discov_num notes refcode
STF3135 Rabe measures principal stars STF 761 and STF 762. Rab1923
1914, 324@, 209.79". This new WDS entry created 02/18/98.
Spectral types of primary and secondary assigned by ten Brummelaar et TtB2000
al., based on adaptive optics observations.
BU 1032 sig Ori = 48 Ori. A is the variable V1030 Ori. This is the brightest
pair in a trapezium system with at least five components, including
components C (mag. 8.79, 11", A2V), D (mag. 6.62, 13", B2V), and the
helium-rich star E, BD-02@1327. A has also been reported to be a short
period SB2.
Heintz (1974) gives formulae for the motions AB,C and AB,D. Hei1974b
The suspected small RV variation of AB was not confirmed in David
Dunlap Obs. spectra.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
The AB pair has decreased in position angle from 171 deg to 125 deg
between 1975 and 1994. Fullerton (1990) describes three spectral Ful1990
components in the He I 5876 A profile which suggests that one of the
stars is a double-lined spectroscopic binary (see Bolton, 1974 ApJ
192, L7). Classifications of the B, C, and D components are from Hof1991
Hoffleit & Warren (1991), while the classification for the E Lev1991b
component is from Morrell & Levato (1991). Msn1998a
AB: Additional notes may be found in Worley (1956). Wor1956b
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 27.34 +/- 40.70, 25.32, 21.87 Msun, respectively. Mlk2012
sig Ori Aa,Ab: Simon-Diaz et al. (2015) derive a new spectroscopic orbit for
the primary (sig Ori Aa,Ab) as well as astrometry and photometry for
the AB pair. New values for mass, log g, age, Teff, etc are derived
for Aa, Ab, and B. SiD2015
NOI 6 Aa,Ab: Schaefer et al. (2016) resolved the primary of sig Ori A and
derive a new combined solution, as well as a new orbit of the AB pair.
Derived masses for Aa, Ab, and B are 16.99 +/- 0.20, 12.81 +/- 0.18,
and 11.54 +/- 1.15 Msun, respectively. They also derive a parallax of
2.5806 +/- 0.0088 mas, corresponding to distance 387.51 +/- 0.12 pc. NOI2016b
Spectral type of Aa 09.5V, Ab B0.5V Opl2023
STF 762 AB,C: H 2 11. MEv2010
Sigma Ori E (V1030 Ori) has a strong magnetic field and a magnetosphere IAU2014a
with two clouds of plasma constrained by magnetic and centrifugal
forces which co-rotate with the 1.19d period of the star which results
in eclipse features.
Note that the C component was first resolved by Dawes while D and E Da_1835
were first resolved by Mayer. However, the discovery designation is MyC1784
maintained due to the long standing historical designations.
STF3135 AB,F: F component = primary of 05386-0233 STF 761.
RAS 22 Ea,Eb: Helium star V1030 Ori, type B2; spectral type of Eb estimated
as late-A. Ras2014
CAB 26 Ha,Hb: [W96] 4771-899 = Mayrit 528005
