Turbulent viscosity in line-driven stellar winds
Matías Montesinos, Michel Cure, Ignacio Araya +1
Radiation-driven winds from massive stars generate powerful outflows known to be intrinsically turbulent. Despite this, standard hydrodynamic models have historically restricted th…
Analytical Solutions for Radiation-Driven Winds in Massive Stars II: The -slow Regime
I. Araya, A. Christen, M. Curé +7
Accurate mass-loss rates and terminal velocities from massive stars winds are essential to obtain synthetic spectra from radiative transfer calculations and to determine the evolut…
A triple star system with a misaligned and warped circumstellar disk shaped by disk tearing
Stefan Kraus, Alexander Kreplin, Alison K. Young +29
Young stars are surrounded by a circumstellar disk of gas and dust, within which planet formation can occur. Gravitational forces in multiple star systems can disrupt the disk. The…
Probing the Inner Disk Emission of the Herbig Ae Stars HD 163296 and HD 190073
Benjamin R. Setterholm, John D. Monnier, Claire L. Davies +16
The physical processes occurring within the inner few astronomical units of proto-planetary disks surrounding Herbig Ae stars are crucial to setting the environment in which the ou…
Co-existence and switching between fast and -slow wind solutions in rapidly rotating massive stars
Ignacio Araya, Michel Curé, Asif ud-Doula +2
Most radiatively-driven massive star winds can be modelled with m-CAK theory resulting in so called fast solution. However, those most rapidly rotating among them, especially when…
Stellar parameters and H line profile variability of Be stars in the BeSOS survey
C. Arcos, S. Kanaan, J. Chávez +3
The Be phenomenon is present in about 20 of the B-type stars. Be stars show variability on a broad range of timescales, which in most cases is related to the presence of a circ…
-Slow Solutions and Be Star Disks
I. Araya, C. E. Jones, M. Curé +4
As the disk formation mechanism(s) in Be stars is(are) as yet unknown, we investigate the role of rapidly rotating radiation-driven winds in this process. We implemented the effect…
Evidence for Different Disk Mass Distributions Between Early and Late-Type Be Stars in the BeSOS Survey
C. Arcos, C. E. Jones, T. A. A. Sigut +2
The circumstellar disk density distributions for a sample of 63 Be southern stars from the BeSOS survey were found by modelling their H emission line profiles. These disk densit…
TYC 8241 2652 1 and the case of the disappearing disk: no smoking gun yet
Hans Moritz Günther, Stefan Kraus, Carl Melis +12
TYC 8241 2652 1 is a young star that showed a strong mid-infrared (mid-IR, 8-25 mu) excess in all observations before 2008 consistent with a dusty disk. Between 2008 and 2010 the m…
Fundamental parameters of the close interacting binary HD170582 and its luminous accretion disc
R. E. Mennickent, G. Djurašević, M. Cabezas +5
We present a spectroscopic and photometric study of the Double Period Variable HD170582. Based on the study of the ASAS V-band light curve we determine an improved orbital period o…
Line-Driven Winds Revisited in the Context of Be Stars: -slow Solutions with High Values
J. Silaj, M. Cure, C. E. Jones
The standard, or fast, solutions of m-CAK line-driven wind theory cannot account for slowly outflowing disks like the ones that surround Be stars. It has been previously shown that…
Analytical Solutions for Radiation-Driven Winds in Massive Stars. I: The Fast Regime
Ignacio Araya, Michel Cure, Lydia S. Cidale
Accurate massloss rate estimates are crucial keys to study wind properties of massive stars and test different evolutionary scenarios. From a theoretical point of view, this implie…
Radial velocity variations in the young eruptive star EX Lup
Á. Kóspál, M. Mohler-Fischer, A. Sicilia-Aguilar +7
EX Lup-type objects (EXors) are low-mass pre-main sequence objects characterized by outbursts attributed to highly enhanced disk accretion. The trigger mechanism of EXor outbursts…
The Slow Winds of A-Type Supergiants
Anahí Granada, Michel Curé, Lydia Cidale
The line driven- and rotation modulated-wind theory predicts an alternative slow solution, besides from the standard m-CAK solution, when the rotational velocity is close to the cr…
Radiation driven winds with rotation: The oblate finite disc correction factor
Ignacio Araya, Michel Curé, Anahí Granada +1
We have incorporated the oblate distortion of the shape of the star due to the stellar rotation, which modifies the finite disk correction factor (f_D) in the m-CAK hydrodynamical…
