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 |

("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. |
