Wave propagation and shock formation in the most general scalar-tensor theories
Norihiro Tanahashi, Seiju Ohashi
This work studies wave propagation in the most general scalar-tensor theories, particularly focusing on the causal structure realized in these theories and also the shock formation…
Violation of cosmic censorship in the gravitational collapse of a dust cloud in five dimension
Ryosuke Mizuno, Seiju Ohashi, Tetsuya Shiromizu
We analyze the null geodesic equations in five dimensional spherically symmetric spacetime with collapsing inhomogeneous dust cloud. By using a new method, we prove the existence a…
Spherical collapse of inhomogeneous dust cloud in the Lovelock theory
Seiju Ohashi, Tetsuya Shiromizu, Sanjay Jhingan
We study gravitational collapse of a spherically symmetric inhomogeneous dust cloud in the Lovelock theory without cosmological constant. We show that the final fate of gravitation…
A perturbative no-hair of form fields for higher dimensional static black holes
Tetsuya Shiromizu, Seiju Ohashi, Kentaro Tanabe
In this paper we examine the static perturbation of p-form field strengths around higher dimensional Schwarzschild spacetimes. As a result, we can see that the static perturbations…
