[Ne ii] emission line profiles from photoevaporative disc winds
I model profiles of the [Ne ii] forbidden emission line at 12.81μm, emitted by photoevaporative winds from discs around young, solar-mass stars. The predicted line luminosities (∼ 10L⊙) are consistent with recent data, and the line profiles vary significantly with disc inclination. Edge-on discs show broad (30–40 km s−1) double-peaked profiles, due to the rotation of the disc, while in face-on ...
متن کاملStructured, Dynamo Driven Stellar and Disc Winds
Considerable progress has been made in understanding the hydrodynamics, but only to a certain extent the magnetohydrodynamics, of shaping bipolar outflows forming protoplanetary nebulae (PPNs) and planetary nebulae (PNs). In particular, Blackman et al. (2001b,2001a) point out two problems related to the formation of PNs and PPNs, regarding the formation of multipolar structures and the origin o...
متن کاملHydrodynamic Models of Line-Driven Accretion Disk Winds II: Adiabatic Winds from Nonisothermal Disks
We present here numerical hydrodynamic simulations of line-driven accretion disk winds in cataclysmic variable systems. We calculate wind mass-loss rate, terminal velocities, and line profiles for C IV (1550 Å) for various viewing angles. The models are 2.5-dimensional, include an energy balance condition, and calculate the radiation field as a function of position near an optically thick accre...
متن کاملModels of Forbidden Line Emission Profiles from Axisymmetric Stellar Winds
A number of strong infrared forbidden lines have been observed in several evolved Wolf-Rayet star winds, and these are important for deriving metal abundances and testing stellar evolution models. In addition, because these optically thin lines form at large radius in the wind, their resolved profiles carry an imprint of the asymptotic structure of the wind flow. This work presents model forbid...
متن کاملTurbulence in Line-Driven Stellar Winds
Hot, luminous OB stars have strong stellar winds driven by the line-scattering of the star's continuum radiation. This line-driving mechanism is understood to be highly unstable to smallscale perturbations. I review e orts to simulate the nonlinear evolution of this instability using radiation hydrodynamics simulation codes. Because the usual local, Sobolev treatment for the line-force does not...
