SWB 1 Primary is the eclipsing binary KIC 4862625 (P=20d), which hosts a
transiting circumbinary planet (P = 138.317 +0.040/-0.027 d). Planet
mass < 169 Mearth (0.531 Mjup), planetary system age ~2 Gyr. The B
component is a close visual pair, separation <0.4"; radial velocities
confirm AB as a bound pair. Component parameters, based on model
fitting, are as follows:
Aa = F dwarf, radius 1.734 +/- 0.044 Rsun, mass 1.528 +/- 0.087 Msun
Ab = M dwarf, radius 0.378 +/- 0.023 Rsun, mass 0.408 +/- 0.024 Msun
Ba = G2 dwarf, mass ~0.99 Msun
Bb = M2 dwarf, mass ~0.51 Msun Swb2013
