discov_num notes refcode
STT 596 iot Peg = 24 Peg. The primary is a spectroscopic binary.
Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
PTI 1 SB2. Combined solution by Boden et al. (1999), including visibilities Bod1999a
from the Palomar Testbed Interferometer, plus spectroscopy. Authors
give two very similar solutions, made using two data sets. Values were
averaged in the orbit catalog.
See also discussion of iot Peg system by Morel et al. (2000). Mrl2000
Combined spectroscopic/astrometric solution, based on high-resolution
echelle spectra plus archival PTI visibility measurements.
Derived masses 1.33249 +/- 0.00086 and 0.83050 +/-0.00055 Msun,
distance 11.534 +/- 0.019 pc. Knc2010
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.27 +/- 4.55, 2.36, and 1.20 Msun, respectively. Mlk2012
