A Relativistic Study for the Solar Limb Effect |
Abstract _ |
Solar Limb Effect is an observational phenomena connected to the solar gravitational red-shift. It is the variation of the magnitude of the gravitational red-shift from the center to the limb of the solar disc[1]. An attempt, for interpreting this phenomena using a general relativistic red-shift formula, is given . This formula takes into account the effect of the gravitational field, the effect of the solar rotation, the effect of the inclination of the line of sight and the motion of the observe. In this study the gravitational field of the Sun is assumed to be given by Lense-Thirring field and the Earth is assumed to move in an elliptic orbit. Comparison with previous relativistic study [2] and with observation is given. [1] Adam, M.G. (1979) Mon. Not. R. astr. Soc. , 188, 819 [2] Mikhail F.I. Wanas M.I. and Morcos A.B. (2002) Astrophys.
