Delayed Detonation Thermonuclear Supernovae with an Extended Dark Matter Component

We present simulations of thermonuclear supernovae admixed with an extended component fermionic cold dark matter. consider the explosion a Chandrasekhar-mass white dwarf using deflagration model deflagration-detonation transition spherical symmetry. The matter is comparable in size that normal matter, and so system described by two-fluid, one-dimensional Eulerian hydrodynamics. leaves all trapped as remnant compact star our considered models. presence lengthens phase to produce more thermo-neutrinos similar amounts iron-group elements compared those ordinary explosions no admixture. models dimmer broader light curves, which challenge role standard candles cosmic distance measurement. Our results also suggest formation path objects mimic sub-solar-mass black holes gravitational sources, through near-solar-mass supernovae.
