GT Observations of Active Cool Stars: Chi1 Ori

GTchi1 Ori is a solar analog with an age of only about 300 Myrs. Its consequentactivity is intermediate between zeroage mainsequence stars and the Sun. This target is part of a study on the Sun in Time. in which we investigate thedecline of coronal activity of a solar analog with time. Important aspectsconcern the emission measure distribution, the abundance pattern that might beactivity dependent, and flare variability studies with respect to temperatures,abundances, densities, and mass motions. The pn and one MOS will be used inTIMING mode, the pn with the medium filter to optimize the detection of softphotons, and the MOS with the thick filter. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
