Exoplanet research with SAFARI
A far-IR imaging spectrometer for SPICA
Javier R. Goicoechea (UCM/CSIC, Madrid, Spain)
Kate Isaak (Cardiff University, U.K.) Bruce
Swinyard (Rutherford Appleton Laboratory, U.K.)
On behalf of the SAFARI consortium

• Science questions in the field of exoplanets
  and planet formation with SAFARI
• Stellar far-IR photometric excesses (disks!).
• Protoplanetary disks from gas to snow lines.
• Primary and secondary transits in the far-IR.
• Searching for spectral signatures of transiting
  exoplanets (water vapor, HD, biomarkers).

• JAXA-led SPICA Mission mid- and far-IR
• cooled (lt5 K) space telescope (D3.5m)
• SAFARI instrument far-IR imaging-FTS
• Wavelength coverage of 33-210mm
• Field of view of 2 x 2
• Spectroscopy (R2,000) photometry (R3)

What could be observed in the case of Super-Ios
and Hyper-Ios?Danielle Briot Jean Schneider

• We study the case of a Earth, or a Super-Earth
  with a volcanic
• activity as strong as Ios.
• We call such an object a Super-Io and a Hyper-Io
  in the case of a Super-Earth.
• In case of a transit, sulphur dioxid could be
  observed in the atmosphere
• These objects are very good candidates for
  secondary transits observations, specially at 3.5
  ?m, and the hot spots corresponding to volcanoes
  could be detected in the first part and the last
  part of the secondary transit.
• - These objects could be easily observed by
  imaging in the infrared, specially in a case of a
  cool star.
