    Accurate positions of candidate planetary nebulae in M 33
    We present new determinations of the positions of the planetary nebulae candidates found in Messier 33 by Magrini et al. (2000). The new coordinates have an...

    Accurate sky signal reconstruction for ground-based spectroscopy with kinetic inductance detectors
    Context. Wide-field spectrometers are needed to deal with current astrophysical challenges that require multiband observations at millimeter wavelengths. An...

    Acoustic oscillations and dynamo action in the G8 sub-giant EK Eridani
    We present further evidence of acoustic oscillations in the slowly rotating overactive G8 sub-giant EK Eri. This star was observed with the 1m Hertzsprung SONG...

    Acoustic power absorption and enhancement generated by slow and fast MHD waves. Evidence of solar cycle velocity/intensity amplitude changes consistent with the mode conversion theory
    We used long duration, high quality, unresolved (Sun-as-a star) observations collected by the ground based network BiSON and by the instruments GOLF and VIRGO...

    Acoustic-gravity wave propagation characteristics in three-dimensional radiation hydrodynamic simulations of the solar atmosphere
    There has been tremendous progress in the degree of realism of three-dimensional radiation magneto-hydrodynamic simulations of the solar atmosphere in the past...

    Active chromospheric fibril singularity: Coordinated observations from Solar Orbiter, SST, and IRIS
    Context. The fine structures of the solar chromosphere, driven by photospheric motions, play a crucial role in the dynamics of solar magnetic fields. Many such...

    Active galactic nuclei and nuclear starbursts.
    The Starburst model for radio-quiet Active Galactic Nuclei (AGN) postulates that the activity seen in most AGN is powered solely by young stars and compact...
