WIMP Annihilation and Cooling of Neutron Stars
Chris Kouvaris
TL;DR
This paper investigates how WIMP annihilation influences neutron star temperatures, suggesting it could maintain a baseline temperature of around 10,000 K in older stars, impacting their thermal evolution.
Contribution
It introduces the idea that WIMP annihilation can significantly affect neutron star cooling, providing a new perspective on their thermal history.
Findings
WIMP annihilation can sustain neutron star temperatures around 10,000 K.
Older neutron stars may not cool below a certain temperature due to WIMP effects.
The temperature plateau occurs in stars older than 10 million years.
Abstract
We study the effect of WIMP annihilation on the temperature of a neutron star. We shall argue that the released energy due to WIMP annihilation inside the neutron stars, might affect the temperature of stars older than 10 million years, flattening out the temperature at K for a typical neutron star.
