discov_num	notes	refcode
LAS 8	Lasgoity (2014) determines that the two components of the pair in the
	region of the Coma Berenice star cluster share common proper motion.
	He derives spectral types of K4V and M0V for the two components, and
	estimates distance, mass, and radius for both stars.	Las2014a
