摘要
New photometric observations of the Wolf-Rayet binary HD 211853 are presented. The period search routine confirms the period of 6.6884 days for pair A. For pair B, a new corrected ephemeris (T-0 = 2443689.16, P = 3.4696 days) is determined. This ephemeris allows to present light minima of all available photometric data in the same phase. Moreover, they are in good accordance with the absorption lines radial velocity residuals of Hiltner (1945) and Massey (1981). It is shown that the third possible period of 2.34607 days found by Panov and Seggewiss (1990) is an alias from the half period of similar to 3.47 days.
