Over the past two decades, helioseismology has revolutionized our understanding of the interior structure and dynamics of the Sun. Asteroseismology will soon...

Context. Stellar occultation is a powerful technique that allows the determination of some physical parameters of the occulting object. The result depends on...

Context. Transiting sub-Neptune-type planets, with radii approximately between 2 and 4 R ⊕, are of particular interest as their study allows us to gain insight...

We present results from 30 nights of observations of the open cluster NGC 7789 with the Wide Field Camera on the Isaac Newton Telescope, La Palma. From ~900...

Asteroseismology with the Kepler space telescope is providing not only an improved characterization of exoplanets and their host stars, but also a new window on...

Filaments are omnipresent features in the solar atmosphere. Their location, properties, and time evolution can provide important information about changes in...

We study the frequency dependence of the frequency shifts of the low-degree p modes measured in the F5V star HD 49933, by analyzing the second run of...

In non-equilibrium plasma spectroscopy it may happen to have to deal with ensembles of particles, whose velocity distribution is not the equilibrium (i.e...

We investigate the physical state of H I absorbing gas at low redshift (z = 0.25) using a subset of cosmological, hydrodynamic simulations from the...
