Accretion of dark energy candidates following redshift parametrization type equation of state: Horava–Lifshitz gravity
Abstract In this article, accretion of particular dark energy candidates is studied. These dark energy models possess equation of state dependent on redshift and some free parameters. Central gravitating object for this accretion model is chosen to be the Kehagias Sfetsos black hole sitting in Horava Gravity. Four special redshift parametrization models, viz. Chevallier–Polarski–Linder, Jassal–Bagala–Padmanabhan, Barboza–Alcaniz and Barboza–Alcaniz–Zhu–Silva are picked to study different accretion properties. Formation of critical point and related radial infalling speed, sonic speed, different arbitrary parameters’ values etc are obtained. Mass growth curves are plotted. The rate of growth is followed to depend on the dark matter’s behavior as well as the free parameters of dark energy models. Future loss in mass is noted for some of the chosen dark energy models.
