    Distribution of MG II in the local interstellar medium towards eight cool giants
    A study of IUE spectra of eight cool G4-K0 giants shows evidence of interstellar Mg II absorption in all the stars but Delta Dra. Sharp features are detected in...
  • Publication
    Distribution of red clump stars does not support the X-shaped Galactic bulge
    Context. Claims of an X-shaped Galactic bulge were based on the assumption of red clump stars as standard candles in some lines of sight crossing the off-plane...
  • Publication
    Distribution of star formation in galactic bars as seen with Hα and stacked GALEX UV imaging
    Context. Stellar bars are known to gradually funnel gas to the central parts of disk galaxies. It remains a matter of debate why the distribution of ionized gas...
  • Publication
    Distribution of starspots on cool stars. I. Young and main sequence stars of 1Msun_.
    Sunspots are restricted to a latitude band within 30degof the solar equator. In contrast, the latitudes of spots on the surfaces of rapidly rotating cool stars...

    Distribution, sizes, and luminosity function of the HII regions in NGC 4321
    From H-alpha CCD observations taken with the 4.2-m William Herschel Telescope, a catalog of 456 H II regions of the inner zone of the spiral galaxy NGC 4321 has...
  • Publication
    Distributions, equivalent widths and metallicities of the H II regions in the spiral galaxies NGC 5457 and NGC 4395
    Using CCD observations in the narrow band filters in Hα , Hβ , [O Ii], [O Iii], [S Ii] and [S Iii] lines we have compiled a catalogue of 338 H Ii regions for...

    Diurnal atmospheric extinction over Teide Observatory (Tenerife, Canary Islands)
    Data from five continuous years (1984 to 1989) at Teide Observatory (Iza na, Tenerife, Canary Islands) obtained with a full-disc solar multichannel photometer...
  • Publication
    Diurnal photometric conditions at Teide Observatory and long-term solar irradiance variations
    Monochromatic extinction coefficients at four wavelengths have been obtained over a period of more than two years at the Observatorio del Teide (Izaña Tenerife)...
  • Publication
    Diverging UV and Hα fluxes of star-forming galaxies predicted by the IGIMF theory
    Although the stellar initial mass function (IMF) has only been directly determined in star clusters, it has been manifoldly applied on galaxy-wide scales. But...
