Jupiter and Saturn have extended, nearly toroidal atmospheres composed ofmaterial ejected from their moons or rings. Here we suggest that similaratmospheres must exist around giant extrasolar planets and might be observablein a transit of the parent star. Observation of such an atmosphere would be amarker for the presence of orbiting debris in the form of rings or moons thatmight otherwise be too small to be detected.Comment: 15 pages, 2 figures, PASP in pres
