Remark:
ADS 10418 A (B 5.39m, 4.9", 107deg, 1973; B - SB2,
G5III + F2V). Slow variations, P ~6yr, Delta(m) ~0.5m;
quicker changes, P ~ 50d - 155d, Delta(m) ~ 0.3m - 1.0m.
Together with the visual companion the
star is surrounded by an enormous envelope (R ~2*10**5R$,
expansion velocity 10 km/s, mass loss 3*10**(-8)M$/yr).
