BRITEning up the Be Phenomenon
D. Baade, Th. Rivinius, A. Pigulski +13
Observations of 25 Ori much expand the picture derived of other early-type Be stars with BRITE and SMEI. Two instead of one difference frequencies rule the variability: (a) The low…
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…
Outbursts and Disk Variability in Be Stars
Jonathan Labadie-Bartz, S. Drew Chojnowski, David G. Whelan +16
In order to study the growth and evolution of circumstellar disks around classical Be stars, we analyze optical time-series photometry from the KELT survey with simultaneous infrar…
The viscous disk properties of 80 Be stars
Rodrigo G. Vieira, Alex C. Carciofi
We investigated the properties of Be star disks, using the time dependent viscous decretion disk (VDD) model to interpret their mid-infrared continuum fluxes. Besides estimati…
The life cycles of Be viscous decretion discs: time-dependent modelling of infrared continuum observations
Rodrigo G. Vieira, Alex C. Carciofi, Jon E. Bjorkman +3
We apply the viscous decretion disc (VDD) model to interpret the infrared disc continuum emission of 80 Be stars observed in different epochs. In this way, we determined 169 specif…
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 coplanar circular binaries: Phase-locked variations of emission lines
Despina Panoglou, Daniel M. Faes, Alex C. Carciofi +4
The first results of radiative transfer calculations on decretion discs of binary Be stars are presented. A smoothed particle hydrodynamics code computes the structure of Be discs…
Revealing the structure of the outer disks of Be stars
R. Klement, A. C. Carciofi, T. Rivinius +9
Context. The structure of the inner parts of Be star disks (20 stellar radii) is well explained by the viscous decretion disk (VDD) model, which is able to reproduce the observable…
The viscous decretion disk model of the classical Be star CMi revisited
Robert Klement, Alex Cavalieri Carciofi, Thomas Rivinius
We revisit the viscous decretion disk (VDD) model of the classical Be star CMi as presented by \citet{klement} using an updated version of the radiative transfer code {\ttfamil…
Science cases for a visible interferometer
Philippe Stee, France Allard, Myriam Benisty +54
High spatial resolution is the key for the understanding various astrophysical phenomena. But even with the future E-ELT, single dish instruments are limited to a spatial resolutio…
VLTI/PIONIER images the Achernar disk swell
G. Dalla Vedova, F. Millour, A. Domiciano de Souza +5
Context. The mechanism of disk formation around fast-rotating Be stars is not well understood. In particular, it is not clear which mechanisms operate, in addition to fast rotation…
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…
A Spectroscopic Orbit for the late-type Be star CMi
Nick Dulaney, Noel D. Richardson, Cody J. Gerhartz +12
The late-type Be star CMi is remarkably stable compared to other Be stars that have been studied. This has led to a realistic model of the outflowing Be disk by Klement et al.…
