LWR 19 V342 Peg. Based on the proper motion of A and change in relative
position, Close et al. (2010) conclude B and C are background objects. Clo2010
AD: Found in SDSS data. Position angle estimated by catalog editor
based on Aladin image.
MAR 1 The Ab, Ac, and Ad components are Jovian-mass planets in orbit around
HR 8799. Projected separations are 68, 38, and 24 au; orbital periods
(assuming pole-view circular orbits) are estimated at 460, 190, and
100 years. Masses are 5-11, 7-13, and 7-13 Mjup, respectively. Mar2008
The Aa, Ab, Ac, and Ad components all appear to be co-moving. Vig2012
CHARA Array Limb-darkened diameter 0.342 +/- 0.008 mas. CIA2012d
R = 1.44 +/- 0.06 \rsun, Teff = 7193 +/- 87K, L = 5.05 +/- 0.29 \lsun.
