We have studied the statistical properties of the energy of individual acoustic modes, extracted from 310 days of GOLF data near the solar minimum. The...
Are solar chromospheric fibrils tracing the magnetic field?
Fibrils are thin elongated features visible in the solar chromosphere in and around magnetized regions. Because of their visual appearance, they have been...
Now almost 70 years since its introduction, the effective or half-light radius has become a very popular choice for characterising galaxy size. However, the...
Aims: The knowledge of physical conditions in young radio sources is important for defining the framework of models describing radio source evolution. We...
Aims: We present a new upgraded version of ARES. The new version includes a series of interesting new features such as automatic radial velocity correction, a...
Arm and interarm abundance gradients in CALIFA spiral galaxies
Spiral arms are the most singular features in disc galaxies. These structures can exhibit different patterns, namely grand design and flocculent arms, with...
ARRAKIS: atlas of resonance rings as known in the S4G
Context. Resonance rings and pseudorings (here collectively called rings) are thought to be related to the gathering of material near dynamical resonances...
Assessing the accuracy of star formation rate measurements by direct star count in molecular clouds
Star formation estimates based on the counting of young stellar objects (YSOs) are commonly carried out for nearby star-forming regions in the Galaxy, and in...
Asteroid reflectance spectra from Gaia DR3: Near-UV in primitive asteroids
Context. In the context of charge-coupled devices (CCDs), the ultraviolet (UV) region has mostly remained unexplored after the 1990s. Gaia DR3 offers the...
