The Solar Neighborhood XXXV: Distances to 1404 M Dwarf Systems Within 25 pc in the Southern Sky
Autor: Altonio D. Hosey, Charlie T. Finch, Mark R. Boyd, Adric R. Riedel, Todd J. Henry, Wei-Chun Jao, Kenneth J. Slatten, Nigel Hambly, Sergio B. Dieterich, John P. Subasavage, Jennifer L. Bartlett, John C. Lurie, Philip A. Ianna, Jennifer G. Winters
We present trigonometric, photometric, and photographic distances to 1748 southern ($\delta \leq$0$^\circ$) M dwarf systems with $\mu \ge$ 0\farcs18 yr$^{-1}$, of which 1404 are believed to lie within 25 parsecs of the Sun. The stars have 6.67 $\leq$

The Solar Neighborhood XXXII. The Hydrogen Burning Limit
Autor: Wei-Chun Jao, Adric R. Riedel, Sergio B. Dieterich, Jennifer G. Winters, John P. Subasavage, Altonio D. Hosey, Todd J. Henry
We construct a Hertzsprung-Russell diagram for the stellar/substellar boundary based on a sample of 63 objects ranging in spectral type from M6V to L4. We report newly observed VRI photometry for all 63 objects and new trigonometric parallaxes for 37

Publikováno v: The Astronomical Journal. 150:6
We present an analysis of long-term photometric variability for nearby red dwarf stars at optical wavelengths. The sample consists of 264 M dwarfs south of decl. = +30 with = 3.96?9.16 and MV 10?20, corresponding to spectral types M2V?M8V, most of wh
