A New Stellar Companion to GJ 1292.

CLARK C.A.

Abstract (from CDS):

I present the discovery of a new stellar companion to GJ 1292 detected with the NN-EXPLORE Exoplanet and Stellar Speckle Imager at the 3.5 m WIYN Telescope. The companion was detected at an angular separation of 0.″1244, a position angle of 44°, and a delta magnitude of 0.97 at 832 nm. I also estimate a projected separation of 2.09 au, a mass ratio of 0.69, and component spectral types of M2.5 and M3.
