The solar rotation rate at latitudes 0 deg, 15 deg and 30 deg has been inferred by averaging the results of 120 regions of 15 degx15 deg, which have been...

The site survey for the Advanced Technology Solar Telescope concluded recently after more than 2 years of data gathering and analysis. Six locations, including...

We estimated the scale-length of the thin disc with the J and W1 magnitudes of the most probable red clump stars in the Galactic plane, - 0°.5 ⩽ b ⩽ +0°.5, in...

An overall view of the solar surface is presented with emphasis on the study of low 1 value oscillations. Line of sight velocity measurements of the whole solar...

Various aspects of the magnetism of the quiet sun are reviewed. The suggestion that a small scale dynamo acting at granular scales generates what we call the...

Context. Surges are cool and dense ejections typically observed in chromospheric lines and closely related to other solar phenomena such as UV bursts or coronal...

The importance of the quiet-Sun magnetism is that it is always there to a greater or lesser extent, being a constant provider of energy, independently of the...

Binary stars in which oscillations can be studied in either or both components can provide powerful constraints on our understanding of stellar physics. The...

We present the results of the asteroseismic analysis of the red-giant star KIC 4351319 (TYC 3124-914-1), observed for 30 d in short-cadence mode with the Kepler...
