Query: Cooling of Neutron Stars admixed with Light Dark Matter: a case study   Neutron Stars (NSs) are born as hot, lepton-rich objects that evolve
according to the standard paradigm through subsequent stages where they radiate
the excess of energy by emitting, first, neutrinos and, later on, photons.
Current descriptions based on Standard Model calculations cannot fully explain
all the existing cooling data series for the dozens of objects that have been
reported. In this work, we consider the intriguing possibility that cooling NSs
could be actually admixed with a fraction of light dark matter (LDM), $\chi$.
We focus on a particular case study assuming a generic light candidate with
mass $m_\chi=0.1$ $\rm GeV/c^2$ that undergoes self-annihilating reactions
through pseudoscalar mediators producing neutrinos in the final state. We
include one additional feature, allowing thermal conduction from LDM while
inside the dark core. By performing simulations of the temperature evolution in
the NS, we find that cooling patterns could be distorted by the presence of LDM
and discuss these results in light of their observability.
