A Catalog of Cool Dwarf Targets for the Transiting Exoplanet Survey Satellite
Philip S. Muirhead, Courtney Dressing, Andrew W. Mann +5
We present a catalog of cool dwarf targets (, ) and their stellar properties for the upcoming Transiting Exoplanet Survey Satellite (TESS), fo…
The M-giant star candidates identified in the LAMOST data release 1
Jing Zhong, Sebastien Lepine, Jing Li +6
We perform a discrimination procedure with the spectral index diagram of TiO5 and CaH2+CaH3 to separate M giants from M dwarfs. Using the M giant spectra identified from the LAMOST…
Twenty-three new ultra-cool subdwarfs from the Sloan Digital Sky Survey
Sebastien Lepine, Ralf-Dieter Scholz
A search of the Sloan Digital Sky Survey spectroscopic database has turned up 23 new ultra-cool subdwarfs, low-mass metal-poor stars of spectral subtype M 7.0 or later. Spectra fro…
Revised metallicity classes for low-mass stars: dwarfs (dM), subdwarfs (sdM), extreme subdwarfs (esdM), and ultra subdwarfs (usdM)
Sebastien Lepine, R. Michael Rich, Michael M. Shara
The current classification system of M stars on the main sequence distinguishes three metallicity classes (dwarfs - dM, subdwarfs - sdM, and extreme subdwarfs - esdM). The spectros…
Discovery of an ultra-cool subdwarf: LSR1425+7102, first star with spectral type sdM8.0
Sebastien Lepine, Michael M. Shara, R. Michael Rich
We report the discovery of the coolest subdwarf reported to date. The star LSR1425+7102 was discovered in our survey for faint high proper motion stars in the northern sky. Follow-…
