Black holes and other exact spherical solutions in Quadratic Gravity

Understand

We study static, spherically symmetric vacuum solutions to Quadratic Gravity, extending considerably our previous Rapid Communication [Phys.

• Rev.
• D 98, 021502(R) (2018)] on this topic.
• Using a conformal-to-Kundt metric ansatz, we arrive at a much simpler form of the field equations in comparison with their expression in the standard spherically symmetric coordinates.
