Descripción
We have obtained metallicity estimates for a sample of A/F-type stars that appear to be members of the recently discovered Monoceros Stream. This sample of candidate main-sequence turn-off stars was chosen from the Sloan Digitized Sky Survey southern program spectra. The average metallicity, <[Fe/H]> = -1.37 ± 0.04, is consistent with the abundance of six suspected Monoceros Stream globular clusters and with that of the metal-weak thick disk. There is some suggestion that the Monoceros turn-off stars are younger than the oldest population of stream globular clusters.

    Identification of Superclusters and their Properties in the Sloan Digital Sky Survey
    Superclusters are the largest massive structures in the cosmic web on tens to hundreds of megaparsecs (Mpc) scales. They are the largest assembly of galaxy clusters in the Universe. Apart from a few detailed studies of such structures, their evolutionary mechanism is still an open question. In order to address and answer the relevant questions, a

    Rapid multiwavelength variability reveals jet emission in the black hole binary V404 Cygni in quiescence
    Spitzer Space Telescope observations of several quiescent black hole low mass X-ray binaries (LMXBs) have shown mid-infrared excesses above the emission of a companion star. The excess has been proposed to originate from either a relativistic jet or circumbinary disk. If the mid-IR originates in a jet, then it probes the region closest to the black

    KIC 9163796 - Age determination by asteroseismic grid modelling for an oscillating red giant binary
    The age of a star cannot be measured but only inferred from observational quantities related to age. A wellknown stellar age greatly impacts our understanding of evolution on much larger scales, such as exoplanetary systems or the history of the Milky Way. For stars in the red-giant phase, comparison of observations with evolutionary models
