Astrophysical applications of the post-Tolman-Oppenheimer-Volkoff formalism
Kostas Glampedakis, George Pappas, Hector O. Silva +1
The bulk properties of spherically symmetric stars in general relativity can be obtained by integrating the Tolman-Oppenheimer-Volkoff (TOV) equations. In previous work we develope…
Relativistic stars in scalar-tensor theories with disformal coupling
Masato Minamitsuji, Hector O. Silva
We present a general formulation to analyze the structure of slowly rotating relativistic stars in a broad class of scalar-tensor theories with disformal coupling to matter. Our ap…
Neutron stars in Horndeski gravity
Andrea Maselli, Hector O. Silva, Masato Minamitsuji +1
Horndeski's theory of gravity is the most general scalar-tensor theory with a single scalar whose equations of motion contain at most second-order derivatives. A subsector of Hornd…
Compact objects in Horndeski gravity
Hector O. Silva, Andrea Maselli, Masato Minamitsuji +1
Horndeski gravity holds a special position as the most general extension of Einstein's theory of general relativity with a single scalar degree of freedom and second-order field eq…
Low-mass neutron stars: universal relations, the nuclear symmetry energy and gravitational radiation
Hector O. Silva, Hajime Sotani, Emanuele Berti
The lowest neutron star masses currently measured are in the range , but these measurement have either large uncertainties or refer to isolated neutron stars. The…
