Dark Matter in White Dwarfs: Implications for Their Structure
SÃlvia P. Nunes, José D. V. Arbañil, Juan M. Z. Pretel +1
White Dwarfs (WDs), the final evolutionary stage of most stars, are frequently modeled considering only a dense plasma matter. However, their potential interaction with dark matter…

Neutron stars with a dark-energy core from the Chaplygin gas
Juan M. Z. Pretel, Mariana Dutra, Sergio B. Duarte
We analyze the effect of a Chaplygin dark fluid (CDF) core on neutron stars (NSs). To address this study, we focus on the relativistic structure of stellar configurations composed…

Dark energy effects on realistic neutron stars
Juan M. Z. Pretel, Sergio B. Duarte, José D. V. Arbañil +2
By considering realistic equations of state (EoSs) to describe the ordinary matter of the stellar crust, in this study, we explore the effect of a dark energy core, made of Chaplyg…
