    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 the minimum mass for thermonuclear lithium burning in brown dwarfs
    The theory of substellar evolution predicts that there is a sharp mass boundary between lithium and non-lithium brown dwarfs, not far below the substellar-mass...

    New faint optical spectrophotometric standards: hot white dwarfs from the Sloan Digital Sky Survey
    The spectral energy distributions for pure-hydrogen (DA) hot white dwarfs can be accurately predicted by model atmospheres. This makes it possible to define...

    New Galactic supernova remnants discovered with IPHAS
    As part of a systematic search programme of a 10° wide strip of the northern Galactic plane, we present preliminary evidence for the discovery of four (and...

    New giant planet beyond the snow line for an extended MOA exoplanet microlens sample
    Characterizing a planet detected by microlensing is hard if the planetary signal is weak or the lens-source relative trajectory is far from caustics. However...

    New GTC spectroscopic data and a statistical study to better constrain the redshift of the BL Lac RGB J2243 + 203
    We present new spectroscopic data of the BL Lac RGB 2243 + 203, and its surroundings, obtained with the OSIRIS Multi Object Spectrograph (MOS) mounted in the...

    New insights into the role of AGNs in forming the cluster red sequence
    As a considerable investment of time from various telescope facilities was dedicated toward studying the Spiderweb protocluster at z = 2.2, it so far remains...

    New members in the Upper Scorpius association from the UKIRT Infrared Deep Sky Survey Early Data Release†
    We present the results of a 9.3-deg2 infrared (ZYJHK) survey in the Upper Scorpius association extracted from the UKIRT Infrared Deep Sky Survey (UKIDSS)...
