On (Not)-Constraining Heavy Asymmetric Bosonic Dark Matter

Understand

Recently, constraints on bosonic asymmetric dark matter have been imposed based on the existence of old neutron stars excluding the dark matter masses in the range from $\sim 2$ keV up to several GeV.

• The constraints are based on the star destruction scenario where the dark matter particles captured by the star collapse forming a black hole that eventually consumes the host star.
• In addition, there were claims in the literature that similar constraints can be obtained for dark matter masses heavier than a few TeV.
• Here we argue that it is not possible to extend to these constraints.
