| 英文摘要 | We present a spectroscopic catalog of 93 619 Mdwarfs from the first data release of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) general survey. During sample selection, M giant contamination was eliminated using 2MASS photometry and CaH/TiO molecular indices. For each spectrum, the spectral subtype and values are provided including radial velocity, H alpha equivalent width, a series of prominent molecular band indices, and the metal-sensitive parameter zeta, as well as distances and the space motions for high S/N objects. In addition, H alpha emission lines are measured to examine the magnetic activity properties of Mdwarfs and 7179 active ones are found. In particular, a subsample with significant variation in magnetic activity is revealed through observations from different epochs. Finally, statistical analysis for this sample is performed, including the metallicity classification, the distribution of molecular band indices and their errors. |
