资源简介:

CC Eri is a binary flare star, with a short orbital period of 1.56 days.Previous observations have shown it to be variable at optical, UV, radio andXray wavelengths. We propose to observe CC Eri with both the Xray instrumentsand the Optical Monitor to investigate the thermal structure of the corona, bothduring quiescent periods and during the occurrence of any flare. Timedependentspectroscopy will be used to look for variations in elemental abundances,densities and emission measures during flares, to be compared with solar flares.Flare decay profiles will be modelled to determine loop lengths and reconnectionrates. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
