Velocity-Height Relation for Antimatter Meteors
Abstract
A general velocity-height relation for both antimatter and ordinary matter meteor is derived. This relation can be expressed as [{\upsilon _z}/{\upsilon _infty } = {{exp }}[ { - B/a{{exp( - }}az)}] - C/{B\upsilon _infty }\{ {1 - {{exp}}[ { - B/a{{exp( - }}az)} ]} \},] where υ z is the velocity of the meteoroid at height z, υ∞ its velocity before entrance into the Earth's atmosphere, α is the scale-height, and C parameter proportional to the atom-antiatom annihilation cross- section, which is experimentally unknown. The parameter B (B = DAϱ0/m) is the well known parameter for koinomatter (ordinary matter) meteors, D is the drag factor, ϱ0 is the air density at sea level, A is the cross sectional area of the meteoroid and m its mass. When the annihilation cross-section is zero — in the case of ordinary meteors — the parameter C is also zero and the above derived equation becomes [{\upsilon _z }/{\upsilon _infty } = {{exp }}[ { - B/a{{exp( - }}az)} ],] which is the well known velocity-height relation for koinomatter meteors. In the case in which the Universe contains antimatter in compact solid structure, the velocity-height relation can be found useful.
