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…

Brans-Dicke unimodular gravity
Alexandre M. R. Almeida, Júlio C. Fabris, Mahamadou Hamani Daouda +3
We propose a unimodular version of the Brans-Dicke theory designed with a constrained Lagrangian formulation. The resulting field equations are traceless. The vacuum solutions in t…
