discov_num notes refcode
LAB 1 Aa,Ab: tau Per = 18 Per. Spectrum composite; G4III+A4V. A is a
long-period spectroscopic binary, resolved by speckle interferometry. Lab1974
Speckle observations have resolved the pair and invalidate an
astrometric solution by Kamper (1969). Kam1969a
van de Kamp & Andersen orbit rejected from Fourth Orbit Catalog Kam1969a
("amplitude below noise level") Wor1983
Time of 1989 mideclipse determined as JD = 2447542.31+/-0.01d. DSH1991
Eclipse duration is 2.09d. Inclination of orbit is 88.74deg.
Time of 1989 mideclipse determined as JD = 2447542.34d. Their model REG1992
results give 16 \rsun, 2.4 \msun, Sp G8IIIa and Teff = 5160+/-150 for
the primary and 2.2 \rsun, 1.8 \msun, Sp A3/4V and Teff = 8970+/-150
for the secondary. The mass ratio is 1.1+/-0.2.
Time of 1989 mideclipse determined as JD = 2447542.302/-0.007d. Smk1990
Eclipse duration is 1.936+/-0.029d. P = 1515.869+/-0.059d.
Time of 1984 mideclipse determined as JD = 2446026.48+/-0.05d. XXX1986
Eclipse duration is 2.3-3.1d.
Zeta Aurigae-type binary.
The elements P, T, e, and longitude of periastron for the McAlister McA1981c
(1981) orbit are from the orbit by Colacevich (1941). Cla1941
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Demircan & Selam (1992). Dmr1992
The 52" distant, visual double BC may be physical.
