The variation of the electromagnetic coupling and quintessence
M. C. Bento, R. Gonzalez Felipe
The properties of quintessence are examined through the study of the variation of the electromagnetic coupling. We consider two simple quintessence models with a modified exponenti…
Stability window and mass-radius relation for magnetized strange quark stars
R. Gonzalez Felipe, A. Perez Martinez
The stability of magnetized strange quark matter (MSQM) is investigated within the phenomenological MIT bag model, taking into account the variation of the relevant input parameter…
A Simple Quintessence Model
M. C. Bento, R. Gonzalez Felipe, N. M. C. Santos
A simple model of quintessential inflation with the modified exponential potential is analyzed in the braneworld context. Considering reheating via instant…
Brane assisted quintessential inflation with transient acceleration
M. C. Bento, R. Gonzalez Felipe, N. M. C. Santos
A simple model of quintessential inflation with the modified exponential potential exp(-αϕ) [A + (ϕ-ϕ_0)^2] is analyzed in the braneworld context. Considering reheating via instant…
Magnetized strange quark matter and magnetized strange quark stars
R. Gonzalez Felipe, A. Perez Martinez, H. Perez Rojas +1
Strange quark matter could be found in the core of neutron stars or forming strange quark stars. As is well known, these astrophysical objects are endowed with strong magnetic fiel…
Braneworld inflation from an effective field theory after WMAP three-year data
M. C. Bento, R. Gonzalez Felipe, N. M. C. Santos
In light of the results from the WMAP three-year sky survey, we study an inflationary model based on a single-field polynomial potential, with up to quartic terms in the inflaton f…
Quantum instability of magnetized stellar objects
R. Gonzalez Felipe, H. J. Mosquera Cuesta, A. Perez Martinez +1
The equations of state for degenerate electron and neutron gases are studied in the presence of magnetic fields. After including quantum effects to study the structural properties…
