Stability of relativistic stars with scalar hairs
Ryotaro Kase, Rampei Kimura, Seiga Sato +1
We study the stability of relativistic stars in scalar-tensor theories with a nonminimal coupling of the form , where depends on a scalar field and is the Ricci…

Neutron star cooling in modified gravity theories
Akira Dohi, Ryotaro Kase, Rampei Kimura +2
We study thermal evolution of isolated neutron stars in scalar-tensor theories for the first time. Whether the rapid cooling due to the direct Urca process occurs or not is an inte…

Massive gravity with non-minimal coupling
A. Emir Gumrukcuoglu, Rampei Kimura, Kazuya Koyama
We propose new massive gravity theories with 5 dynamical degrees of freedom. We evade uniqueness theorems regarding the form of the kinetic and potential terms by adopting the "gen…
