“When modeling the structure of compact stars, the presence of magnetic fields poses a number of questions about the micro and macrophysics treatment of the system. Here, we discuss a model based in the so-called γ-metric to describe anisotropic magnetized compact stars.”
Keywords: compact stars

“A personal view of the history of the Theoretical Physics Department (DFT) at ICIMAF (former ININTEF) is presented. The current Department was originally called Theoretical Physics Group (GFT).”

“We briefly review the history and achievements of the Department of Theoretical Physics (DFT) of the ICIMAF since its foundation in 1976. The data and opinions of former and current members of the DFT were taken from a series of interviews made to the participants of the scientific conference FT-45, held virtually in March 2021, to celebrate the 45th anniversary of the DFT.”

“In this work we study stable configurations of magnetized strange stars using an axially symmetric metric in spherical coordinates and calculate its observables (masses, radii and mass quadrupole moment).”

“The experimental measurements on flavour physics, in tension with Standard Model predictions, exhibit large sources of Lepton Flavour Universality violation. An analysis of the effects of the global fits to the Wilson coefficients, assuming a model independent effective Hamiltonian approach, is summarized.”

“We study the thermodynamic properties of a relativistic magnetized neutral vector boson gas at any temperature. We compare the results with the low temperature (LT) and the non relativistic (NR) descriptions of this gas.”

“The main physical ideas about Dynamical Gravastars, are briefly presented in common with the main properties of their field configuration. Also, we estimate the place that these solutions should take within the current astrophysical ideas for describing the super-massive galaxy centers and stars.”
