The AM Her-type of mass-transfer binary displays strong circular polarization in its optical flux, due to high harmonic cyclotron emission from the vicinity of the accretion shock. Circular polarization is the best direct evidence for magnetic white

Effective temperatures have been recalculated for the M dwarf observed by Berriman and Reid in 1987 (MNRAS, 227), using updated apparent magnitudes where appropriate. The results show that the corrections to the photometry have little effect on the d

This paper uses the variation with redshift of the near-infrared colors of the Palomar Green Bright Quasars as the basis for an analysis of the origin of their infrared light. Comparison of the data with simple models of the continuum, appropriately

Origine de la lumiere IR entre 1 et 2 μm pour un echantillon de 28 binaires cataclysmiques, pour la plupart des novae naines en repos. La lumiere IR provient de la naine rouge qui fournit de la matiere a son compagnon naine blanche et au disque d'ac

We present optical and IR observations of the dwarf nova OY Car during the May 1985 superoutburst. From them we find that the superhump has a temperature of ~8000K and an area of order half the size of the red dwarf or accretion disk. We also compare
