(k - b)2 = 021; Delta(S) = 0. P var? Max = 2437192.3131 + 0.0671786d*E (JD2437180 - 460) [J.Churms, D.S.Evans, Obs 81, 25, 1961.]; Max = 2439320.2162 + 0.0671575d*E (JD2439320 - 340) [K.C.Leung, AJ 73, 500, 1968.]; since JD2440440 - see Table. Further period increase is possible [L.A.Balona, W.L.Martin, MN 184, 11, 1978.]. According to [J.R.Percy, MN 181, 647, 1977.] there are two simultaneous oscillations with the periods P1 and P2: P1 = 0.0654d, P2 = 0.0513d. P2/P1 = 0.784; A2(U) = 0.25 A1(U). |
