discov_num notes refcode
HEG 2 R Aqr. Binary system consists of a Mira-type and a white dwarf
companion, estimated P=44yr (Willson, L.A., Garnavich, P., & Mattei,
J.A. 1981 IBVS 1961, 1). Hollis et al. (1997) give preliminary orbital HJM1997
elements for the AB pair: P=44y, e=0.8, T=JD2442100.0, i=70deg,
Omega~90deg, omega = +/-90dega = 2.54e14cm for system mass 2.5 Msun,
2.69e14cm for 3.0Msun.
