    A SART-Based Iterative Inversion Methodology to Infer the Solar Rotation Rate from Global Helioseismic Data
    We present a new iterative rotation inversion technique based on the Simultaneous Algebraic Reconstruction Technique developed for image reconstruction. We...

    An attempt to compare the differential rotation of the Ca/plus/-network with that of the photospheric plasma
    Results of almost simultaneous observations of the differential rotation of the Ca(plus) chromosphere and the photospheric plasma are reported. The observations...

    Differential rotation and meridional motions of sunspots from 1874 to 1902
    Position data of sunspot groups from the period 1874-1902 are used to investigate the differential rotation of the Sun and the meridional motions of the...

    Differential rotation and the SPOT zones
    Doppler measurements, using the Capri magnetograph, of the latitudinal fine structure of the solar differential rotation have been carried out. The positions of...

    Differential rotation of sunspot groups in the period from 1874 through 1976 and changes of the rotation velocity within the solar cycle
    An effort is made to determine the differential rotation of the sun on the basis of the complete sample (1874-1976) of the Greenwich Photoheliographic Results...

    Effect of atmospheric extinction on solar radial velocity measurements
    Effects of differential extinction across the Earth's atmosphere on astronomical photometry are reviewed. Under the same circumstances when a rotating extended...

    Large-scale solar motions as determined by Doppler shift measurements using a linear photodiode array
    Doppler shifts of the solar Fe line 630.15 nm relative to the terrestrial O2 line 630.2 nm were determined at many positions on the solar disk to investigate...

    New information about solar rotation
    It is pointed out that the phenomenon of solar rotation is known since the introduction of the telescope into astronomy by Galilei in 1610. Regular measurements...
