Toroidal Atmospheres around Extrasolar Planets

Authors: R. E. Johnson, P. J. Huggins

Comments: 15 pages, 2 figures, PASP in press

Jupiter and Saturn have extended, nearly toroidal atmospheres composed of material ejected from their moons or rings. Here we suggest that similar atmospheres must exist around giant extrasolar planets and might be observable in a transit of the parent star. Observation of such an atmosphere would be a marker for the presence of orbiting debris in the form of rings or moons that might otherwise be too small to be detected.
