# Solar luminosity bounds on mirror matter

## TL;DR

This paper derives bounds on mirror dark matter by analyzing its impact on solar luminosity, estimating heat transfer to the mirror sector, and calculating its effect on the Sun's energy output.

## Contribution

It introduces a method to constrain mirror matter using solar luminosity data, combining analytic estimates with detailed numerical calculations.

## Key findings

- Mirror matter increases the Sun's energy requirements.
- Heat transfer to mirror sector is constrained by solar luminosity observations.
- Numerical bounds on mirror matter concentration are established.

## Abstract

We present bounds on mirror dark matter scenario derived by using the effect of mirror matter on the luminosity of the Sun. In the perturbative regime where the mirror matter concentration is small relative to the ordinary matter we estimate the heat transfer from ordinary matter to the mirror sector by simple analytic consideration. That amount of heat transfer is radiated via mirror photons and increases the required energy production in order to maintain the observed luminosity. We then present more detailed numerical calculations of the total amount of this energy transfer.
