Schwarzschild Coordinates - Some Exact Solutions Admitting Schwarzschild Charts

Some Exact Solutions Admitting Schwarzschild Charts

Some examples of exact solutions which can be obtained in this way include:

  • the exterior region of the Schwarzschild vacuum,
  • ditto, for the Reissner-Nordström electrovacuum, which includes the previous example as a special case,
  • ditto, for the Reissner-Nordström-de Sitter electrolambdavacuum, which includes the previous example as a special case,
  • the Janis-Newman-Winacour solution (which models the exterior of a static spherically symmetric object endowed with a massless minimally coupled scalar field),
  • stellar models obtained by matching an interior region which is a static spherically symmetric perfect fluid solution across a spherical locus of vanishing pressure to an exterior region, which is locally isometric to part of the Schwarzschild vacuum region.

Famous quotes containing the words exact, solutions, admitting and/or charts:

    Since we are assured that the all-wise Creator has observed the most exact proportions of number, weight and measure in the make of all things, the most likely way therefore to get any insight into the nature of those parts of the Creation which come within our observation must in all reason be to number, weigh and measure.
    Stephen Hales (1677–1761)

    Every man is in a state of conflict, owing to his attempt to reconcile himself and his relationship with life to his conception of harmony. This conflict makes his soul a battlefield, where the forces that wish this reconciliation fight those that do not and reject the alternative solutions they offer. Works of art are attempts to fight out this conflict in the imaginative world.
    Rebecca West (1892–1983)

    It is a curious thing how poets tend to become ascetics.... Even a debauch for them is a self-flagellation. They go on the loose in cruelty against themselves, admitting that they are pandering to, and despising, the lower self.
    —D.H. (David Herbert)

    There’s one basic rule you should remember about development charts that will save you countless hours of worry.... The fact that a child passes through a particular developmental stage is always more important than the age of that child when he or she does it. In the long run, it really doesn’t matter whether you learn to walk at ten months or fifteen months—as long as you learn how to walk.
    Lawrence Kutner (20th century)
