DAE 9	WSP 12. WASP-12. Bergfors et al (2013) estimate spectral types G0V	Brg2013
	and K0-M0V. WASP-12b is one of the largest and hottest transiting
	planets; period 1.09d. Bergfors 6 is a point source ~3 mags fainter,
	at a separation of 1". Based on color, the companion is an M0-M1 main-
	sequence star. Relative photometry suggests Bergfors 6 is ~50% closer
	to Earth than is WASP-12, and that their consistent radial velocities
	are coincidental. If Bergfors 6 is a binary M dwarf system near
	conjunction, however, it could lie at a similar distance to WASP-12
	and the system could be gravitationally bound.	Csf2012
BEC 1	BC: Bechter et al. (2014) resolved the 1" companion to WASP 12 into 2
	~equal magnitude stars, separated by 84 mas. Both components appear to
	be physically associated with the primary. Spectral types of B and C
	components M3V, masses 0.38 +/- 0.05 and 0.37 +/- 0.05 Msun.	Bec2014
