    The Arches cluster revisited. II. A massive eclipsing spectroscopic binary in the Arches cluster
    We have carried out a spectroscopic variability survey of some of the most massive stars in the Arches cluster, using K-band observations obtained with SINFONI...

    The Arches cluster revisited. III. An addendum to the stellar census
    The Arches is one of the youngest, densest and most massive clusters in the Galaxy. As such it provides a unique insight into the lifecycle of the most massive...

    The atmosphere and architecture of WASP-189 b probed by its CHEOPS phase curve
    Context. Gas giants orbiting close to hot and massive early-type stars can reach dayside temperatures that are comparable to those of the coldest stars. These...

    The atmosphere of HD 209458b seen with ESPRESSO. No detectable planetary absorptions at high resolution
    We observed two transits of the iconic gas giant HD 209458b between 380 and 780 nm, using the high-resolution ESPRESSO spectrograph. The derived planetary...

    The atmospheric composition of the ultra-hot Jupiter WASP-178 b observed with ESPRESSO
    Context. Ultra-hot Jupiters (UHJ) have emerged as ideal testbeds for new techniques for studying exoplanet atmospheres. Only a limited number of them are...

    The atmospheric parameters and spectral interpolator for the MILES stars
    Context. Empirical libraries of stellar spectra are used to classify stars and synthetize stellar populations. MILES is a medium spectral-resolution library in...

    The atmospheric variations of the peculiar B[e] star HD 45677 (FS Canis Majoris).
    We have studied spectra of the peculiar B[e] star HD 45677. Examination of the Balmer wings enabled us to determine a value of logg=3.9 indicating a possibly...

    The B0.5 IVe CoRoT target HD 49330. II. Spectroscopic ground-based observations
    Context: We present spectroscopic ground-based observations of the early Be star HD 49330 obtained simultaneously with the CoRoT-LRA1 run just before the burst...

    The BaSTI Stellar Evolution Database: models for extremely metal-poor and super-metal-rich stellar populations
    We present an extension of the BaSTI (Bag of Stellar Tracks and Isochrones) stellar evolution database to extremely metal-poor (Z = 10-5) and super-metal-rich...
