Efrat Sabach and Noam Soker examine rare evolutionary routes of binary systems where the initially more massive primary star forms a white dwarf (WD), while the secondary star accretes mass from the evolved primary and later terminates as acore-collapse supernova (CCSN). In such a WD–NS (neutron star) reverse evolution a NS or a potential NS-progenitor massive core is formed after the WD. These SN explosions are likely to be preceded by strong interaction of the WD with the giant secondary’s core, leading to an Intermediate-Luminosity Optical Transient (ILOT). Paper published in MNRAS.
