J/A+A/610/A55       Spitzer secondary eclipses of Qatar-1b       (Garhart+ 2018)

Spitzer secondary eclipses of Qatar-1b. Garhart E., Deming D., Mandell A., Knutson H., Fortney J.J. <Astron. Astrophys. 610, A55 (2018)> =2018A&A...610A..55G (SIMBAD/NED BibCode)

There have also been indications that the orbit may be slightly eccentric, possibly forced by another planet in the system. We investigate the day side temperature and orbital eccentricity using secondary eclipse observations with Spitzer. We observed the secondary eclipse with Spitzer/IRAC in subarray mode, in both 3.6 and 4.5um wavelengths. We used pixel-level decorrelation to correct for Spitzer's intra-pixel sensitivity variations and thereby obtain accurate eclipse depths and central phases. Description: Lightcurve data for the observed eclipse of Qatar-1b in two Spitzer/IRAC channels at 3.6 (ch1) and 4.5 (ch2) microns. The data has been binned for clarity and normalized to unity in eclipse as it appears in the paper. The fitted eclipse data is the best fit solution with the intra-pixel effects removed and is unbinned. The BJD(TDB), phase, and binned phase are also provided.
