Contribution
It introduces new simulations of WIMP effects on stellar evolution near black holes, emphasizing the impact on low-mass stars with the DarkStars code.
Findings
Low-mass stars are most affected by WIMP annihilation.
WIMP effects could influence observational signatures.
Preliminary results suggest significant stellar structure changes.
Abstract
Recent work has indicated that WIMP annihilation in stellar cores has the potential to contribute significantly to a star's total energy production. We report on progress in simulating the effects of WIMP capture and annihilation upon stellar structure and evolution near supermassive black holes, using the new DarkStars code. Preliminary results indicate that low-mass stars are the most influenced by WIMP annihilation, which could have consequences for upcoming observational programs.
