    Red giant stragglers and He white dwarfs in galactic globulars
    The evolutionary scenario concerning the production and the cooling of He white dwarfs is revisited and discussed. We show that, for a given star metallicity...

    Red Supergiants as Cosmic Abundance Probes: Massive Star Clusters in M83 and the Mass–Metallicity Relation of Nearby Galaxies
    We present an abundance analysis of seven super star clusters in the disk of M83. The near-infrared spectra of these clusters are dominated by red supergiants...

    Reddening Distribution across the Center of the Globular Cluster ω Centauri
    We present new medium-band uvby Strömgren and broadband VI photometry for the central regions of the globular cluster ω Cen. From this photometry we have...

    Redshift Determination and CO Line Excitation Modeling for the Multiply Lensed Galaxy HLSW-01
    We report on the redshift measurement and CO line excitation of HERMES J105751.1+573027 (HLSW-01), a strongly lensed submillimeter galaxy discovered in Herschel...

    Rejecting Astrophysical False Positives from the TrES Transiting Planet Survey: The Example of GSC 03885-00829
    Ground-based wide-field surveys for nearby transiting gas giants are yielding far fewer true planets than astrophysical false positives, some of which are...

    Relationship between Hubble Type and Spectroscopic Class in Local Galaxies
    We compare the Hubble type and the spectroscopic class of the galaxies with spectra in the Sloan Digital Sky Survey Data Release 7. As has long been known...

    Relative Alignment between the Magnetic Field and Molecular Gas Structure in the Vela C Giant Molecular Cloud Using Low- and High-density Tracers
    We compare the magnetic field orientation for the young giant molecular cloud Vela C inferred from 500 μm polarization maps made with the BLASTPol balloon-borne...

    Relativistic Outflow in CXOCDFS J033260.0-274748
    In this Letter we report the detection of a strong and extremely blueshifted X-ray absorption feature in the 1 Ms Chandra spectrum of CXOCDFS J033260.0-274748...

    Remnants of the Sagittarius Dwarf Spheroidal Galaxy around the Young Globular Cluster Palomar 12
    Photometry of a large field around the young globular cluster Palomar 12 has revealed the main sequence of a low surface brightness stellar system. This main...
