Chromospheric variabilities of M active stars based on Guoshoujing Telescope
Published online by Cambridge University Press: 06 January 2014
Abstract
For the M active catalogue of Guoshoujing Telescope (LAMOST), 933 sources are presented in at least two exposures. We found that many M active stars show chromospheric variability in the Ca II H, Hα, Hβ, and Hγ lines on short or long timescales.
