Web11 de abr. de 2024 · The effects on the speed of sound in neutron stars due to the presence of hyperons and a phase transition to deconfined quark matter is investi-gated. For this purpose a composite description within the covariant field theory is used, it consists of different models for the hadronic and for the unbound quark configurations. Webp-modes or pressure modes, are determined by the local sound speed in the star, hence they are also often referred to as acoustic modes. Greatly dependent on the density and temperature of the neutron star, they are powered by internal pressure fluctuations in the stellar medium. Typical predicted periods lie around 0.1 ms. chester nissan dealership https://petersundpartner.com
