We study neutrino production, propagation, and oscillations within an
extremely magnetized background of finite-temperature nuclear matter. We focus
on three particularly interesting cases and identify the astrophysical
scenarios where such a signal may be found. The first case involves nuclear
matter with electrons, and it is found during the central-engine stage of,
both, short and long gamma-ray bursts (GRBs). Thus, for the short GRB case it
will also be associated to gravitational-wave events where there is an
electromagnetic counterpart (e.g., GW170817). The second and third scenarios
involve the presence of strange-quark matter (SQM). The second scenario occurs
if SQM can become negatively charged (SQM$^-$; which may only occur at high
pressure) and, thus, it is embedded in a positron plasma. The third case may be
found at the interphase where SQM transitions from positive (SQM$^+$) to
negative; here, positrons and electrons may constantly annihilate and give a
distinctive neutrino signature. Therefore, this may also be a signature of the
existence of strange stars. Given the wide range of magnetic fields we find in
the literature, we also briefly discuss the maximum limit that a stellar mass
compact object may posses.
