discov_num notes refcode
ISO 12 the Aql = 65 Aql. A is a spectroscopic binary, P = 17.12d.
The Aa,Ab pair cannot be this object.
BU 1540 AB: Incorrectly identified as H 6 27 in BDS. Error noted by MacEvoy. McE2010
MKT 10 the Aql.
Visual orbit by Hummel et al. (1995) based on astrometry from Mark III MkT1995
interferometer. Additional spectroscopic data yield component masses,
luminosities, radii, effective temperatures, and distance.
Pourbaix gives combined solution for this resolved SB2, yielding Pbx2000b
orbital parallaxes and component masses.
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Hummel et al. (1995). MkT1995
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 10.09 +/- 0.66, 9.08, and 2.88 Msun, respectively. Mlk2012
Ma,Mb = 3.564 +/- 0.049, 2.739 +/- 0.037 \msun.
Ra,Rb = 4.76 +/- 0.14, 2.34 +/- 0.07 \rsun.
Teff_a,Teff_b = 10300 +/- 200, 10230 +/- 220 K.
La,Lb = 229.8 +/- 22.5, 54.0 +/- 5.8 \lsun. distance = 76.3 +/- 0.3 pc. CIA2022e
