From inversion of a time series of slit spectra, observed in a quiet region of the solar photosphere, averaged models of a granular cell have been obtained...
Moderately misaligned orbit of the warm sub-Saturn HD 332231 b
Measurements of exoplanetary orbital obliquity angles for different classes of planets are an essential tool in testing various planet formation theories...
Molar extinction coefficient of fullerenes and related hydrogenated derivatives ``fulleranes''
Fullerenes, the carbon molecules with 60 and 70 atoms, were recently detected in a series of planetary nebulae, in protoplanetary nebulae and in other...
More fundamental than the fundamental metallicity relation. The effect of the stellar metallicity on the gas-phase mass-metallicity and gravitational potential-metallicity relations
Context One of the most fundamental scaling relations in galaxies is observed between metallicity and stellar mass - the mass-metallicity relation (MZR) -...
Morphology and spectral properties of the DART impact ejecta with VLT/MUSE
Context. On September 26, 2022, the NASA DART mission impacted the asteroid Dimorphos, the smaller component of the Didymos binary asteroid system. This...
Multi-colour light variation of AGB stars observed with ISO
New visual light curves and infrared multi-epoch photometry are presented for a sample of AGB-stars spectroscopically observed with ISO. While the ISO work is...
Multi-conjugate adaptive optics images of the Trapezium cluster
Context: Multi-conjugate adaptive optics (MCAO) combine the advantages of both standard adaptive optics, which provide high contrast and high spatial resolution...
Multi-fibre optical spectroscopy of low-mass stars and brown dwarfs in Upper Scorpius
Context. Knowledge of the mass function in open clusters constitutes one way to critically examine the formation mechanisms proposed to explain the existence of...
Multi-instrument measurement campaign at Paranal in 2007. Characterization of the outer scale and the seeing of the surface layer
Aims: Within the framework of site qualification for the future European large telescope E-ELT, a campaign of measurements was carried out for ten nights in...
