- W1559158670 abstract "An Exosat observation of one orbital cycle of the eclipsing 3.2-d RS CVn system TY Pyx is reported. This system contains two almost identical GV stars, which is unusual because most RS CVns contain F or G main-sequence star and a K subgiant. The X-ray light curves of the primary and secondary eclipses are different above and below 1 keV. At lower energies a sharp eclipse is seen, but at higher energies it is absent. This confirms earlier observations that the 1.5-4.0 x 10 to the 7th K emission from the RS CVn systems is not eclipsed and comes from an extended region, whereas the 7 x 10 to the 6th K emission comes from more compact solarlike active regions. Modeling the X-ray eclipse detected at low energies requires two emission regions, one on each star, covering less than 20 percent of the stellar surface. To avoid a strong orbital modulation caused by both regions being either simultaneously visible, or not visible, they must be located 180 deg apart in longitude. The derived longitudes are 0 and 180 deg; i.e., they point at each other on the inward faces of the two stars." @default.
