    Anomalously Low-metallicity Regions in MaNGA Star-forming Galaxies: Accretion Caught in Action?
    We use data from 1222 late-type star-forming galaxies in the SDSS IV Mapping Nearby Galaxies at Apache Point Observatory survey to identify regions in which the...

    Antitruncation of Disks in Early-Type Barred Galaxies
    The disks of spiral galaxies are commonly thought to be truncated: the radial surface brightness profile steepens sharply beyond a certain radius (3-5 inner...

    Are C60 Molecules Detectable in Circumstellar Shells of R Coronae Borealis Stars?
    The hydrogen-poor, helium-rich, and carbon-rich character of the gas around R Coronae Borealis (RCB) stars has been suggested to be a site for formation of C60...
