Search for Na in novae supported by a novel method for measuring femtosecond nuclear lifetimes
C. Fougères, F. de Oliveira Santos, J. José +58
Classical novae are thermonuclear explosions in stellar binary systems, and important sources of Al and Na. While gamma rays from the decay of the former radioisotope…
Testing Horndeski gravity with S2 star orbit
Riccardo Della Monica, Ivan de Martino, Daniele Vernieri +1
We have explored a completely new and alternative way to restrict the parameter space of Horndeski theory of gravity. Using its Newtonian limit, it is possible to test the theory a…
Some disquisitions on cosmological 2-form dualities
Katsuki Aoki, Jose Beltrán Jiménez, David Figueruelo
In this work we study different aspect of self-interacting 2-form fields with special emphasis in their cosmological applications. We provide the explicit construction of how massl…
Strong magnetic fields and pasta phases revisited
Luigi Scurto, Helena Pais, Francesca Gulminelli
In this work, we compute the structure and composition of the inner crust of a neutron star in the presence of a strong magnetic field, such as it can be found in magnetars. To det…
Parametric Resonances in Axionic Cosmic Strings
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Jose M. Queiruga +1
In this letter we uncover a new parametric resonance of axionic cosmic strings. This process is triggered by the presence on the string of internal mode excitations that resonantly…
Remarks on propagating waves in non-linear vacuum electrodynamics
M. Ángeles Pérez-García, A. Pérez Martínez, E. Rodríguez Querts
Using the quadratic expansion in the photon fields of Euler-Heisenberg (EH) non-linear electrodynamics (NLED) Lagrangian model we study relevant vacuum properties in a scenario inv…
