The long - period RS CVn binary IM Pegasi


New high-resolution, high signal-to-noise ratio spectroscopic observations and UBV photometry carried out in 1996–1999 were analysed with the surface imaging technique. A total of 8 images of IM Peg was obtained for the first time. A huge high-latitude active region was found to dominate the stellar surface and decreased in area during the period of the… (More)
