In the optical and ultraviolet regions of the electromagnetic spectrum, UX Ursae Majoris is a deeply eclipsing cataclysmic variable. However, no soft X-ray eclipse was detected in ROSAT observations. We have obtained a 38 ksec XMM-Newton observation

We present high resolution optical and UV spectra of the 46 min orbital period, helium binary, GP Com. Our data contains simultaneous photometric correction which confirms the flaring behaviour observed in previous optical and UV data. In this system

We employ high-resolution echelle spectroscopy to measure the projected rotational velocity, V r o t sin i, in the post-common-envelope binaries EG UMa, HZ 9 and RE J1629 + 780. For EG UMa we obtain consistent V r o t σin ι measurements from the Na

We present high-resolution echelle spectroscopy that confirms, via the identification of numerous chromospheric emission lines, the extremely high levels of chromospheric activity displayed by the secondary stars in post-common-envelope binaries (PCE

We have analyzed Hubble Space Telescope (HST) archival and IUE NEWSIPS archival SWP spectra of the dwarf novae CM Del and AH Her obtained when AAVSO light-curve data indicated the occurrence of dwarf nova quiescence. We have computed synthetic, high-

We present spectra in the range 8000–8665 A of the close, detached M-dwarf–white-dwarf binaries EG UMa and PG 1026+002. The Na i absorption doublet (8183, 8195 A) is detected along with a number of other absorption lines including intrinsically n

ABSTRA C T An analysis of the UV oscillations in WZ Sge is presented, in which we obtain the oscillation amplitude spectra. We find a strong 27.9-s oscillation in our Hubble Space Telescope (HST) UV and zeroth-order light curves as well as weaker osc

We present optical spectroscopy of the post-common envelope binary HW Vir covering λ =3704-8667 A. We use the low-resolution blue spectra to determine the atmospheric parameters of the sdB primary star and the medium resolution Hα observations to m

We present spectroscopy of three post-common envelope binaries, with complete orbital coverage of RE 1016-053. For the latter target we have measured the radial velocities and line strengths and mapped the line emissivity on the surface of the second
