Abstract: (Elsevier)
Stationary, spherically symmetric, asymptotically flat solutions of the Kaluza-Klein theory corresponding to regular black holes in four dimensions are discussed and classified. The thermodynamic properties of the holes are discussed and Smarr-type relations obtained. The thermal evaporation of the holes is considered. In the magnetically neutral case discharging of holes (by pyrgon emission) is only significant for solutions close to the extreme configuration Q 2 = 4κ 2 M 2 , 4πΣ = √3κ M . For holes with nonvanishing magnetic charge an evolution towards the extreme configuration corresponding to the Gross-Perry-Sorkin monopole is expected. The gyromagnetic ratio of rotating black holes is briefly discussed and compared to that of pyrgons and massive 5-dimensional fields.- black hole
