A Unified Analysis of Time Variability in Chandra Grating Observations of Low-Mass Stars
Abstract
We are carrying out a unified study of archival Chandra grating observations of active low-mass coronal stars and present preliminary results here. We include ACIS-S/HETG, ACIS-S/LETG, and HRC-S/LETG observations. Gratings data are optimal for timing analysis since they are free from pile-up and allow for joint spectro-temporal analysis. We discuss techniques for timing analysis of gratings data and explore the distribution of stellar flare energies and the time variability of individual lines fluxes. This work is supported by CXC NASA contract NAS8-39073 and Chandra grant AR0-11001X.
