STF 93 alp Umi = 1 UMi = Polaris. Cepheid variable and spectroscopic binary,
P = 30y. A close companion has been suspected. The close pair,
measured three time from 1937-1939 by R.H. Wilson using an eyepiece WRH1941b
interferometer, was not seen again until Evans et al. (2006) resolved Evs2006
it with HST. Wilson's measures agree with the combined astrometric/
spectroscopic solution by Gerasimovic (1936), although both orbit and Ger1936
measures are called into dispute by the more recent orbit of Wielan et Wln2000
al. (2000), whose solution includes mass estimates, etc.
NPOI Limb-darkened diameter 3.28 +/- 0.02 mas, NOI1999
R = 46. +/- 3. \rsun.
An earlier orbit by Wyller (1957) was rejected from Fourth Orbit Wye1957
Catalog ("amplitude below noise level") Wor1983
Component B = BD+88@@@7. See discussion of this system by Roemer. Re_1965
While Hipparcos parallax of A 7.56 +/- 0.48 from the original mission HIP1997a
and 7.54 +/- 0.011 mas from the re-reduction, the HST-FGS parallax of VlF2007
B = 6.26 +/- 0.24 mas implies that that A is high luminosity and BdH2018
pulsating in the second overtone if AB is physical, i.e., the distance
to B is the same as A.
The C component was observed by Burnham in the late 19th century, then Bu_1894
not seen again until the early 21st century by Daley and Ashcroft. Dal2006a
The extremely large magnitude makes the pair too close for most large
astrometric surveys.
The D component has also been recently recovered in 2MASS data. TMA2003
According to Jim Daley, the R-I color for C is 0.56 and for D it is
0.67. The V-I color for D is 1.08. Dal2006b
Published measures precessed to J2000 are here "X" coded. Measures CIA2024c
precessed back to date of observation to maintain consistency with
other cataloged measures.
Mean diameter of the primary is 3.143 +/- 0.027 mas. At the Gaia
distance of 136.90 +/- 0.34 pc this corresponds to 46.27 +/- 0.42 \rsun
NPOI uniform disk diameter 3.110 +/- 0.005 mas, Limb darkened diameter
3.284 +/- 0.006 mas. NOI2025
