WDS 19539+4425 GIC 159 AB : NOTES
 
 
discov_num notes refcode
MCY 3 Aa,Ab: Discovery designation is per Todd Henry 03/02/98.
Aa,Ab: LSPM J1953+4424 = GJ 1245. Law et al (2008) derive a distance Law2008
of 4.54 +0.02/-0.02 pc and a projected separation of
4.6 +0.05/-0.05 au. Estimated spectral types are M5 and M8.5.
GIC 159 AB = the red dwarf binary G208-044/G208-045 = GJ 1245AB = GIC 160.
The A component is the variable star V1581 Cyg.
AB: NLTT 48414/48415 Chm2004
Both the A and B components are active M5 stars, and exhibit an
average of 3.0 and 2.6 flares per day, respectively, based on Kepler
short-cadence observations. Lur2015
