Ramjet Acceleration of Microscopic Black Holes Within Stellar Material

TL;DR

This paper proposes that microscopic black holes can accelerate within stellar material due to asymmetric gas trails, potentially allowing them to orbit stars like the Sun, which challenges previous assumptions about their behavior.

Contribution

It introduces a novel mechanism for MBH acceleration within stars based on gas trail effects, expanding understanding of their dynamics in stellar environments.

Findings

MBHs can experience acceleration due to gas trail effects.

The equilibrium Mach number depends on MBH mass and stellar properties.

MBHs may orbit within stars like the Sun under certain conditions.

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.
