Discovery of an M8.5 Dwarf With Proper Motion mu=2.38 arcsec/yr
Sebastien Lepine, R. Michael Rich, James D. Neill +2
We report the discovery of LSR1826+3014, a very faint (V=19.36) star with a very large proper motion (mu=2.38 arcsec/yr). A low resolution red spectrum reveals that LSR1826+3014 is…
Spectroscopy of New High Proper Motion Stars in the Northern Sky. I. New Nearby Stars, New High Velocity Stars, and an Enhanced Classification Scheme for M Dwarfs
Sebastien Lepine, R. Michael Rich, Michael M. Shara
We define an enhanced spectral classification scheme for M dwarf stars, and use it to derive spectral classification of 104 northern stars with proper motions larger than 0.5"/yr w…
New High Proper Motion Stars from the Digitized Sky Survey. I. Northern Stars with proper motion between 0.5 and 2.0 arcsec/yr at Low Galactic Latitudes
Sebastien Lepine, Michael M. Shara, R. Michael Rich
We have conducted a systematic search for high proper motion stars in the Digitized Sky Survey, in the area of the sky north of -2.8 degrees in declination and within 25 degrees of…
New distant companions to known nearby stars: I. GJ 4047B, GJ 718B, GJ 747.2C, GJ 4100B, and GJ 4153B
Sebastien Lepine, Michael M. Shara, R. Michael Rich
In an ongoing survey for high proper motion stars at low galactic latitudes, we have identified 5 previously uncatalogued common proper motion companions to stars listed in the Pre…
