Remarks

20 Nov 2014: The binary star orbit has an inclination 81 Deg. (Lee et al; 2014)
20 Dec 2011: NY Vir is a rapidly pulsating subdwarf B-type ecplipsing binary with:
- for component 1: M1 = 0.46 MSun, T1= 33000 K
- for component 2: M2 = 0.14 MSun, T2 = 3000 K
and a binary period = 0.101 d (Qian et al. 2011). The present table gives the total mass M1 + M2 and T = T1.
