[131.07] Low Mass Template Spectra from SDSS

J.J. Bochanski, A.A. West, S.L. Hawley, K.R. Covey (U. of Washington)

We present mean template spectra of low mass dwarfs as observed by the Sloan Digital Sky Survey (SDSS). These extremely high signal-to-noise templates result from co-adding observations of stars with similar spectral types. We make use of ~ 12,000 unique low mass stellar spectra to construct a set of templates spanning the spectral types, M0-L2. We measure the spectral and photometric properties of these mean templates, and report on H-alpha emission (due to chromospheric activity) and molecular band strengths. These pristine spectra are suitable for use as radial velocity cross-correlation templates as well as illuminating many of the mean properties of low mass stars.

We gratefully acknowledge the support of NSF grant AST02-05875 and NASA ADP grant NAG5-13111.
