Study Notes
C.V. Vishveshwara's Contributions
- Made significant contributions to black hole physics and cosmology in general relativity
- Proved the stability of axisymmetric perturbations of Kerr black holes
- One of the first to analyze the structure of black holes employing spacetime symmetries
- Demonstrated the existence of ergospheres in black holes
Black Hole Physics
- Discovered that black holes with hair (scalar hair) are a main target of observation using gravitational wave detectors
- Investigated the physics of black hole collisions in later years, which had hardly been explored
Plasma Physics
- The Debye sheath is a region near the surface of a material where the plasma is separated from the material
- The thickness of the Debye sheath is determined by the Debye length
- The surface of a material becomes negatively charged relative to the bulk plasma at the interface due to the difference in mobility between ions and electrons
- The transition between two plasma regions with different characteristics is known as the plasma boundary
- The condition that signals an equilibrium in the Debye sheath is when the electric field and the density gradient are balanced
