报告摘要： 

The Taub-NUT black hole solution was discovered in the middle of last century. The thermodynamics of this solution is still controversial, particularly, the definition and physical interpretation of its mass and NUT charge. We have developed procedures to calculate all the thermodynamic quantities and we find that the results are consistent with the first law (Wald formalism), the Euclidean action and the Smarr relation. The modification of a cubic curvature invariant to the thermodynamics of Taub-NUT spacetimes was also studied to the first order. We then constructed new Taub-NUT black holes with hair in higher derivative gravity theories.
