Black holes with regular scalar hair in Brans-Dicke gravity via the Herglotz variational principle
Marek Wazny
Brans-Dicke theory is reformulated within the Herglotz variational principle (HVP), and an exact black hole solution with scalar hair is obtained for and vanishing poten…
Herglotz-type gravity
Marek Wazny, Lehel Csillag, Miguel A. S. Pinto +1
The non-conservation of the energy-momentum tensor in gravity can be interpreted as an effective manifestation of dissipation. Motivated by this, we propose a new formulat…
Conservative cosmology in scalar-tensor Herglotz gravity
Marek Wazny
The scalar-tensor representation of gravity is extended to incorporate the Herglotz variational principle. The field equations are derived in both the geometric and scalar…
Hot Jupiters are asynchronous rotators
Marek Wazny, Kristen Menou
Hot Jupiters are typically assumed to be synchronously rotating, from tidal locking. Their thermally-driven atmospheric winds experience Lorentz drag on the planetary magnetic fiel…
