Improved Models for Precession and Nutation
The modeling of nutations and precession has advanced to the point where the rms of residuals between theory and the observational estimates from the VLBI data of the past decade is only 0.16 mas in sin 0 as well as in . Such a t is provided by the MHB2000 nutation series (Mathews et al., 2000) based on geophysical theory with a few basic Earth parameters estimated by a t to nutation-precession...
متن کاملPrecession and nutation of a gyroscope
A simple treatment of the important old problem of the torque-induced rotation of a spinning symmetrical top is suggested. Our discussion is appropriate for teaching introductory mechanics and general physics to undergraduate students and is free from the difficulties of a traditional approach to the problem. The origin of nutation that accompanies forced precession is explained in detail, with...
متن کاملModeling of Nutation-Precession: Very long baseline interferometry results
Analysis of over 20 years of very long baseline interferometry data (VLBI) yields estimates of the coefficients of the nutation series with standard deviations ranging from 5 micro-arc-seconds (mas) for the terms with periods less than 400-days to 38 mas for the longest period terms. The largest deviations between the VLBI estimates of the amplitudes of terms in the nutation series and the theo...
متن کاملRelativistic spin precession in the double pulsar.
The double pulsar PSR J0737-3039A/B consists of two neutron stars in a highly relativistic orbit that displays a roughly 30-second eclipse when pulsar A passes behind pulsar B. Describing this eclipse of pulsar A as due to absorption occurring in the magnetosphere of pulsar B, we successfully used a simple geometric model to characterize the observed changing eclipse morphology and to measure t...
متن کاملThe Motion of Mars' Pole. I. Rigid Body Precession and Nutation
The total precession in longitude for a solid-core, rigid Mars model is found to be A^ = — 7!'296 + 0".01\ yr~ \ This precession includes the motion resulting from the extremely longperiod (> 10 000 yr) nutation components that result from changes in Mars' orbit with time. These same very long-period nutation components also contribute a "precession" in latitude of A£ = 0''4255 + 0!'0012 yr" ^ ...
