Two-Step Bose-Einstein Condensation of an ideal Magnetized Charged Bosonic gas under neutron star-like conditions

Amanda Castillo Ayon, Gabriel Gil Pérez, Aurora Pérez Martinez +4

We study the thermodynamic properties of a non-interacting, relativistic gas of charged scalar bosons in a uniform magnetic field, including both statistical and vacuum contributio…

SPLUS J142445.34-254247.1: An R-Process Enhanced, Actinide-Boost, Extremely Metal-Poor star observed with GHOST

Vinicius M. Placco, Felipe Almeida-Fernandes, Erika M. Holmbeck +33

We report on the chemo-dynamical analysis of SPLUS J142445.34-254247.1, an extremely metal-poor halo star enhanced in elements formed by the rapid neutron-capture process. This sta…

2MASS J18082002-5104378: The brightest (V=11.9) ultra metal-poor star

Jorge Melendez, Vinicius M. Placco, Marcelo Tucci-Maia +3

Context. The most primitive metal-poor stars are important for studying the conditions of the early galaxy and are also relevant to big bang nucleosynthesis. Aims. Our objective is…
