Exact solutions for static spherically symmetric spacetime with a perfect fluid in Rastall theory
Yoshimune Tomikawa, Ichika Obara, Takumi Orimo
The paper derives exact static, spherically symmetric solutions with a perfect fluid in Rastall's modified gravity theory, relating the Rastall parameter to the fluid equation‑of‑s…

Quasilocal inequalities for attractive gravity probe surface
Tetsuya Shiromizu, Keisuke Izumi, Hirotaka Yoshino +1
We discuss the local and quasilocal properties of the loosely trapped surface (LTS) and the attractive gravity probe surface (AGPS), which have been proposed to characterize the st…

Attractive gravity probe surface in Einstein-Maxwell system
Kangjae Lee, Keisuke Izumi, Tetsuya Shiromizu +2
We derive areal inequalities for five types of attractive gravity probe surfaces, which were proposed by us in order to characterize the strength of gravity in different ways inclu…
