HD 192699 is a yellow subgiant star located approximately 220 light-years away in the constellation of Aquila. It has the apparent magnitude of 6.45. Based on its mass of 1.68 solar, it was an A-type star when it was a main-sequence. We report precision Doppler measurements of three intermediate-mass subgiants from Lick and Keck Observatories in Mount Hamilton and Mauna Kea, USA. All three stars show variability in their radial velocities consistent with planet-mass c...

HD 192699 is a yellow subgiant star located approximately 220 light-years away in the constellation of Aquila. It has the apparent magnitude of 6.45. Based on its mass of 1.68 solar, it was an A-type star when it was a main-sequence. We report precision Doppler measurements of three intermediate-mass subgiants from Lick and Keck Observatories in Mount Hamilton and Mauna Kea, USA. All three stars show variability in their radial velocities consistent with planet-mass companions in Keplerian orbits. In April 2007, a planet was announced orbiting the star, together with HD 175541 b and HD 210702 b.
