    Members of the NASA Astrobiology Institute based at NASA Ames Research Center team have published a paper describing a thermal model applied to light curves of planet-bearing stars. The model accurately reproduces much of the large-scale data of existing full-orbit photometry data captured by the Spitzer Space Telescope, including the timescale of heating/cooling, the time positions of minimum and maximum flux, and depths of transits and secondary eclipses.

    “Reassessing Exoplanet Light Curves with a Thermal Model” is published in the Astronomical Journal.
