Abstract

It is shown that both general arguments and a preliminary evolutionary calculation suggest that stars in the (stellar-to-solar) mass ratio range from 7 to 10 develop cores of about 1.45 solar masses, which evolve toward high densities after burning up all their carbon. Even if detonation finally occurs, these cores are not expected to be disrupted. It is suggested that more attention be given to this mass ratio range, which seems promising for the explanation of pulsar formation.
