    Newly formed downflow lanes in exploding granules in the solar photosphere
    Context. Exploding granules have drawn renewed interest because of their interaction with the magnetic field (either emerging or already present). Especially...

    NGC 4526 gas, high velocity clouds, and Galactic halo gas: the interstellar medium towards SN 1994D.
    We present spectroscopic observations of supernova 1994D in NGC 4526, an S0_3_ galaxy in the Virgo cluster 15Mpc distant. The datasets consist of the...

    NGC 4672: A new case of an early-type disk galaxy with an orthogonally decoupled core
    We report the case of the early-type disk galaxy NGC 4672 as a new example of a galaxy characterized by the orthogonal geometrical decoupling between bulge and...

    NGC 6240: A triple nucleus system in the advanced or final state of merging
    Aims: NGC 6240 is a well-studied nearby galaxy system in the process of merging. Based on optical, X-ray, and radio observations, it is thought to harbor two...

    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...

    NICS-TNG infrared spectroscopy of NGC 1068: The first extragalactic measurement of [P II] and a new tool to constrain the origin of [Fe II] line emission in galaxies
    We report 0.9-1.4 mu m spectroscopic observations of NGC 1068 collected during the commissioning phase of the near infrared camera spectrometer (NICS) of the...

    Nitrogen abundances in planet-harbouring stars
    We present a detailed spectroscopic analysis of nitrogen abundances in 91 solar-type stars, 66 with and 25 without known planetary mass companions. All...
