    SBS 1150+599A: An extremely oxygen-poor planetary nebula in the Galactic halo?
    We report results of a spectrophotometric study of SBS 1150+599A and discuss the nature of this object based upon our data. Our study shows that SBS 1150+599A...

    Scaling behavior of the vertical velocity field in the solar photosphere
    We analyze, for the first time, the scaling behavior of the photospheric vertical velocity field. Our analysis is based on data collected by the Italian...

    Scaling slowly rotating asteroids with stellar occultations
    Context. As evidenced by recent survey results, the majority of asteroids are slow rotators (spin periods longer than 12 h), but lack spin and shape models...

    SDC13 infrared dark clouds: Longitudinally collapsing filaments?
    Formation of stars is now believed to be tightly linked to the dynamical evolution of interstellar filaments in which they form. In this paper we analyze the...

    Search and characterization of T-type planetary mass candidates in the σ Orionis cluster
    Context. The proper characterization of the least massive population of the young σ Orionis star cluster is required to understand the form of the cluster mass...

    Search for an extended VHE γ-ray emission from Mrk 421 and Mrk 501 with the MAGIC Telescope
    Context. Part of the very high energy γ-ray radiation coming from extragalactic sources is absorbed through the pair production process on the extragalactic...
