Descripción
PASS, the Permanent All Sky Survey is a project to survey the entire
visible sky for the presence of transits by extrasolar planets. The
instrument would consist of one or two fixed arrays of wide-angle
cameras, that would permanently take images of the entire visible sky
more then 30 deg above horizon. A design sutdy consisting of 15 cameras
in each array, with optics based on SLR camera lenses is presented.
Simulations of the camera system show that the brightness limit for
transit detections of giant planets will be 10th-11th magnitude. One
such instrument located around 30 deg N should allow the surveying of
about 150 000 stars, with a southern declination limit of 18 deg. With
the addition of a similar instrument in the opposite hemisphere, a
coverage of the entire sky can be obtained (250 000 stars), and coverage
is relatively uniform over all declinations. The result would be a
complete catalog of all transiting giant planets around bright stars,
with an estimated 120 planet detections. The sample stars' high
brightness would make transits detected by PASS the best suited ones for
follow-up studies from ground and space missions.
