Slowly rotating ultracompact Schwarzschild star in the gravastar limit
Philip Beltracchi, Camilo Posada
We reconsider the problem of a slowly rotating homogeneous star, or Schwarzschild star, when its compactness goes beyond the Buchdahl bound and approaches the gravastar limit $R\to…
Slowly rotating Tolman VII solution
Camilo Posada, Zdeněk Stuchlík
We present a model of a slowly rotating Tolman VII (T-VII) fluid sphere, at second order in the angular velocity. The structure of this configuration is obtained by integrating the…
Extended Tolman III and VII solutions in gravity: Models for neutron stars and supermassive stars
Thomas D. Pappas, Camilo Posada, Zdeněk Stuchlík
In the context of linear gravity, where is the Ricci scalar, is the trace of the energy-momentum tensor, and is a dimensionl…
New interior model of neutron stars
Camilo Posada, Jan Hladík, Zdeněk Stuchlík
The Tolman VII solution is considered by some as one of the few analytical solutions to Einstein's equations, which describes approximately well the interior of neutron stars (NSs)…
Tidal deformability of ultracompact Schwarzschild stars and their approach to the black hole limit
Camilo Posada
A well-known result in general relativity is that the tidal Love numbers of black holes vanish. In contrast, different configurations to a black hole may have non-vanishing Love nu…
Neutrino trapping in extremely compact Tolman VII spacetimes
Zdeněk Stuchlík, Jan Hladík, Jaroslav Vrba +1
Extremely compact objects trap gravitational waves or neutrinos, assumed to move along null geodesics in the trapping regions. The trapping of neutrinos was extensively studied for…
