  1. 1. Matter-streams as sources of the Kerr metric

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Julian Boy; [2022]
    Keywords : General Relativity; Black holes; Physics; Kerr metric; Physics and Astronomy;

    Abstract : An introduction to the thin-shell formalism and distributional approach to General Relativity is provided. The formalism is utilized to investigate possible distributions of matter that can act as a source to the Kerr metric. READ MORE

  3. 2. Spherically Symmetric Gravitational Collapse

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Lucas Bring; [2021]
    Keywords : gravitational collapse; gravitation; general relativity; black hole; Schwarzschild coordinates; Gullstrand-Painleve coordinates; Friedmann-Robertson-Walker metric; finite-time collapse; Physics and Astronomy;

    Abstract : This thesis presents a derivation of the equation of motion of particles in a dust star, as it undergoes collapse. This is done by finding exact solutions to the Einstein field equations. We follow the original work by Oppenheimer and Snyder, starting from the general spherically symmetric metric in comoving coordinates. READ MORE

  4. 3. Derivation and stability determination of black hole metrics

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Emma Svensson; [2018]
    Keywords : black holes; relativity; general relativity; kerr metric; schwarzschild metric; derivation; stability; Physics and Astronomy;

    Abstract : The Schwarzschild metric and the Kerr metric describe the gravitational fields around static and rotating black holes, respectively. Here, we derive the Kerr metric in a simpler way than how it was derived originally and determine the stability of the Schwarzschild metric. READ MORE

  5. 4. The Hawking mass for ellipsoidal 2-surfaces in Minkowski and Schwarzschild spacetimes

    University essay from Matematiska institutionen

    Author : Daniel Hansevi; [2008]
    Keywords : Hawking mass; Quasi-local mass; General relativity; Ellipsoidal surface;

    Abstract : In general relativity, the nature of mass is non-local. However, an appropriate def-inition of mass at a quasi-local level could give a more detailed characterization ofthe gravitational field around massive bodies. Several attempts have been made tofind such a definition. One of the candidates is the Hawking mass. READ MORE
