[49.11] Extrasolar Meteors from Debris Disks

J.C. Weingartner, N. Murray (CITA)

Grains in circumstellar debris disks can be ejected from the system following a gravitational interaction with a planet, and can ultimately be observed as meteors in Earth's atmosphere. The particle flux at Earth depends on the rate at which grains are ejected, the distance and velocity of the source with respect to the Sun, and the probability that the grains survive the trip. Our estimates suggest that nearby Vega-like stars could yield detectable signatures in the distribution of extrasolar meteors observed with radar facilities. We acknowledge funding from NSERC of Canada.
