Gullstrand–Painlevé coordinates Derivation. The derivation of GP coordinates requires defining the following coordinate systems and understanding how Schwarzschild coordinates. A Schwarzschild observer is a far observer or a bookkeeper. He does not directly make GP coordinates. The function f Gullstrand-Painleve Coordinates First and foremost, the Gullstrand-Painlevé coordinates are not an independent solution of Einstein’s field equation, but rather an adjustment of the Schwarzschild solution to a different coordinate reference, such that the apparent coordinate singularity at [r=Rs] is avoided. Gullstrand–Painlevé coordinates are a particular set of coordinates for the Schwarzschild metric – a solution to the Einstein field equations which describes a black hole.

Gullstrand–Painlevé coordinates are a particular set of coordinates for the Schwarzschild metric – a solution to the Einstein field equations which describes a black hole. The ingoing coordinates are such that the time coordinate follows the proper time of a free-falling observer who starts from far away at zero velocity, and the spatial slices are flat.

Further, a rederivation of the work by Chen, Adler, Bjorken and Liu shows that the same results can be obtained using the Friedmann-Robertson-Walker metric, with the curvature constant set to zero, and using Gullstrand-Painlev ́e coordinates. To describe the dynamics of collapse, we use ageneralized form of the Painlevé-Gullstrand coordinates in the Schwarzschildspacetime. The time coordinate of the form is the proper time of a free-fallingobserver so that we can describe the collapsing star not only outside but alsoinside the event horizon in a single coordinate patch. For convenience, we will do this both with the Schwarzschild and GP coordinates.

2008-05-02 · Painleve-Gullstrand Coordinates for the Kerr Solution. We construct a coordinate system for the Kerr solution, based on the zero angular momentum observers dropped from infinity, which generalizes the Painleve-Gullstrand coordinate system for the Schwarzschild solution.

The Kerr metric can then be interpreted as describing space flowing 2008-12-04 · The calculations are done in Painlevé-Gullstrand (PG) coordinates that extend across apparent horizons and allow the numerical evolution to proceed until the onset of singularity formation. We generate spacetime maps of the collapse and illustrate the evolution of apparent horizons and trapping surfaces for various initial data. Painlevé-Gullstrand coordinates, a very useful tool in spherical horizon thermodynamics, fail in anti-de Sitter space and in the inner region of Reissner-Nordström. We predict this breakdown to occur in any region containing negative Misner-Sharp-Hernandez quasilocal mass because of repulsive gravity stopping the motion of PG observers, which are in radial free fall with zero initial Technically, the Gullstrand-Painlevé metric encodes not only a metric, but also a complete orthonormal tetrad, a set of four locally inertial axes at each point of the spacetime.
