Query: Characterization of the atmosphere of the hot Jupiter HAT-P-32Ab and the
  M-dwarf companion HAT-P-32B   We report secondary eclipse photometry of the hot Jupiter HAT-P-32Ab, taken
with Hale/WIRC in H and Ks bands and with Spitzer/IRAC at 3.6 and 4.5 micron.
We carried out adaptive optics imaging of the planet host star HAT-P-32A and
its companion HAT-P-32B in the near-IR and the visible. We clearly resolve the
two stars from each other and find a separation of 2.923" +/- 0. 004" and a
position angle 110.64 deg +/- 0.12 deg. We measure the flux ratios of the
binary in g' r' i' z' and H & Ks bands, and determine Teff = 3565 +/- 82 K for
the companion star, corresponding to an M1.5 dwarf. We use PHOENIX stellar
atmosphere models to correct the dilution of the secondary eclipse depths of
the hot Jupiter due to the presence of the M1.5 companion. We also improve the
secondary eclipse photometry by accounting for the non-classical,
flux-dependent nonlinearity of the WIRC IR detector in the H band. We measure
planet-to-star flux ratios of 0.090 +/- 0.033%, 0.178 +/- 0.057%, 0.364 +/-
0.016%, and 0.438 +/- 0.020% in the H, Ks, 3.6 and 4.5 micron bands,
respectively. We compare these with planetary atmospheric models, and find they
prefer an atmosphere with a temperature inversion and inefficient heat
redistribution. However, we also find that the data are equally well-described
by a blackbody model for the planet with Tp = 2042 +/- 50 K. Finally, we
measure a secondary eclipse timing offset of 0.3 +/- 1.3 min from the predicted
mid-eclipse time, which constrains e = 0.0072 +0.0700/-0.0064 when combined
with RV data and is more consistent with a circular orbit.
