Radial oscillations of neutron stars in Starobinsky gravity and its Gauss-Bonnet extension
Ziyi Li, Zhong-Xi Yu, Zhe Luo +2
Starobinsky gravity, as one of the simplest and best-behaved higher-curvature gravity theories, has been extensively studied in the context of neutron stars over the past few decad…

Neutron stars in Gauss-Bonnet extended Starobinsky gravity
Zhonghai Liu, Ziyi Li, Liang Liang +2
Recently, a class of Gauss-Bonnet extended Starobinsky gravity was proposed, allowing black holes to carry ghost-free massive scalar hair for the first time without requiring addit…
