✦ Synopsis

A general velocity-height relation for both antimatter and ordinary matter meteor is derived. This relation can be expressed as

where uZ is the velocity of the meteoroid at height z, u, its velocity before entrance into the Earth's atmosphere, a is the scale-height, and C parameter proportional to the atom-antiatom annihilation crosssection, which is experimentally unknown. The parameter B (B = DAp,/m) is the well known parameter for koinomatter (ordinary matter) meteors, D is the drag factor, pc 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 v B -= exp [ 1 --exp(-az) , Ucc a 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.
