Circumstellar features in hot DA white dwarfs
We present a phenomenological study of highly ionised, non-photospheric absorption features in high spectral resolution vacuum ultraviolet spectra of 23 hot DA white dwarfs. Prior to this study, four of the survey objects (Feige 24, REJ 0457-281, G191B2B and REJ 1614-085) were known to possess these features. We find four new objects with multiple components in one or more of the principal reso...
متن کاملStellar Surface Convection, Line Asymmetries, and Wavelength Shifts 1. Solar Line Asymmetries and Shifts
Wavelength positions of photospheric absorption lines may be aaected by surface convection (stellar granulation). Asymmetries and wavelength shifts originate from correlated velocity and brightness patterns: rising (blueshifted) elements are hot (bright), and convective blueshifts result from a larger contribution of such blueshifted photons than of redshifted ones from the sinking and cooler (...
متن کاملA source of high–velocity white dwarfs
We investigate whether the recently–observed population of high–velocity white dwarfs can be derived from a population of binaries residing initially within the thin disk of the Galaxy. In particular we consider binaries where the primary is sufficiently massive to explode as a type II supernova. A large fraction of such binaries are broken up when the primary then explodes as a supernova owing...
متن کاملStellar Masers, Circumstellar Envelopes, and Supernova Remnants
This paper reviews recent advances in the study or circumstellar masers and masers found toward supernova remnants. The review is organized by science focus area, including the astrophysics of extended stellar atmospheres, stellar mass-loss processes and outflows, late-type evolved stellar evolution, stellar maser excitation and chemistry, and the use of stellar masers as independent distance e...
متن کاملType Ia Supernovae and High Velocity White Dwarfs
I examine the hypothesis that many of the high velocity white dwarfs observed by Oppenheimer et al. (2001) are the remnants of donor stars from binaries that produced type Ia supernovae via the ‘single degenerate’ channel. If this channel is a significant contributor to the Galactic SN Ia supernova rate, then the local density of such remnants with V⊥ > 100 km.s −1 could be as high as 2×10pc, c...
