Dynamical instability of polytropic spheres in spacetimes with a cosmological constant
Camilo Posada, Jan Hladík, Zdenek Stuchlík
The dynamical instability of relativistic polytropic spheres, embedded in a spacetime with a repulsive cosmological constant, is studied in the framework of general relativity. We…
Where is Love? Tidal deformability in the black hole compactness limit
Cecilia Chirenti, Camilo Posada, Victor Guedes
One of the macroscopically measurable effects of gravity is the tidal deformability of astrophysical objects, which can be quantified by their tidal Love numbers. For planets and s…
Radial instability of trapping polytropic spheres
Jan Hladík, Camilo Posada, Zdeněk Stuchlík
We complete the stability study of general relativistic spherically symmetric polytropic perfect fluid spheres, concentrating attention to the newly discovered polytropes containin…
