Spherically symmetric solutions with any cosmological constant in the Einstein-Weyl gravity
Original language description
In our contribution we present spherically symmetric solutions in four dimensions tothe Einstein-Weyl (and also general quadratic) gravity admitting arbitrary value of thecosmological constant. The main attention is paid to the black hole spacetimes represent-ing one parameter extension of the well-known Schwarzschild-(anti-)de Sitter geometry ofEinstein’s general relativity. This additional parameter corresponds to the non-vanishingvalue of the Bach tensor at the black hole horizon. Our work thus generalises recent pa-per by L ̈u et al. (Phys. Rev. Lett. 114 (2015) 171) to any value of the cosmologicalconstant. Moreover, using more convenient metric ansatz, the field equations form anautonomous system and their solution is explicitly obtained in an exact form of powerseries. The physical interpretation of these geometries is also discussed, namely we inves-tigate specific tidal effects on free test particles or their basic thermodynamic properties.
