STF 748 A: the 1 Ori A = 41 Ori A = V1016 Ori
B: the 1 Ori B = 41 Ori B = BM Ori
C: the 1 Ori C = 41 Ori C
D: the 1 Ori D = 41 Ori D
Trapezium. the Ori A, B, and C were first noted as a triple by G__1617
Galileo on 4 February 1617. It was independently found as a triple in
by Christian Huygens, who is often given credit for recognizing this
multiple system. the Ori D was found by Abbe Jean Picard, as A__1935f
documented by a manuscript drawing of 20 March 1673. The D component
was independently found by Huygens in 1684.
A and B are both Algol-type systems, C is an RW Aur-type system.
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
the A component is from Morrell & Levato (1991). Msn1998a
AB: H 3 1. MEv2010
AC: C component = D component of 05354-0525 STFA 17.
WGT 1 Ca,Cb: The longer-period Kraus et al. (2007) solution gives a dynamic
parallax 2.304 +/- 0.066 mas, the shorter-period solution gives 2.585
+/- 0.074 mas. Mass sums are 47.8 +/- 4.2 and 44.8 +/- 3.9 Msun,
respectively. Based on evolutionary models, spectral types for Ca and
Cb are O5.5 and O9.5, masses are 34.0 and 15.5 Msun. Kss2007
The Kraus et al. (2009) solution is based on VLTI data from 2007-2008,
plus speckle (1997-2008) and radial valocity data. They derive a
dynamic distance of 410 +/- 20pc and a system mass of 44 +/- 7 Msun. Kss2009
Ca,Cb: From their combined astrometric/spectroscopic solution, Balega
et al. (2015) derive the following properties for the system:
total mass (Msun): 45.5 +/- 10.0
mass ratio: 0.36 0.05
distance (pc): 414 7
flux ratio: 0.30 0.05
Resulting properties for the two components are:
mass (Msun): 33.5 +/- 5.2 12.0 +/- 3.0
log L: 5.21 0.01 4.70 0.15
Spectral types: O6Vp B0V
Teff 39000 1000 30000 1000
radii (Rsun): 8.91 0.50 8.24 0.50 Bag2015
STF 748 CH: Additional notes may be found in Burnham (1894). Bu_1894
KSS 1 D component of ADS 4186 = the 1 Ori D
PTR 1 Ab is a 4 solar mass PMS F star. Gvt2018
GVT 1 Be is a 4-6 solar mass B star. Gvt2018
GVT 1 Dc is a 5-7 solar mass B star. Gvt2018
DAE 130 Oa,Ob: The elongated shape of JW 519's primary suggests the primary to
be binary itself. The photometry for JW 519, however, is based on the
assumption of a single central object since separate components cannot
be identified. Dae2012

REP 110 Xa,Xb: AF Ori
