Query: The Effect of Condensates on the Characterization of Transiting Planet
  Atmospheres with Transmission Spectroscopy   Through a simple physical argument we show that the slant optical depth
through the atmosphere of a "hot Jupiter" planet is 35-90 times greater than
the normal optical depth. This not unexpected result has direct consequences
for the method of transmission spectroscopy for characterizing the atmospheres
of transiting giant planets. The atmospheres of these planets likely contain
minor condensates and hazes which at normal viewing geometry have negligible
optical depth, but at slant viewing geometry have appreciable optical depth
that can obscure absorption features of gaseous atmospheric species. We
identify several possible condensates. We predict that this is a general
masking mechanism for all planets, not just for HD 209458b, and will lead to
weaker than expected or undetected absorption features. Constraints on an
atmosphere from transmission spectroscopy are not the same as constraints on an
atmosphere at normal viewing geometry.
