The application of Monte Carlo methods to the synthesis of spectral line profiles arising from accretion disc winds

Christian Knigge, J. A. Woods, J. E. Drew

A Monte Carlo line profile synthesis method is presented which allows the radiative transfer of resonantly scattered lines through a stellar wind to be solved exactly. The resulting code is designed to be used primarily in the context of non-spherical wind models, …

The donor star of the long-period dwarf nova DX Andromedae

J. E. Drew, D. H. P. Jones, J. A. Woods

Spectroscopic observations with the INT show that DX And has (i) a binary period of 0.44167 d (10.6 h), (ii) a secondary radial velocity amplitude of 107 km s–1and (iii)a projected rotational velocity of 79 km s–1. Photometric observations with the JKT …

Prominence activity in G dwarfs of the Persei cluster

Andrew Collier Cameron, J. A. Woods

We have found evidence for prominence-like circumstellar material in four rapidly rotating G–K dwarfs of the α Persei cluster, He 373, 520, 622 and 699. Our time-series Hα spectra of these stars show transient absorption features similar to those seen in the …

Time dependence of the UV resonance lines in the cataclysmic variables YZ Cnc, IR Gem and V3885 Sgr

J. A. Woods, F. Verbunt, Andrew Collier Cameron, J. E. Drew et autres

We have observed orbital variations in the ultraviolet resonance lines of YZ Cnc, IR Gem and V3885 Sgr. Optical spectroscopic observations of YZ Cnc show that the maximum absorption in the ultraviolet lines occurs |$\sim 0.7-0.8$| orbits after the transition from red …

Ultraviolet observations of the long-period dwarf nova DX And in outburst

J. E. Drew, M. G. Hoare, J. A. Woods

Ultraviolet observations of the little-studied dwarf nova, DX And, are presented. The observations were made with the International Ultraviolet Explorer satellite (IUE) during the late stages of a rise to outburst maximum in 1989 November. The spectra indicate a low orbital inclination …

An attempt to determine stellar Lyman-alpha emission-line fluxes for F stars with different metal abundances

Erika Böhm‐Vitense, J. A. Woods

We have studied stellar Lyα fluxes for F stars of different metal abundances which are presumably older the more metal deficient they are. We describe the correction procedure for the geocoronal emission and our estimate of the correction for interstellar absorption. We …
