We use multi-band photometry to refine estimates for the planetary radius and orbital inclination of the transiting planet system HD 209458. We gathered 1066 spectra over four distinct transits with...
A stellar companion in the HD 189733 system with a known transiting extrasolar planet (2006)
Bakos, Gaspar A., Pal, Andras, Latham, David W., Noyes, Robert W., Stefanik, Robert P.
We show that the very close-by (19 pc) K0 star HD 189733, already found to be orbited by a transiting giant planet, is the primary of a double-star system, with the secondary being a mid-M dwarf with...
