Comment on "The Mass-Radius relation for Neutron Stars in gravity" by S. Capozziello, M. De Laurentis, R. Farinelli and S. Odintsov
Stoytcho S. Yazadjiev, Daniela D. Doneva
In the present comment we discuss the qualitative and the quantitative differences between the neutron stars models in gravity presented in the recent paper \cite{Capozziell…
A gravitational wave afterglow in binary neutron star mergers
Daniela D. Doneva, Kostas D. Kokkotas, Pantelis Pnigouras
We study in detail the f-mode secular instability for rapidly rotating neutron stars, putting emphasis on supermassive models which do not have a stable nonrotating counterpart. Su…
Orbital and epicyclic frequencies around neutron and strange stars in gravity
Kalin V. Staykov, Daniela D. Doneva, Stoytcho S. Yazadjiev
According to various models, the orbital and the epicyclic frequencies of particles moving on a circular orbit around compact objects are related to the quasi-periodic oscillations…
The I-Q relations for rapidly rotating neutron stars in gravity
Daniela D. Doneva, Stoytcho S. Yazadjiev, Kostas D. Kokkotas
In the present paper we study the behavior of the normalized - relation for neutron stars in a particular class of theories of gravity, namely the gravity that i…
Gravitational wave asteroseismology of neutron and strange stars in gravity
Kalin V. Staykov, Daniela D. Doneva, Stoytcho S. Yazadjiev +1
We study the oscillations of neutron and strange stars in gravity. More precisely the nonradial -modes are examined and the differences with pure general relativity are in…
Rapidly rotating neutron stars in -squared gravity
Stoytcho S. Yazadjiev, Daniela D. Doneva, Kostas D. Kokkotas
theories of gravity are one of the most popular alternative explanations for dark energy and therefore studying the possible astrophysical implications of these theories is…
Testing General Relativity with Present and Future Astrophysical Observations
Emanuele Berti, Enrico Barausse, Vitor Cardoso +50
One century after its formulation, Einstein's general relativity has made remarkable predictions and turned out to be compatible with all experimental tests. Most of these tests pr…
