Spectral study of MWC 560 . Parameters of the system , the hot source and the jets
Results of spectroscopy of unusual symbiotic variable star MWC560 are presented. The data have been obtained from autumn 1990 to spring 1993. High velocity absorption lines of H I, D1 D2 Na I, Fe II(42) and He I are permanently presented in the spectra, their radial velocity is −500 ÷ −2500 km/s and is changed with a time–scale of a few months. The high velocity absorption line profiles demonst...
متن کاملMultiplicity of Nova Envelope Solutions and Occurrence of Optically Thick Winds
We revisit the occurrence condition of optically thick winds reported by Kato (1985) and Kato & Hachisu (1989) who examined mathematically nova envelope solutions with an old opacity and found that optically thick winds are accelerated only in massive white dwarfs (WDs) of & 0.9 M⊙. With the OPAL opacity we find that the optically thick wind occurs for & 0.6 M⊙ WDs and that the occurrence of wi...
متن کاملDetection of X - rays from the jet - driving Symbiotic Star MWC 560
Aims. We report the detection of X-ray emission from the jet-driving symbiotic star MWC 560. Methods. We observed MWC 560 with XMM-Newton for 36 ks. We fitted the spectra from the EPIC pn, MOS1 and MOS2 instruments with XSPEC and examined the light curves with the package XRONOS. Results. The spectrum can be fitted with a highly absorbed hard X-ray component from an optically-thin hot plasma, a...
متن کاملBlackbody Radiation in Optically Thick Gases?
In this work, the claim that optically thick gases can emit as blackbodies is refuted. The belief that such behavior exists results from an improper consideration of heat transfer and reflection. When heat is injected into a gas, the energy is primarily redistributed into translational degrees of freedom and is not used to drive emission. The average kinetic energy of the particles in the syste...
متن کاملRadiative transfer in very optically thick circumstellar disks
Aims. In this paper we present two efficient implementations of the diffusion approximation to be employed in Monte Carlo computations of radiative transfer in dusty media of massive circumstellar disks. The aim is to improve the accuracy of the computed temperature structure and to decrease the computation time. The accuracy, efficiency and applicability of the methods in various corners of pa...
