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: 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...
Assessing spectra and thermal inversions due to TiO in hot Jupiter atmospheres
Recent detections of thermal inversions in the dayside atmospheres of some hot Jupiters are motivating new avenues to understand the interplay between their...
Assessing the Behavior of Modern Solar Magnetographs and Spectropolarimeters
The design and later use of modern spectropolarimeters and magnetographs require a number of tolerance specifications that allow the developers to build the...
Asteroid Lightcurves from the MOA-II Survey: a pilot study
The Microlensing Observations in Astrophysics (MOA-II) survey has performed high cadence, wide field observations of the Galactic Bulge from New Zealand since...
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...
Asteroids' reflectance from Gaia DR3: Artificial reddening at near-UV wavelengths
Context. Observational and instrumental difficulties observing small bodies below 0.5 μm make this wavelength range poorly studied compared with the visible and...
Asteroseismic masses of four evolved planet-hosting stars using SONG and TESS: resolving the retired A-star mass controversy
The study of planet occurrence as a function of stellar mass is important for a better understanding of planet formation. Estimating stellar mass, especially in...
