    Density discrepancy between transit-timing variations and radial velocity: Insights from the host star composition
    Context. The determination of planetary densities from the masses derived with the radial velocity (RV) and transit-timing variation (TTV) methods reveals...

    Density distribution of the cosmological matter field
    The one-point probability distribution function (PDF) of the matter density field in the universe is a fundamental property that plays an essential role in...

    Density studies on giant extragalactic H II regions
    We report the results of a systematic study on the spatial variation of the electron density in a selected group of bright giant H II complexes in the galaxies...

    Density waves and star formation in grand-design spirals
    Context. H II regions in the arms of spiral galaxies are indicators of recent star-forming processes. They may have been caused by the passage of the density...

    Density weighted angular redshift fluctuations: a new cosmological observable
    We propose the use of angular fluctuations in the galaxy redshift field as a new way to extract cosmological information in the Universe. This new probe $\delta...

    Density, not radius, separates rocky and water-rich small planets orbiting M dwarf stars
    Exoplanets smaller than Neptune are common around red dwarf stars (M dwarfs), with those that transit their host star constituting the bulk of known temperate...

    Departure from the constant-period ephemeris for the transiting exoplanet WASP-12
    Aims: Most hot Jupiters are expected to spiral in toward their host stars because the angular momentum of the orbital motion is transferred to the stellar spin...

    Dependence of sunspot photospheric waves on the depth of the source of solar p-modes
    Photospheric waves in sunspots moving radially outward at speeds faster than the characteristic wave velocities have been recently detected. It has been...

    Dependence of the photospheric vertical flow characteristics on the granule dimension
    The first high spectral resolution and white-light images obtained at the THEMIS telescope with the Italian Panoramic Monochromator (IPM), are analyzed to study...
