UV Spectropolarimetry with Polstar: Massive Star Binary Colliding Winds
Nicole St-Louis, Kenneth Gayley, D. John Hillier +13
The winds of massive stars are important for their direct impact on the interstellar medium, and for their influence on the final state of a star prior to it exploding as a superno…
Ultraviolet Spectropolarimetry with Polstar: Massive Star Binary Colliding Winds
Nicole St-Louis, Kenneth Gayley, Desmond John Hillier +13
As sources of chemical enrichment, ionizing radiation and energetic feedback, massive stars drive the ecology of their host galaxies despite their relative rarity, additionally to…
Ultraviolet Spectropolarimetry:Conservative and Nonconservative Mass Transfer in OB Interacting Binaries
Geraldine J. Peters, Ken Gayley, Richard Ignace +11
One objective of the Polstar spectropolarimetry mission is to characterize the degree of nonconservative mass transfer that occurs at various stages of binary evolution, from the i…
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…
A Multi-observing-technique Study of the Dynamical Evolution of the Viscous Disk around the Be Star CMa
Mohammad R. Ghoreyshi, Alex C. Carciofi, Carol E. Jones +3
The observed emission lines of Be stars originate from a circumstellar Keplerian disk that are generally well explained by the Viscous Decretion Disk model. In an earlier work we p…
Be discs in binary systems: II. Misaligned orbits
Isabelle H. Cyr, Carol E. Jones, Despina Panoglou +2
We use a smoothed particle hydrodynamics (SPH) code to examine the effects of misaligned binary companions on Be star discs. We systematically vary the degree of misalignment betwe…
Be discs in binary systems I. Coplanar orbits
Despina Panoglou, Alex C. Carciofi, Rodrigo G. Vieira +4
Be stars are surrounded by outflowing circumstellar matter structured in the form of decretion discs. They are often members of binary systems, where it is expected that the decret…
On the Intrinsic Continuum Linear Polarization of Classical Be Stars: The Effects of Metallicity and One-Armed Density Perturbations
Robbie J. Halonen, Carol E. Jones
We report on the effects of two disk properties on the continuum linear polarization signature of classical Be stars. First, we investigate the effect of including metallicity in c…
On the Intrinsic Continuum Linear Polarization of Classical Be Stars during Disk Growth and Dissipation
Robbie J. Halonen, Carol E. Jones
We investigate the intrinsic continuum linear polarization from axisymmetric density distributions of gas surrounding classical Be stars during the formation and dissipation of the…
The Effect of Density on the Thermal Structure of Gravitationally-Darkened Be Star Disks
M. A. McGill, T. A. A. Sigut, C. E. Jones
The effects of gravitational darkening on the thermal structure of Be star disks of differing densities are systematically examined. Gravitational darkening is the decrease of the…
VLTI/MIDI observations of 7 classical Be stars
Anthony Meilland, Philippe Stee, Olivier Chesneau +1
We measured the mid-infrared extension of the gaseous disk surrounding seven Be stars in order to constrain the geometry of their circumstellar environments and to try to infer phy…
