Resolved Spectroscopy of M Dwarf/L Dwarf Binaries. IV. Discovery of an M9 + L6 BInary Separated by Over 100 AU
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/27
We report the discovery of a faint L6 \pm 1 companion to the previously known M9 dwarf, 2MASS J01303563-4445411, based on our near-infrared imaging and spectroscopic observations with the 3m Infrared ...
Using Absorptive Linear Polarization Spectroscopy to Understand Imbedded Stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
Sensitive measurements of the linearly polarized spectra of stars can be used to deduce geometric properties of their otherwise unresolved circumstellar environments. This paper describes some of the ...
