    Nitrogen abundances of the Be-type stars in 30 Doradus
    A sub-set of the 67 Be-type stars observed in 30 Doradus during the VLT-FLAMES Tarantula Survey (VFTS) campaign have been analysed to estimate atmospheric...

    No temperature fluctuations in the giant H II region H 1013
    While collisionally excited lines in H ii regions allow one to easily probe the chemical composition of the interstellar medium in galaxies, the possible...

    Non-synchronous rotations in massive binary systems. HD 93343 revisited
    Context. Most massive stars are in binary or multiple systems. Several massive stars have been detected as double-lined spectroscopic binaries and among these...

    Nonaxisymmetric models of galaxy velocity maps
    Galaxy velocity mapsoften show the typical pattern of a rotating disk, consistent with the dynamical model where emitters rotate in circular orbits around the...

    Nube, the almost invisible galaxy which challenges the dark matter model
    A group of astrophysicists led by Mireia Montes, a researcher at the Instituto de Astrofísica de Canarias (IAC), has discovered the largest and most diffuse...

    Nucleosynthesis and molecular processes in evolved stars: from (radio) isotopes to complex molecular nanostructures
    Low- to intermediate-mass (M < 8 solar masses, Ms) stars represent the majority of stars in the Cosmos. They finish their lives on the Asymptotic Giant Branch...

    Nucleosynthesis and molecular processes in the late stages of Stellar Evolution
    Low- to intermediate-mass (M < 8 solar masses, Ms) stars represent the majority of stars in the Cosmos. They finish their lives on the Asymptotic Giant Branch...

    Observational constraints to boxy/peanut bulge formation time
    Boxy/peanut bulges are considered to be part of the same stellar structure as bars and both could be linked through the buckling instability. The Milky Way is...

    Observational Evidence for a Correlation Between Macroturbulent Broadening and Line-profile Variations in OB Supergiants
    The spectra of O and B supergiants (Sgs) are known to be affected by a significant form of extra line broadening (usually referred to as macroturbulence) in...
