PublicationA stellar occultation by the transneptunian object (50000) Quaoar observed by CHEOPS
Context. Stellar occultation is a powerful technique that allows the determination of some physical parameters of the occulting object. The result depends on...

PublicationA sub-Neptune and a non-transiting Neptune-mass companion unveiled by ESPRESSO around the bright late-F dwarf HD 5278 (TOI-130)
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...

PublicationA survey for planetary transits in the field of NGC 7789
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...

PublicationA Uniform Asteroseismic Analysis of 22 Solar-type Stars Observed by Kepler
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...

PublicationAbout the p-mode frequency shifts in HD 49933
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...

PublicationAbsorption and emission coefficients of non-equilibrium plasmas
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...

PublicationAbsorption signatures of warm-hot gas at low redshift: broad H I Lyα absorbers
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...

PublicationAbsorption signatures of warm-hot gas at low redshift: O VI
We investigate the origin and physical properties of O VI absorbers at low redshift (z= 0.25) using a subset of cosmological, hydrodynamical simulations from...
