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…
The Role of Disk Tearing and Precession in the Observed Variability of Pleione
Keegan C. Marr, Carol E. Jones, Chris Tycner +2
We acquired H spectroscopic observations from 2005 to 2019 showing Pleione has transitioned from a Be phase to a Be-shell phase during this period. Using the radiative transfer…
Dynamical parallax, physical parameters and evolutionary status of the components of the bright eclipsing binary α Draconis
K. Pavlovski, C. A. Hummel, A. Tkachenko +13
Altough both components of the bright eclipsing binary Dra having been resolved using long baseline interferometry and the secondary component shown to contribute some 15\% of…
Surveying the Bright Stars by Optical Interferometry III: A Magnitude-Limited Multiplicity Survey of Classical Be-Stars
D. J. Hutter, C. Tycner, R. T. Zavala +3
We present the results of a multiplicity survey for a magnitude-limited sample of 31 classical Be stars conducted with the Navy Precision Optical Interferometer and the Mark III St…
Spiral Density Enhancements in Be Binary Systems
Isabelle H. Cyr, Carol E. Jones, Alex C. Carciofi +3
We use a smoothed particle hydrodynamics (SPH) code to examine the effects of a binary companion on a Be star disk for a range of disk viscosities and misalignment angles, i.e. the…
Stellar Inclination Angles from Be Star H Emission-Line Profiles
T. A. A. Sigut, A. K. Mahjour, C. Tycner
We demonstrate that the angle between star's rotation axis and the observer's line-of-sight, usually called the inclination angle, can be reliably determined for Be stars via H…
