suggest that the visible companion is not the star itself, but the
accretion disc around it (material captured from Mira's stellar wind).

will certainly change little in the future; only the period is still
slightly uncertain. The Hipparcos parallax is 0".02012 +/- 0.00150.

expected values for a system of type G0. Compared to the orbit

eclipse phenomena, known since historical times (although the time of
minimum brightness was first measured by Montanari on 8 November 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

Pan et al. (2004) orbit is based on Mark III and PTI measures. A PTI2004
distance to the Pleiades of 135 +/- 2 pc is determined. Masses for the
components are calculated as 4.90 +/- 0.28 and 3.65 +/- 0.08 Msun.
Zwahlen et al. (2004) orbit is based on published Mark III and PTI Zwa2004
measures, plus additional Mark III and NPOI astrometric data and
ELODIE echelle spectra. This combined spectroscopic/interferometric
solution yields masses of 4.74 +/- 0.25 and 3.42 +/- 0.25 Msun; the
distance 132 +/- 4 pc found agrees with "traditional" Pleiades
distances obtained through MS fitting techniques.

STF 485 The classification is from Chocol (1980 Bull. Astron. Inst. Czech. 31,
CHR 209 321). The discovery of a speckle companion (CHR 209 Ea) with a period
WSI 20 of some 60 y confirms the third body model advocated by Mayer et al.
HZG 2 (1994 A&A 288, L13) based on the appearance of the spectrum and
HLM 3 variations in the time of light curve minimum (they suggest a third
body period of 50.7 y). Another light curve solution is given by
Harries et al. (1998 MNRAS 295, 386). The B component (HD 25639) was
also observed and appeared to be single. Classification of the B
component is from the WDS. Msn1998a
E is a Beta Lyrae-type system, SZ Cam, P = 2.7d.
This complex multiple system has had numerous identification errors
due to various difficulties. The diagram of Lewis in his catalog of L__1906b
the Struve pairs, which seemed a good first step, was hampered by the
quadrant error of the pair he designated Ca. This quadrant error was
repeated in the ADS, IDS, and in earlier editions of the WDS. In the
ADS (where this pair is listed as #2984, but note that #2989 is part
of this system, too) the errors multiplied. The pair Holmes AF (WDS
designation HLM 3AF) is apparently the same as STF 485Ac. Inspection
of scanned images of this region of the sky have allowed the
Hertzsprung pairs (HZG 2) whose components are given within
quotation marks in the ADS to be identified. Of the HZG pairs, the
"CD" pairing is the same as STF 484AC and the "CE" pairing is the
same as STF 484AB. The ADS note to the "AJ" pairing of HZG 2 is a
typographical error. The correct position angle is 77 degrees, which
corresponds to the AD (now AO) pair. Below outlines the changes from
the WDS 2001.0 to the current version.

This system, first announced in Mason et al. but considered of Msn1993a
uncertain veracity, has been included. While its status is not
definitive, subsequent confirmation or suspected duplicity (by another
technique) makes the discovery measurement somewhat more probable.
1991.8995: This is a particularly unexpected result, given the four
previous epochs at which our observations have shown no indications of
duplicity. All four of the earlier observations were reanalyzed using
the same procedures employed here, but no additional supporting
evidence of duplicity was found. If this additional component is
confirmed, vB 41 will be the second K0 giant binary that has been
resolved in the Hyades (HR 1411 being the other). The common proper
motion companion at a separation of 195".5 is far outside our window

those for HR 1331 (= McA 14) for the same epoch. These two stars were
observed in immediate sequence but with different microscope
objectives, and the final reductions calculated two results from the

05353-0523 STF 748 Theta (1) Ori or the Trapezium. Theta Ori A, B, and C were first noted
as a triple by Galileo on 4 February 1617. It was independently found
as a triple in 1656 by Christian Huygens, who is often given credit
for recognizing this multiple system. Theta Orionis D was found by A__1935f
Abbe Jean Picard, as documented by a manuscript drawing of 20 March
1673. The D component was independently found by Huygens in 1684. A is
an Algol-type system, V1016 Ori. B is an Algol-type system, BM Ori. C
is a RW Aur-type system, V361 Ori. Common proper motion with the
multiple system STF 16.
Stahl et al. (1996 A&A 312, 539) find that the H-alpha profiles of the
C component vary with a 15.4-day cycle which they suggest is related
to the star's rotational period; photospheric line radial velocity
variations are small. All 4 of the Orion Trapezium stars were observed
with the speckle camera (A = HD 37020; B = HD 37021; C = HD 37022;
D = HD 37023) and all appeared to be single. Classifications of the
B and D components are from the WDS. The spectral classification for Lev1991b

According to R.G. Aitken, this is the third binary recognized by A__1935f
spectroscopic methods. It was identified as such by Miss Maury at the
Harvard College Observatory in early 1890.
KOE 1 Aa: Visual orbit by Hummel et al. (1995) is based on astrometry from MkT1995
Mark III interferometer. Additional spectroscopic data yield component
masses, luminosities, radii, effective temperatures, and distance.
Pourbaix gives combined solution for this resolved SB2, yielding
orbital parallaxes and component masses. Pbx2000

HJ 3823 AB-C triple solution by Soderhjelm (1992), who notes the Hipparcos Sod1999
data are unuseable. Speckle observations needed to strengthen orbit.
TOK 9 CE: As suggested by Tokovinin et al. and after consultation with the Tok2005
author, the measure of Prieto was moved from AB to CE, as AB was Pri1997a
unresolved at the time of the observation. This measure of CE predates
the discovery by eight years.
Star D is optical.
06004-3102 HJ 3823 AC. 1997.0952: In this multiple system, our observation failed to
detect the closer pair HU 1399 AB, where the secondary has magnitude
9.2 and approximate separation 0".5. Hor1997
Tokovinin (2005) notes that a 1996 measure of the AB pair by Prieto Tok2005
(1997) may actually have been of CE, as AB was unresolvable at this Pri1997a
epoch (250deg, 0".09).

06024+0939 A 2715 Mu Ori. Alden (1942) orbit is visual. P, T, e in Osvald's (1964) Ald1942
astrometric orbit are taken from a revised visual orbit by Alden Osv1964
(cf Osvald's paper); the revised a = 0.254". The different types of
orbits cause the longitude of the node to be in opposite quadrants.
Star A is an Alpha CVn variable and SB1, P = 4.45 d; star B is SB2,
P = 4.78 d (F. Fekel 1980). Fek1980b

06036+0419 STF 837 Identical with STF 833. BAL2649.
06041+2316 KUI 23 1 Gem. Primary 9.6d SB1 (#377 in Batten et al., 1989), secondary spec Bte1989
type K1III (Strassmeier & Fekel 1990), and reported to be an Fek1990
occultation binary. Mass sum close to expected.
Evidently both visual components are giants with one, probably the
later type component, double once more.
