Ramjet Acceleration of Microscopic Black Holes Within Stellar Material

Abstract

In this work we present a case that Microscopic Black Holes (MBH) of mass $10^{16}kg$ to $3\cdot 10^{19}kg$ experience acceleration as they move within stellar material at low velocities. The accelerating forces are caused by the fact that a MBH moving through stellar material leaves a trail of hot rarified gas. The rarified gas behind a MBH exerts lower gravitational force on the MBH than the dense gas in front of it. The accelerating forces exceed the gravitational drag forces when MBH moves at Mach number $\mathcal{M}<{\mathcal{M}}_0$. The equilibrium Mach number ${\mathcal{M}}_0$ depends on MBH mass and stellar material characteristics. Our calculations open the possibility of MBH orbiting within stars including Sun at Mach number ${\mathcal{M}}_0$. At the end of this work we list some unresolved problems which result from our calculations.
