    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 B-type Binaries Characterisation Programme - II. VFTS 291: a stripped star from a recent mass transfer phase
    Recent studies of massive binaries with putative black hole companions have uncovered a phase of binary evolution that has not been observed before, featuring a...

    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 black widow pulsar J1641+8049 in the optical, radio, and X-rays
    PSR J1641+8049 is a 2 ms black widow pulsar with the 2.2 h orbital period detected in the radio and γ-rays. We performed new phase-resolved multiband photometry...

    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...

    The bursty star formation history of the Fornax dwarf spheroidal galaxy revealed with the HST
    We present a new derivation of the star formation history (SFH) of the dSph galaxy Fornax in two central regions, characterized by unprecedented precision and...

    The C+N+O Abundance of ω Centauri Giant Stars: Implications for the Chemical-enrichment Scenario and the Relative Ages of Different Stellar Populations
    We present a chemical-composition analysis of 77 red-giant stars in Omega Centauri. We have measured abundances for carbon and nitrogen, and combined our...

    The Carbon Star DY Persei May Be a Cool R Coronae Borealis Variable
    Optical and near-IR photometry suggests that the carbon star DY Persei exhibits fadings similar to those of R Coronae Borealis (RCB) variables. Photometric...
