Images for Gemini Observatory Press Release on Planetary First Family
A K-band (2.2microns) AO image of the HR 8799 planetary system made using Gemini/Altair/NIRI and acquired on September 5, 2008 (North is up and East is left). The three planets are designated with red circles. The stellar flux has been subtracted using ADI (see text for details) and the central saturated region is masked out. Multiepoch observations have shown counterclockwise Keplerian orbital motion for all three planets.

Image shows two of the three confirmed planets indicated as "b"and "c" on the image above. "b" is the ~7 Jupiter-mass planet orbiting atabout 70 AU, "c" is the ~10 Jupiter-mass planet orbiting the star atabout 40 AU. Due to the brightness of the central star, it has beenblocked and appears blank in this image to increase visibility of theplanets.
