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…
Short GRB 090510: a magnetized neutron star binary merger leading to a black hole
J. A. Rueda, R. Ruffini, Yu Wang
We model the short gamma-ray bursts (GRB) 090510 as the product of a magnetized neutron star (NS) binary merger. Accounting for the NS critical mass constraint given by the mass of…
On the formation of strange quark stars from supernova in compact binaries
L. M. Becerra, F. Cipolletta, A. Drago +4
Strange quark stars (SQSs), namely compact stars entirely composed of deconfined quark matter, are characterized by similar masses and compactness to neutron stars (NSs) and have b…
Can the central compact object in HESS J1731--347 be indeed the lightest neutron star observed?
Shu-Rui Zhang, Jorge A. Rueda, Rodrigo Negreiros
The exceptionally low mass of for the central compact object (CCO) XMMU J173203.3 -- 344518 (XMMU J1732) in the supernova remnant (SNR) HESS J1731 -…
