Exoclimes related papers, June 2012

  • Application of new data analysis techniques to unveil an additional two super Earths and a possible outer gas giant in RV data for GJ676A, which was already known to harbour at least one gas giant:
  • Full-orbit observations of HD189733b in the 3.6 and 4.5 micron Spitzer/IRAC channels, analysed jointly with previous 8 and 24 micron observations:http://arxiv.org/abs/1206.6887
  • Narrow band H-alpha observations of GJ1214b’s atmosphere with tunable filters on the GTC, with an ambiguous/non-constraining result:
  • Lyman-alpha observations of HD189733b with changes in the transit depth detected between the two observation epochs, interpreted as variability in the planetary atmosphere:
  • Two independent papers presenting the detection of CO in the
    day-side atmosphere of the non-transiting planet tau Bootis b,
    including measurements of the planetary mass and orbital inclination,
    with results that agree:
  • Parallax, proper motion, near-IR spectra and photometry for a
    young, dusty brown dwarf with a spectrum that has more in common with
    spectra of directly imaged exoplanets than typical field brown dwarfs:
  • A transiting hot Uranus on a ~3 day orbit around an M dwarf with
    favourable properties for follow-up characterisation:
  • Temporal variations in the evaporating atmosphere of the exoplanet HD 189733b:


  • Ground-based detection of WASP-19b’s secondary eclipse in the near-IR:
  • An article on exoplanet atmospheres written by Kevin Heng for American Scientist magazine:
  • Lab tests for a Teledyne Hawaii-2RG near-IR detector: http://arxiv.org/abs/1206.4305

can make the precision measurements needed to detect the transits of terrestrial planets or detect faint atomic or molecular species in their atmospheres:

  • Modelling of condensates that are expected to start appearing in the atmospheres of cooler T dwarfs, but which have been largely neglected until now:
  • An investigation of how realistic it is to compare measurements of light reflected from the Moon after it has passed through the Earth’s atmosphere during a lunar eclipse, and transit observations of an Earth-like exoplanet:
  • Planetary evaporation from UV/X-ray radiation:
