WDS 15578+5916 PIN 10 : NOTES

discov_num	notes	refcode
PIN 10	Secondary is M9V, pm -0.30 +/- 0.02, 0.21 +/- 0.01 arcsec/yr, distance
	34 +/- 2pc. Given the van Leeuwen (2007) proper motion (-0.296 +/-	VlF2007
	0.001, 0.203 +/- 0.002 arcsec/yr) and distance (31 +/- 1pc) for the
	primary, the pair is likely a true CPM system. At a projected
	separation of 3800 au, the gravitational binding energy makes this one
	of the most fragile binaries known.	Thn2013
