Ultraviolet Radiation and Circumstellar Environments
We discuss the nature of the photoevaporating circumstellar disks in the Orion Nebula. The structure of thermally driven neutral and ionized ow from the disks is derived through a simple, spherical model. Evaporation ows are self-regulating, and from the estimated mass loss rates we show that it is possible to estimate the present disk masses. Two-dimensional eeects are discussed qualitatively ...
متن کاملPulsations in red supergiants with high L/M ratio Implications for the stellar and circumstellar structure of supernova progenitors
We investigate the pulsational properties of RSG models – which we evolve from ZAMS masses in the range 10 to 20M – by means of linear and non-linear calculations. We find period and growth rate of the dominant fundamental mode to increase with increasing luminosity-to-mass ratio L/M . Our models obtain relatively large L/M values due to the inclusion of rotation in the evolutionary calculation...
متن کاملProjection of circumstellar disks on their environments
We use a 3D Monte Carlo radiative transfer code to study the projection of large shadows by circumstellar disks around young stellar objects on surrounding reflection nebulosity. It is shown that for a wide range of parameters a small (10−100 AU) circumstellar disk can project a large (1000−10 000 AU) dark band in the near-infrared that often resembles a massive edge-on disk. The disk shadows a...
متن کاملObservational investigation of mass loss of M supergiants
We present the analysis of infrared photometry and millimeter spectroscopy of a sample of 74 late-type supergiants. These observations are particularly suitable to study the mass loss and the circumstellar envelopes of evolved massive stars. In particular, we quantify the circumstellar infrared excess, the relation of mass loss with stellar properties, using the K-[12] colour index as mass-loss...
متن کاملOrigin and Evolution of Dust in Circumstellar and Interstellar Environments
Astronomical observations and analysis of stardust isolated from meteorites have revealed a highly diverse interstellar and circumstellar grain inventory, including both amorphous materials and highly crystalline compounds (oxides, silicates and carbonaceous). This dust is highly processed during its sojourn from its birthsite (stellar outflows and supernova explosions) to its incorporation int...
