Angular Momentum Loss Rates in Be Stars Determined by the Viscous Decretion Disc Model
M. R. Ghoreyshi, C. E. Jones, A. Granada
Circumstellar discs around Be stars are formed by the material ejected by the central star. This process removes excess angular momentum from the star as viscosity facilitates the…
The Be Star 66 Ophiuchi: 60 Years of Disk Evolution
Keegan C. Marr, Carol E. Jones, Alex C. Carciofi +5
We use a time-dependent hydrodynamic code and a non-LTE Monte Carlo code to model disk dissipation for the Be star 66 Ophiuchi. We compiled 63 years of observations from 1957 to 20…
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…
A Multi-technique Study of the Dynamical Evolution of the Viscous Disk around the Be Star ω CMa
Mohammad Reza Ghoreyshi
There is an increasing body of evidence that suggests that Be disks are well described by the Viscous Decretion Disk (VDD) model according to which the formation and structure of t…
The life cycles of Be viscous decretion discs: The case of ω CMa
M. R. Ghoreyshi, A. C. Carciofi, L. R. Rimulo +6
We analyzed V-band photometry of the Be star ω CMa, obtained during the last four decades, during which the star went through four complete cycles of disc formation and dissipation…
The life cycles of Be viscous decretion discs: fundamental disc parameters of 54 SMC Be stars
Leandro Rocha Rímulo, Alex Cavaliéri Carciofi, Rodrigo Georgetti Vieira +7
Be stars are main-sequence massive stars with emission features in their spectrum, which originates in circumstellar gaseous discs. Even though the viscous decretion disc (VDD) mod…
Short-term variability and mass loss in Be stars III. BRITE and SMEI satellite photometry of 28 Cygni
D. Baade, A. Pigulski, Th. Rivinius +11
The BRITE Constellation of nanosatellites obtained mmag photometry of 28 Cygni for 11 months in 2014-2016. Observations with the Solar Mass Ejection Imager in 2003-2010 and 118 H$α…
An analysis of the V-band light curve of the Be star omega CMa with the viscous decretion disk model
Mohammad Reza Ghoreyshi, Alex Cavalieri Carciofi
We analyze the V-band photometry data of the Be star omega CMa, observed during the last four decades. The data is fitted by hydrodynamic models based on the viscous decretion disk…
Modeling the Complete Lightcurve of omega CMa
M. R. Ghoreyshi, A. C. Carciofi, L. R. Rimulo +5
We have used the radiative transfer code HDUST to analyze and interpret the long-term photometric behavior of the Be star omega CMa, considering four complete cycles of disk format…
