Estimates of relativistic and interplanetary magnetic effects on precession and nutation
Abstract
In this paper, we discuss the relativistic effect on precession and nutation. The geodesic precession and nutation are the largest caused by the relativistic effect. Its annual term comes to 1.53 x 10 exp -4 arcsec, about two orders larger than the smallest term (5 x 10 exp -6 arcsec) in Kinoshita-Souchay's (1990) nutation series. In addition, the semiannual term (2 x 10 exp -6 arcsec) is compatible with their smallest one. Whether the geodesic precession is explicitly involved when Lieske's (1967) precession coefficients are calculated may result in 9-unit's difference.
