The systemic velocities of four long-period cataclysmic variable stars
R. C. North, T. R. Marsh, U. Kolb +2
Although a large number of orbital periods of cataclysmic variable stars (CVs) have been measured, comparison of period and luminosity distributions with evolutionary theory is aff…
The mass ratio distribution of short period double degenerate stars
P. F. L. Maxted, T. R. Marsh, C. K. J. Moran
Short period double degenerates (DDs) are close white dwarf - white dwarf binary stars which are the result of the evolution of interacting binary stars. We present the first defin…
Radial velocity measurements of white dwarfs
P. F. L. Maxted, T. R. Marsh, C. K. J. Moran
We present 594 radial velocity measurements for 71 white dwarfs obtained during our search for binary white dwarfs and not reported elsewhere. We identify three excellent candidate…
The triple degenerate star WD1704+481
P. F. L. Maxted, T. R. Marsh, C. K. J. Moran +1
WD1704+481 is a visual binary in which both components are white dwarfs. We present spectra of the H-alpha line of both stars which show that one component (WD1704+481.2 = Sandulea…
A mystery solved: the mass ratio of the dwarf nova EM Cygni
R. C. North, T. R. Marsh, C. K. J. Moran +3
We have discovered that the spectrum of the well-known dwarf nova EM Cyg is contaminated by light from a K2-5V star (in addition to the K-type mass donor star). The K2-5V star cont…
Orbital periods of the binary sdB stars PG0940+068 and PG1247+554
P. F. L. Maxted, C. K. J. Moran, T. R. Marsh +1
We have used the radial velocity variations of two sdB stars previously reported to be binaries to establish their orbital periods. They are PG0940+068, (P=8.33d) and PG1247+554 (P…
