    NGC 1624-2: a slowly rotating, X-ray luminous Of?cp star with an extraordinarily strong magnetic field
    This paper presents a first observational investigation of the faint Of?p star NGC 1624-2, yielding important new constraints on its spectral and physical...

    NGC 2419: a large and extreme second generation in a currently undisturbed cluster
    We analyse complementary Hubble Space Telescope and Subaru data for the globular cluster NGC 2419. We make a detailed analysis of the horizontal branch (HB)...

    NGC 2579 and the carbon and oxygen abundance gradients beyond the solar circle
    We present deep echelle spectrophotometry of the Galactic H II region NGC 2579. The data have been taken with the Very Large Telescope Ultraviolet-Visual...

    NGC 6705 a young α-enhanced open cluster from OCCASO data
    Context. The stellar [α/Fe] abundance is sometimes used as a proxy for stellar age, following standard chemical evolution models for the Galaxy, as seen by...

    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, la galaxia casi invisible que desafía el modelo de materia oscura
    Un grupo de astrofísicos liderados por Mireia Montes, investigadora del Instituto de Astrofísica de Canarias (IAC), ha descubierto la galaxia más grande y...

    Nucleosíntesis y procesos moleculares en estrellas evolucionadas: de (radio) isótopos a nanoestructuras moleculares complejas.
    Las estrellas de masa baja e intermedia (M < 8 masas solares, Ms) representan la mayoría de estrellas en el Cosmos y terminan sus vidas en la Rama Asintótica de...
