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 |
