    New bright optical spectrophotometric standards: A-type stars from the STIS Next Generation Spectral Library
    Exoplanets have sparked interest in extremely high signal-to-noise ratio spectroscopic observations of very bright stars, in a regime where flux calibrators, in...

    New Brown Dwarfs in the Pleiades Cluster
    We present intermediate- and low-resolution optical spectroscopy (650-915 nm) of seven faint, very red objects ( 20>I>=17.8 , I-Z>= 0.5) discovered in a CCD...

    New brown dwarfs in Upper Sco using UKIDSS Galactic Cluster Survey science verification data
    We present first results from a deep (J = 18.7), wide-field (6.5deg2) infrared (ZY JHK) survey in the Upper Sco association conducted within the science...

    New candidate planetary nebulae in M 81
    A 34'x34' field centred on the spiral galaxy M 81 has been searched for emission-line objects using the prime focus wide field camera (WFC) of the 2.54 m Isaac...

    New Candidate Planetary Nebulae in the IPHAS Survey: the Case of Planetary Nebulae with ISM interaction
    We present the results of the search for candidate Planetary Nebulae interacting with the interstellar medium (PN-ISM) in the framework of the INT Photometric...

    New clues on outburst mechanisms and improved spectroscopic elements of the black hole binary V4641 Sagittarii*
    We present spectroscopic observations of the black hole binary V4641 Sagittarii, obtained between 2004 July 4 and 2005 March 28, which cover the minor outburst...

    New companions to nearby low-mass stars
    We present high-angular-resolution optical I-band imaging of 451 late K to mid-M nearby stars. These observations have been performed with Astralux and FastCam...

    New constraints on neutron star models of gamma ray bursts. I - EXOSAT observations of two gamma ray burst error boxes
    Two EXOSAT observations of gamma-ray burst error boxes and their possibly associated optical transients are discussed. No point source was detected in either...

    New constraints on the central mass contents of Omega Centauri from combined stellar kinematics and pulsar timing
    Aims. We performed a combined analysis of stellar kinematics with line-of-sight accelerations of millisecond pulsars (MSPs) to probe the mass content of Omega...
