LAB 2 Aa,Ab: bet Per = 26 Per = Algol , prototype of the Algol-type binaries.
The eclipse phenomena, known since historical times (although the time
of minimum brightness was first measured by Montanari on 8 Nov 1670)
was first explained as an eclipsing binary by Goodericke as early as
1782. According to R.G. Aitken, this was verified when it was noted as A__1935f
the second spectroscopic binary based on photographic spectra
obtained by Prof. H.C. Vogel at Potsdam in November, 1889. Belopolsky
discovered a variation in the radial velocity with a period of order
1.8 years, later resolved by Labeyrie and his speckle camera in 1973; Lab1974
the magnitude difference is about 2.5.
The binary, a radio and X-ray source, is triple (and possibly
quadruple, but the variation with the 32 yr period is more probably an
apsidal rotation of the eclipsing pair).
The spectroscopic data were discussed by Hill et al. (1970, 1971). HlG1970
ADS lists several distant, faint, and probably optical companions. HlG1971
Elements P, T, e, and omega for Labeyrie et al. (1974) orbit adopted Lab1974
from the spectroscopic orbit of Hill et al. (1971).
Analysis of the spectroscopic/interferometric orbit is given by
Bonneau (1979) Bnu1979
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Hipparcos astrometric solution adopts some elements from the orbits of HIP1997d
Pan et al. (1993) and MkT1993a
Gatewood et al. (1995). Gat1995
Peterson et al. (2011) orbits of both the outer (LAB 2Aa,Ab) and Ptn2011
inner (CSI 1Aa1,Aa2) are based on VLBI measures combined with
speckle and radial velocity data. Assuming masses of the primary and
secondary of 3.70 and 0.79 Msun, respectively, they derive a mass for
the tertiary of 1.51 +/- 0.02 Msun.
