy and spectropolarimetry hold the key to understanding certain aspects of massive stars that are largely inaccessible with optical or longer wavelength observations.…
Growth and Dissipation of Be Star Discs in Misaligned Binary Systems
M. Suffak, C. E. Jones, A. C. Carciofi
We use a three-dimensional smoothed particle hydrodynamics code to simulate growth and dissipation of Be star discs in systems where the binary orbit is misaligned with respect to…
The Large Scale Behaviour in the Disk of Scorpii from 2000-2018
M. W. Suffak, C. E. Jones, C. Tycner +4
We model the circumstellar disk of Sco using the 3-dimensional Monte Carlo radiative transfer code HDUST in order to quantify the large scale changes in the disk through the ye…
SU(3) Clebsch-Gordan coefficients and some of their symmetries
Alex Clesio Nunes Martins, Mark W. Suffak, Hubert de Guise
We discuss the construction and symmetries of su(3) Clebsch-Gordan coefficients arising from the su(3) basis states constructed as triple tensor products of two-dimensional harmoni…
