After 8 months of nearly continuous measurements the GOLF instrument, aboard SOHO, has detected acoustic mode frequencies of more than 100 modes, extending from...

We present a numerical code that solves the forward and inverse problem of the polarized radiative transfer equation in geometrical scale under the Zeeman...

In this paper, we study the nuclear obscuration of galaxies hosting low ionization narrow emission regions (LINERs) based on their X-ray and optical emission...

With data from Pantheon, we have at our disposal a sample of more than a 1000 supernovae Ia covering a wide range of redshifts with good precision. Here, we...

The new generation of solar instruments provides better spectral, spatial, and temporal resolution for a better understanding of the physical processes that...

Context. The nature of ultra-luminous X-ray (ULX) sources is still a matter of debate. Studies of their counterparts in other spectral ranges will help to...

Precise space-based photometry from the Transiting Exoplanet Survey Satellite results in a huge number of exoplanetary candidates. However, the masses of these...

Colour-magnitude diagrams in the Washington system are presented for the first time for five star clusters projected on to the outer region of the Small...

Context. We present the analysis of emission lines in high-resolution optical spectra of the planet-host star Proxima Centauri (Proxima) classified as a M5.5V...
