Detection of the secondary star in three AM Her systems
Description
This paper reports low-resolution spectrophotometry in the region 6000-9500 A, of three AM Her-type systems, with the Isaac Newton Telescope, and UKIRT photometry of two of them. PG1550+191 (MR Ser) was found to be in a low state; the others, CW1103+254 (ST LMi) and E2003+225(QQ Vul), were not. In all three cases spectral features characteristic of late-M stars were detected. We also report on the infrared photometry of two of the systems, enabling us to refine the distance estimates. (author)
