    Deep survey of millimeter radio recombination lines toward the planetary nebulae IC 418 and NGC 7027
    Context. The circumstellar environments of planetary nebulae (PNe) are remarkably chemically rich astrophysical laboratories, proving useful for studies of the...

    Deep view of the intracluster light in the Coma cluster of galaxies
    The detection and study of the intracluster light (ICL) in rich clusters of galaxies has been a longstanding challenge and key focus. Using the lowest-surface...

    Deep wide-field imaging down to the oldest main sequence turn-offs in the Sculptor dwarf spheroidal galaxy
    We present wide-field photometry of resolved stars in the nearby Sculptor dwarf spheroidal galaxy using CTIO/MOSAIC, going down to the oldest main sequence turn...

    DeepVel: Deep learning for the estimation of horizontal velocities at the solar surface
    Many phenomena taking place in the solar photosphere are controlled by plasma motions. Although the line-of-sight component of the velocity can be estimated...

    delta Scuti stars in Praesepe I. The STACC 1998 campaign - the photometry
    We present the results of the multisite differential CCD photometry for the two delta Scuti stars, BN and BV Cnc, in the open cluster Praesepe. The main...

    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 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...

    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...
