discov_num notes refcode
I 1588 Slightly variable. Central star of planetary nebula.
SNA 40 Aa,Ab: This magnetic O star is resolved by PIONIER as an equal-
brightness pair with rho=20.3mas. Adopting a parallax of 2.35 +/- 0.78
mas (van Leeuwen 2007), it would correspond to a projected separation VlF2007
of 40au. While the object is flagged as SB in Simbad, a spectroscopic
study by Naze et al. (2008, 2010) reported no evidence of binarity. Naz2008
The faint companion detected at 3.3" may correspond to the 2.9" B Naz2010
companion reported by Mason et al. (1998) if the latter is a high Msn1998a
proper motion (possible foreground) object. Sna2014
