[1909.01139] Charged Gravastars in Rastall-Rainbow Gravity
Web11 de oct. de 2024 · Also, we propose gravastars as the solution of the "pair-instability" effect and a possible explanation for the observed masses of the compact objects, before the collapse, from the gravitational signal GW190521, since in the formation of a gravastar there aren't mass restrictions. Submission history From: Ioannis Antoniou [ view email ] Web5 de nov. de 2024 · In this paper, we discuss the geometry of gravastar which is internally charged in f (R,T) gravity conceding the conformal motion. For R+2\beta T gravity model, … body world display

Webblack hole of the same mass and thus can be used to discern, beyond dispute, a gravastar from a black hole. PACS numbers: 04.40.Dg, 04.30.Nk, 04.25.Nx (Some figures in this article are in colour only in the electronic version) 1. Introduction The gravastar model was proposed by Mazur and Mottola [1] and has attracted attention as Web2 de sept. de 1997 · A new final endpoint of complete gravitational collapse is proposed. By extending the concept of Bose–Einstein condensation to gravitational systems, a static, spherically symmetric solution to Einstein’s equations is obtained, characterized by an interior de Sitter region of p=−ρ gravitational vacuum … Webwhere M˙ is the mass accretion rate and L is the total luminosity. Thus, from equation (1), we estimate that a gravastar which starts at zero temperature and rapidly accretes a mass ∆mM⊙ will be heated to a temperature as observed at infinity of T h ≃ M⊙c2 Um2 1/3 ξ1/3 ∆m m 1/3 ≃ 3.1× 106m−2/3ξ1/3 ∆m m 1/3 K, (3) where m is ... glitter dip powder nails ideas
