Abstract
Black holes below Chandrasekhar mass limit (1.4 $M_{\odot}$) can not be produced via any standard stellar evolution. Recently, gravitational wave experiments have also discovered unusually low mass black holes whose origin is yet to be known. We propose a simple yet novel formation mechanism of such low mass black holes. Non-annihilating particle dark matter, owing to their interaction with stellar nuclei, can gradually accumulate inside compact stars, and eventually swallows them to low mass black holes, ordinarily impermissible by the Chandrasekhar limit. We point out several avenues to test this proposal, concentrating on the cosmic evolution of the binary merger rates.

Reports on this Submission
Strengths
1. This submission addresses an important question in latest astrophysics, to explain the possible existence of sub-Solar black hole with dark matter particles.
2. The manuscript is written in a clear way , summarising their studies on the formation of such transmuted black holes, as well as how such black holes can be distinguished from other mechanisms.
Weaknesses
1. There exist a few grammar issues in the submission, which should be corrected in later editing.
Report
This manuscript meets the criteria of publishing as a proceeding, as their results are important enough, as well as nicely presented.
Requested changes
None.
