Compact stars with strongly coupled quark matter in a strong magnetic field

Abstract: Some time ago we have derived from the QCD Lagrangian an equation of state (EOS) for the cold quark matter, which can be considered an improved version of the MIT bag model EOS.Compared to the latter, our equation of state reaches higher values of the pressure at comparable baryon densities. This feature is due to perturbative corrections and also to non-perturbative effects. Later we applied this EOS to the study of compact stars, discussing the absolute stability of quark matter and computing the mass-radius… Show more

“…However, as we can see in figure 3.1 the difference between the parallel and perpendicular pressures is roughly zero until a certain critical point where it starts to grow very fast. Given this behavior we decided [1] to utilize the TOV equations (TolmanOppenheimer-Volkof) and to present our results and predictions for the stellar structure using both the parallel and perpendicular pressure respectively as an inner and outer limit. That assumption is well explained in figure 3.2.…”

“…Vamos agora introduzir um campo magnético clássico, com magnitude e sentido constante: B = Bẑ (e então A µ = (0, yB, 0, 0)) e também um outro campo espinorial para representar os elétrons. No estudo de estrelas compactas eles são necessários para garantir a neutralidade de carga [44].…”
