WebSummary. In this chapter, we describe what is widely known as the Taub–NUT solution. This was first discovered by Taub (1951), but expressed in a coordinate system which only … WebJul 16, 2024 · We find a new class of exact solutions in the Einstein–Maxwell theory by employing the Ernst magnetization process to the Kerr–Newman–Taub-NUT spacetimes. We study the solutions and find that they are regular everywhere. We also find the quasilocal conserved quantities for the spacetimes, the corresponding Smarr formula and the first …

WebThe Taub-NUT metrics were discovered by Taub [1] and later extendedby Newmann-Unti-Tamburino [2]. They arecomplete Ricci-flat self-dual metrics on R4 and Hawking showed that they are non-trivial examples of the gravitational instantons [3]. Taub-NUT space has attracted a significant interest Webthe Taub-NUT solution and so the NUT parameter is sometimes referred to as the magnetic mass [22]. In general, however, the Taub-NUT solution is a dyon with both electric and magnetic mass.
WebSep 25, 1978 · One of the first examples given of a gravitational instanton was the self-dual Taub--NUT solution [ 1 ] . It is asymptotically flat with a central "nut", in the language of ref. [6]. This note will show that there is another Taub-NUT instanton which is also asymptotically flat but which has an horizon or "bolt" in the middle. WebNov 3, 2003 · The Kerr‐Taub‐NUT metric is a local analytic solution of the vacuum Einstein‐Maxwell equations. When the metric is expressed in Schwarzschild‐like coordinates, two types of coordinate singularity are present. One occurs at certain values of the ``radial'' coordinate where grr becomes infinite and corresponds to bifurcate Killing ...
