Horndeski引力中的致密天体

Compact objects in Horndeski gravity

Hector O. Silva, Andrea Maselli, Masato Minamitsuji, Emanuele Berti

摘要:

Horndeski引力作为爱因斯坦的广义相对论的最一般的扩展具有一个标量自由度和二阶场方程。由于这些特点,Horndeski引力是一个有吸引力的现象学游乐场,以研究宇宙学和天体物理学中广义相对论的修改的后果。本文综述了在Horndeski引力下研究致密天体(黑洞和中子星)的进展。特别地,我们回顾了我们最近在慢旋转黑洞方面的工作,并给出了一些关于慢旋转中子星的新结果。

英文摘要:

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 equations. Because of these features, Horndeski gravity is an attractive phenomenological playground to investigate the consequences of modifications of general relativity in cosmology and astrophysics. We present a review of the progress made so far in the study of compact objects (black holes and neutron stars) within Horndeski gravity. In particular, we review our recent work on slowly rotating black holes and present some new results on slowly rotating neutron stars.
