Abstract

In this paper, we solved the Einstein's field equation and obtained a line element for static, ellipsoidal objects characterized by the linear eccentricity (η\eta) instead of quadrupole parameter (qq). This line element recovers the Schwarzschild line element when η\eta is zero. In addition to that it also reduces to the Schwarzschild line element, if we neglect terms of the order of r2r^{-2} or higher which are present within the expressions for metric elements for large distances. Furthermore, as the ellipsoidal character of the derived line element is maintained by the linear eccentricity (η\eta), which is an easily measurable parameter, this line element could be more suitable for various analytical as well as observational studies.
