# Accretion onto a noncommutative inspired Schwarzschild black hole

## TL;DR

This paper studies how noncommutative geometry influences matter accretion onto Schwarzschild black holes, revealing modifications in accretion rates, sonic radius, and thermal profiles due to noncommutativity.

## Contribution

It derives modified accretion equations for noncommutative inspired Schwarzschild black holes and analyzes the impact of noncommutativity on accretion dynamics and thermal environment.

## Key findings

- Accretion rate increases with noncommutative parameter.
- Sonic radius decreases as noncommutativity grows.
- Sound speed at sonic point increases with noncommutativity.

## Abstract

In this paper we investigate the problem of ordinary baryonic matter accretion onto the noncommutative geometry inspired Schwarzschild black hole. The fundamental equations governing the spherically symmetric steady state matter accretion are deduced. These equations are seen to be modified due to the presence of noncommutativity. The matter accretion rate is computed and is found to increase rapidly with the increase in strength of the noncommutative parameter. The sonic radius reduces while the sound speed at the sonic point increases with the increase in the strength of noncommutativity. The profile of the thermal environment is finally investigated below the sonic radius and at the event horizon and is found to be affected by noncommutativity.
