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 (California) and Mauna Kea (Hawai'i),USA.

  • 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 (California) and Mauna Kea (Hawai'i),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.
  • HD 192699 ist ein 218,55 Lichtjahre von der Erde entfernter gelber Unterriese mit einer Rektaszension von 20h 16m 06s und einer Deklination von +04° 34' 05" . Er besitzt eine scheinbare Helligkeit von 6,44 mag. Im Jahre 2007 entdeckte John Asher Johnson einen extrasolaren Planeten, der diesen Stern umkreist. Dieser trägt den Namen HD 192699 b.
  • HD 192699 és una estrella de la constel·lació d'Aquila. És una subgegant groga de la magnitud aparent 6'45, està a la distància de 220 anys-llum. Si ens basam en la seva massa, que és 1'68 vegades la del Sol, és del tipus A de la seqüència principal. L'abril de 2007 es va anunciar que un planeta orbitava aquesta estrella, juntament amb l'anunci de HD 175541 b i HD 210702 b.
