Description
The conversion of a hadronic star into a quark star occurs within two
different regimes. The first regime, characterized by turbulent
combustion, occurs on very short time scales (of the order of ms) and
it is decoupled from the neutrino cooling. In the second regime,
turbulence is not active anymore, and the conversion proceeds, on a much
longer time scale (of the order of tens of seconds), via diffusion and
production of strange quarks. At the same time, neutrino cooling is
also active. The interplay between the slow conversion of the outer
part of the star and the cooling of the newly forming quark star leads
to a plateau in the neutrino luminosity which, if observed, would
possibly represent a unique signature for the existence of quark matter compact stars.
