SB (Porb> = 70 yr [I.M.Coulson, MN 203, N3, 925, 1983.]). [A/H] = 0.3. There is a sguare term in the elements given in the Table: +5.34d*10**(-6)*E**2. Deviations from the parabola in the O - C, E diagram have a wave-like trend. If this wave is attributed to the light-time effect, Porb = 100 years. The observations are also satisfied by the following system of linear elements: Max = 2412874.56 + 27.0093d*E (JD2405200 - 15250) [A.V.Nielsen, AN 239, 217, 1930.]; Max = 2426004.62 + 27.0180d*E (JD2415250 - 27150); since JD2427150 - Max = 2436137.090 + 27.0205d*E [P.P.Parenago, Perem. Zvezdy 11, N4, 236, 1958.]. |
