The concentration ofmass more than the solar one within about 20km, requires general relativisticdescription, with the equation of state governing the physics still being largelyunknown. The observational analogue of neutron stars are believed to be pul-sars, which are found to rotate with periods down to» 1msec. Rapidly rotatingcompact objects like these, are extremely interesting for physics, since theyprovide conditions that could hardly be produced in a laboratory on earth.Electromagnetic radiation is, so far, the only way to observe and study theseobjects, with gravitational waves being the promising new window that generaltheoryofrelativityhaspredictedtoopeninthefuture. Therecenttechnologicalachievements in laser interferometry are just enabling detection of such wavesfrom our galaxy.
