An artificial meteors database as a test for the presence of weak showers
We have constructed an artificial meteor database resembling in all details the real sample collected by the observers of the Comets and Meteors Workshop in the years 1996-1999. The artificial database includes the sporadic meteors and also events from the following showers: Perseids, Aquarid complex, α-Capricornids, July Pegasids and Sagittarids. This database was searched for the presence of ...
متن کاملOn Meteors, Earthworms and Wimps
We study a model of mass redistribution on a finite graph. We address the questions of convergence to equilibrium and the rate of convergence. We present theorems on the distribution of empty sites and the distribution of mass at a fixed vertex. These distributions are related to random permutations with certain peak sets.
متن کاملPhotoacoustic Sounds from Meteors
Concurrent sound associated with very bright meteors manifests as popping, hissing, and faint rustling sounds occurring simultaneously with the arrival of light from meteors. Numerous instances have been documented with -11 to -13 brightness. These sounds cannot be attributed to direct acoustic propagation from the upper atmosphere for which travel time would be several minutes. Concurrent soun...
متن کاملTunguska genetic anomaly and electrophonic meteors
One of great mysteries of the Tunguska event is its genetic impact. Some genetic anomalies were reported in the plants, insects and people of the Tunguska region. Remarkably, the increased rate of biological mutations was found not only within the epicenter area, but also along the trajectory of the Tunguska Space Body (TSB). At that no traces of radioactivity were found, which could be reliabl...
متن کاملPlanetary Satellites, Asteroids, Comets and Meteors
Asteroids, mainly rocky or metallic bodies in the inner solar system, orbit the Sun in various distinct populations (planet-crossers, main-belt asteroids, trans-Neptunian Edgeworth-Kuiper belt objects, Centaurs in the outer planetary region) between which there are transfers over substantial timescales. For example the main belt is the main reservoir replenishing the Earth-crossing asteroids, t...
