  bibo_abstract:
  - We revisit the possibility of detecting an extrasolar planet around a background
    star as it crosses the fold caustic of a foreground binary lens. During such an
    event, the planet's flux can be magnified by a factor of ~100 or more. The detectability
    of the planet depends strongly on the orientation of its orbit relative to the
    caustic. If the source star is inside the intercaustic region, detecting the caustic-crossing
    planet is difficult against the magnified flux of its parent star. In the more
    favorable configuration, when the star is outside the intercaustic region when
    the planet crosses the caustic, a close-in Jupiter-like planet around a Sun-like
    star at a distance of 8 kpc is detectable in 8 minute integrations with a 10 m
    telescope at maximal signal-to-noise ratio (S/N) ~15 for phase angle ϕ ~ 10°.
    In this example, we find further that the presence of methane, at its measured
    abundance in Jupiter, and/or water, sodium, and potassium, at the abundances expected
    in theoretical atmosphere models of close-in Jupiters, could be inferred from
    a nondetection of the planet in strong broad absorption bands at 0.6-1.4 μm caused
    by these compounds, accompanied by a S/N ~ 10 detection in adjacent bands. We
    conclude that future generations of large telescopes might be able to probe the
    composition of the atmospheres of distant extrasolar planets.@eng
