BLA 11 Aa,Ab: eta Peg = 44 Peg = Matar. Spectroscopic binary resolved by
speckle interferometry. Spectrum of Aa,Ab is composite; G2II-III+F0IV.
Hence a quadruple system.
The elements P, T, e in the astrometric solution by van de Kamp &
Damkoehler (1957) have been taken from the spectroscopic orbit by Kam1957
Crawford. The astrometric amplitude is marginal and not certainly real
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Crawford (1901). Crw1901
Aa,Ab: Malkov et al. (2012) derive dynamical and spectroscopic masses
5.17 +/- 0.72 and 3.35 Msun, respectively. Mlk2012
Aa,Ab: Ren & Fu (2013) calculated an astrometric orbit, combining Ren2013
Hipparcos Intermediate Astrometric Data with spectroscopic elements by
Massarotti et al. (2008). Msr2008
NPOI Limb-darkened diameter 3.471 +/- 0.027 mas, Sp = G2III, NOI2018
R = 24.51 +/- 1.16 \rsun, Teff = 4970 +/- 65 K,
L = 330.8 +/- 35.0 \lsun, M = 3.51 +/- 0.13 \msun,
Age = 0.27 +/- 0.03 Gyr.
BU 1144 The pair BC (mags. 10.1-10.1, 0.3") is 91" distant and probably
physical; B is BD+29@4740.
Aka H 6 21 = S 816.
