  A cold neutral and extremely dim accretion disk may be present as a remnant
of a past vigorous activity around the black hole in our Galactic Center (GC).
Here we discuss ways to detect such a disk through its interaction with
numerous stars present in the central ~0.1 parsec of the Galaxy. The first
major effect expected is X-ray and near infrared (NIR) flares arising when
stars pass through the disk. The second is eclipses of the stars by the disk.
We point out conditions under which the properties of the expected X-ray flares
are similar to those recently discovered by Chandra. Since orbits of bright
stars are now being precisely measured, the combination of the expected flares
and eclipses offers an invaluable tool for constraining the disk density, size,
plane and even direction of rotation. The winds of the O-type stars are
optically thick to free-free absorption in radio frequencies. If present near
Sgr A* core, such powerful stellar winds can modulate and even occult the radio
source.
