Accurate p-mode measurements of the G0V metal-rich CoRoT target HD 52265
Context. The star HD 52265 is a G0V metal-rich exoplanet-host star observed in the seismology field of the CoRoT space telescope from November 2008 to March...
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...
Active region fine structure observed at 0.08 arcsec resolution
Context. The various mechanisms of magneto-convective energy transport determine the structure of sunspots and active regions. Aims: We characterise the...
Activity from the Be/X-ray binary system V0332+53 during its intermediate-luminosity outburst in 2008
Aims: We present a study of the Be/X-ray binary system V 0332+53 with the main goal of characterizing its behaviour mainly during the intermediate-luminosity X...
Activity of the Jupiter co-orbital comet P/2019 LD<SUB>2</SUB> (ATLAS) observed with OSIRIS at the 10.4 m GTC
Context. The existence of comets with heliocentric orbital periods close to that of Jupiter (i.e., co-orbitals) has been known for some time. Comet 295P/LINEAR...
