Extending the Pulsar radio population through Quantum Vacuum Cherenkov Emission
Tales A. O. Gomes, Sergei V. Bulanov, Jaziel G. Coelho +3
The presence of some radio pulsars within and below the so-called ``death valley'' in the -- diagram challenges the standard pair-cascade models based on curvature radi…
A post-hypercritical accretion small-scale dynamo in newborn neutron stars
David F. Bambague, Cristian G. Bernal, J. A. Rueda
Hypercritical fallback accretion can advect the surface magnetic field of a newborn neutron star into the newly accreted outer layers. Before this material joins the solid crust an…
Optical transients from non-explosive double white-dwarf mergers: the case of a central neutron star remnant
M. M. Ridha Fathima, Alexandre M. R. Almeida, Mattia Bulla +3
Discoveries of ultra-massive magnetic white dwarfs (WDs) and peculiar pulsars have been proposed to originate in double white dwarf (DWD) mergers. There are three possible post-mer…
Double White Dwarf Mergers as Progenitors of Long-Period Transients
Manuel Malheiro, Sarah V. Borges, Jaziel G. Coelho +6
There is an ongoing discussion in the literature on the nature of long-period transients (LPTs), radio-emitting sources with periods ranging from hundreds to tens of thousands of s…
