    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...

    Diffuse interstellar bands in fullerene planetary nebulae: the fullerenes - diffuse interstellar bands connection
    We present high-resolution (R ~ 15 000) VLT/UVES optical spectra of two planetary nebulae (PNe; Tc 1 and M 1-20) where C60 (and C70) fullerenes have already...

    Diffuse interstellar bands λ5780 and λ5797 in the Antennae Galaxy as seen by MUSE
    Context. Diffuse interstellar bands (DIBs) are faint spectral absorption features of unknown origin. Research on DIBs beyond the Local Group is very limited and...

    Diffuse light in Hickson compact groups: the dynamically young system HCG 44
    Context: .Compact groups are associations of a few galaxies in which the environment plays an important role in galaxy evolution. The low group velocity...

    Diffusion of Solar Magnetic Elements up to Supergranular Spatial and Temporal Scales
    The study of spatial and temporal scales on which small magnetic structures (magnetic elements) are organized in the quiet Sun may be approached by determining...

    Digging deeper into NGC 6868 II: ionized gas and excitation mechanism
    We studied the ionized gas in the inner region ( $\sim$ $680\times 470$ pc 2) of the galaxy NGC 6868 using Gemini/GMOS (Gemini Multi-Object Spectrograph)...

    Digging into the surface of the icy dwarf planet Eris
    We describe optical spectroscopic observations of the icy dwarf planet Eris with the 6.5-m MMT telescope and the Red Channel Spectrograph. We report a...
