A Circular Statistical Method for Extracting Rotation Measures
Polarization—methods galaxies magnetic fields
font style='font-size:12px;'>
2009/5/19
We propose a new method for the extraction of Rotation Measures
from spectral polarization data. The method is based on maximum
likelihood analysis and takes into account the circular nature of the ...
An Apparent Descriptive Method for Judging the Synchronization of Rotation of Binary Stars
Binary stars synchronization of rotation
font style='font-size:12px;'>
2009/5/14
The problem of the synchronous rotation of binary stars is
judged by using a synchronous parameter Q introduced in an apparent
descriptive method. The synchronous parameter Q is defined as the ratio...

This paper reviews the precision of the measurements of the Earth
rotation fluctuations realized during the last decades; particularly the observations
performed during the last ten years allow to c...
SOME FRESH INDICATIONS OF THE SOLAR ORIGIN OF 4-6-YEAR OSCILLATION OF THE EARTH'S ROTATION PARAMETERS

The variations of universal times difference UT1-TAI and Earth’s
rotation instantaneous pˆole coordinates (X,Y) are studied in the frequency range
of 3 - 8 yr−1 as a function of the solar...
INTERACTION BETWEEN VARIABLE SOLAR UV RADIATION AND TROPOSPHERIC CIRCULATIONS AS A POSSIBLE CAUSE OF FIVE YEAR OSCILLATION IN EARTH ROTATION
VARIABLE SOLAR UV RADIATION TROPOSPHERIC CIRCULATIONS EARTH ROTATION
font style='font-size:12px;'>
2009/3/16
It is shown that Five Year Oscillation in Earth rotation is possibly
caused by variable solar UV radiation and a corresponding perturbation mechanism
is suggested.
