# Expansion and contraction of accretion disks of a rotating thermal BIon in a Rindler space-time

## TL;DR

This paper studies how accretion disks in a rotating BIon within Rindler space-time expand or contract due to rotation and acceleration effects, revealing dynamic area changes and different disk types.

## Contribution

It introduces a model of rotating BIons in Rindler space-time, analyzing the evolution and area dynamics of accretion disks connected by a wormhole, which is a novel approach.

## Key findings

- Increasing rotation velocity enlarges one disk while shrinking the other.
- Four distinct types of accretion disks are identified in Rindler space-time.
- The study links acceleration in Rindler space to disk evolution behaviors.

## Abstract

In this paper, we consider the evolution of accretion disks of a rotating BIon in a Rindler space-time. This space-time emerges because of the acceleration of the disks in a BIon. A BIon is constructed from a pair of accretion disks that are connected by a wormhole. We will show that in a rotating BIon, by increasing the rotation velocity, the area of one accretion disk grows, while the area of the other shrinks. Also, we consider four types of accreion disks which are produced in a Rindler space-time.
