From an analysis of the stars remaining in central regions of the Galaxy after subtracting those belonging to the disc and the bulge, we deduce that the inner...
An explanation for the Stokes V asymmetry in solar faculae
The asymmetry in the Stokes V profile observed in solar faculae can be explained by assuming that the magnetic field increases with height while downflow speed...
An extended low-density atmosphere around the Jupiter-sized planet WASP-193 b
Gas giants transiting bright nearby stars provide crucial insights into planetary system formation and evolution mechanisms. Most of these planets show certain...
An Extended Lyα Outflow from a Radio Galaxy at z = 3.7?
Spatially resolved observations of active galactic nuclei (AGN) host galaxies undergoing feedback processes are one of the most relevant avenues through which...
An extension of Herschel's method for dense and extensive catalogues. Application to the determination of solar motion
We present a way of handling and interpreting stellar proper motions, in which the idea of substituting them by great circles, proposed by Herschel in 1783...
An extension of the MILES library with derived T<SUB>eff</SUB>, log g, [Fe/H], and [α/Fe]
Extragalactic astronomy and stellar astrophysics are intrinsically related. In fact, the determination of important galaxy properties such as stellar masses...
An extensive spectroscopic time series of three Wolf-Rayet stars - I. The lifetime of large-scale structures in the wind of WR 134
During the summer of 2013, a 4-month spectroscopic campaign took place to observe the variabilities in three Wolf-Rayet stars. The spectroscopic data have been...
An extensive spectroscopic time series of three Wolf-Rayet stars - II. A search for wind asymmetries in the dust-forming WC7 binary WR137
We present the results of a 4-month, spectroscopic campaign of the Wolf-Rayet dust-making binary, WR137. We detect only small-amplitude random variability in...
An extreme blue nugget, UV-bright starburst at z = 3.613 with 90 per cent of Lyman continuum photon escape
We present the discovery and analysis of J1316+2614 at z = 3.6130, a UV-bright star-forming galaxy (M UV ≃ -24.7) with large escape of Lyman continuum (LyC)...
