    A near-infrared survey for new low-mass members in α Per
    We present a near-infrared (K'-band) survey of 0.7 square degree area in the α Persei open cluster (age = 90 Myr, distance = 182 pc) carried out with the Omega...

    A new and Homogeneous metallicity scale for Galactic classical Cepheids. II. Abundance of iron and α elements
    Context. Classical Cepheids are the most popular distance indicators and tracers of young stellar populations. The key advantage is that they are bright and...

    A new code for automatic determination of equivalent widths: Automatic Routine for line Equivalent widths in stellar Spectra (ARES)
    Aims:We present a new automatic code (ARES) for determining equivalent widths of the absorption lines present in stellar spectra. We also describe its use for...

    A new discovery space opened by eROSITA. Ionised AGN outflows from X-ray selected samples
    Context. In the context of an evolutionary model, the outflow phase of an active galactic nucleus (AGN) occurs at the peak of its activity, once the central...

    A new dynamical modeling of the WASP-47 system with CHEOPS observations
    Among the hundreds of known hot Jupiters (HJs), only five have been found to have companions on short-period orbits. Within this rare class of multiple...

    A new free-floating planet in the Upper Scorpius association
    We report on a deep photometric survey covering an area of 1.17 deg2 in the young Upper Scorpius stellar association using VIMOS Iz and UKIDSS ZJHK data that...

    A new implementation of the infrared flux method using the 2MASS catalogue
    Context: The effective temperature scale of FGK stars, especially at the lowest metallicities remains a major problem in the chemical abundance analysis of...

    A new L5 brown dwarf member of the Hyades cluster with chromospheric activity
    Aims: Our aim is to identify brown dwarf members of the nearby Hyades open star cluster to determine the photometric and spectroscopic properties of brown...

    A new method for age-dating the formation of bars in disc galaxies. The TIMER view on NGC1433's old bar and the inside-out growth of its nuclear disc
    The epoch in which galactic discs settle is a major benchmark for testing models of galaxy formation and evolution but remains largely unknown. Once discs...
