Exoplanet Content in the Keck Observatory Archive

Following on from last week’s post about the Second Kepler Science Conference, the Keck Observatory Archive (KOA) is a growing resource for exoplanet science. The poster shown at the end of this post was presented at the Kepler Conference describes this. KOA, a collaboration between NExScI and WMKO, has played an important role in the follow-up of Kepler-discovered objects, including exoplanets, variable stars, and binary systems. The figure below shows the public observations in the Kepler field:

keplfIndeed, over half of the stars with confirmed planets have public data accessible KOA, and researchers are beginning to mine this content. Recent exoplanet related science papers citing KOA include:

  • Currie et al., 2013, “A Deep Keck/NIRC2 Search for Thermal Emission from Planetary Companions Orbiting Fomalhaut,” ApJL, 777, 6.
  • Fossati et al., 2013, “Absorbing gas around the WASP-12 planetary system,” ApJL, 766, 20.
  • Nielson et al., 2013, “The Gemini NICI Planet-Finding Campaign: The Frequency of Giant Planets around Young B and A Stars,” ApJ, 776, 4.
  • Teske et al., 2013, “Carbon and Oxygen Abundances in Cool Metal-rich Exoplanet Hosts: A Case Study of the C/O Ratio of 55 Cancri,” ApJ accepted.

The exoplanet content will grow considerably in the next few years. Observations from all the active instruments – seven in all – will be archived by the end of December 2013, and data from all instruments will begin to be made public by the end of 2014. The data archived include all previously acquired data and new observations, with observers having exclusive access to these new data for at least 18 months after the date of observations.
