Multiple system (Eclipsing pair = Algol AB; Algol C 4.7m, Am, a = 0".10, Porb = 1.862a); Algol AB = ADS 2362 A (B 12.7m, 57".5, 156deg, 1920). P var. P = 2.8673442d (1784 - 1835); P = 2.8673012d (1835 - 1854); P = 2.8672775d (1854 - 1901); P = 2.8672967d (1901 - 1913); P = 2.8672506d (1913 - 1915) [T.Herczeg, Non-periodic Phenomena in Variable Stars, Budapest, 1969, P.465-470.]; Min I = 2424477.806 + 2.86730236d*E (JD2420500 - 25000); Min = 2425917.203 + 2.86732697d*E (JD2425000 - 277000); Min I = 2433194.454 + 2.86731667d*E (JD2427700 - 33600); Min I = 2433928.4944 + 2.86732442d*E (JD2433600 - 37000); Min I = 2437598.6766 + 2.86733732d*E (JD2437000 - 42200); since JD2442200 - see Table. Porb (Algol C) = 1.862a may be traced in the deviations; a period of 32a may also be real. Depth of Min I var. Variable polarization, changes in hydrogen line profiles, sometimes emissions in the spectrum. Radio source with frequent burst of different amplitude, faint X-ray source. |
