    The APOKASC Catalog: An Asteroseismic and Spectroscopic Joint Survey of Targets in the Kepler Fields
    We present the first APOKASC catalog of spectroscopic and asteroseismic properties of 1916 red giants observed in the Kepler fields. The spectroscopic...

    The Arches cluster revisited. II. A massive eclipsing spectroscopic binary in the Arches cluster
    We have carried out a spectroscopic variability survey of some of the most massive stars in the Arches cluster, using K-band observations obtained with SINFONI...

    The Arches cluster revisited. III. An addendum to the stellar census
    The Arches is one of the youngest, densest and most massive clusters in the Galaxy. As such it provides a unique insight into the lifecycle of the most massive...

    The BaSTI Stellar Evolution Database: models for extremely metal-poor and super-metal-rich stellar populations
    We present an extension of the BaSTI (Bag of Stellar Tracks and Isochrones) stellar evolution database to extremely metal-poor (Z = 10-5) and super-metal-rich...

    The blue supergiant Sher 25 and its intriguing hourglass nebula
    The blue supergiant Sher25 is surrounded by an asymmetric, hourglass-shaped circumstellar nebula. Its structure and dynamics have been studied previously...

    The Brightest Young Star Clusters in NGC 5253.
    The nearby dwarf starburst galaxy NGC 5253 hosts a number of young, massive star clusters, the two youngest of which are centrally concentrated and surrounded...
