discov_num	notes	refcode
JNN 26	Since the two epochs of observation were acquired over a baseline of
	only a few months, there is not yet sufficient motion to confirm
	common proper motion of the companion that was detected with AstraLux.
	However, the separation between components is rather small (~0.86"),
	and the fact that the companion is clearly detected in z' but too
	faint in i' implies that it must be very red, as expected for a real
	companion. Hence, we count it as a binary system for statistical
	purposes.	Jnn2012
	Primary is an active M4.0Ve star, age 60-300 Myr. Bowler et al (2015)
	confirm B is physically bound and detect slight orbital motion. The
	projected separation is 19.8 +/- 0.9 au. Spectral type of B is
	L0 +/- 1, mass 35 +/- 8 Mjup.	Bwl2015
