EUV Emission from RS CVn binaries C.K. Mitrou, M. Mathioudakis, J.G. Doyle and E. Antonopoulou A&A, in press We performed a study of 104 RS CVn systems in the extreme ultraviolet (EUV) using the all--sky survey data obtained by the Extreme Ultraviolet Explorer (EUVE). ... The dwarf systems exhibit a levelingoff for the faster rotators. ... For the RS CVn systems the losses in the EUV represent a smaller fraction of the coronal radiative losses, as compared to active late--type dwarfs. ...

In 2001, Westerbork observations of the disturbed galaxy named VV-29 (alias Arp-188, UGC-10214) showed that there is second smaller galaxy (named VV-29c) that appears behind the western side of the main body of the distorted galaxy. ... The galaxy was featured as the May 2, 2002 Astronomy Picture of the Day . ... When VV-29 had its 15 minutes of fame in May 2002, it appeared under the name "The Tadpole Galaxy," but based on the images above, we will always think of it as "The CHAINSAW"! ...
