    Timing the Evolution of the Galactic Disk with NGC 6791: An Open Cluster with Peculiar High-α Chemistry as Seen by APOGEE
    We utilize elemental-abundance information for Galactic red giant stars in five open clusters (NGC 7789, NGC 6819, M67, NGC 188, and NGC 6791) from the Apache...

    To clump or not to clump. The impact of wind inhomogeneities on the optical and NIR spectroscopic analysis of massive OB stars
    Context. Winds of massive stars have density inhomogeneities (clumping) that may affect the formation of spectral lines in different ways, depending on their...

    TOI-150: A Transiting Hot Jupiter in the TESS Southern CVZ
    We report the detection of a hot Jupiter ({M}p={1.75}-0.17+0.14 {M}{{J}}, R p = 1.38 ± 0.04 R J) orbiting a middle-aged star ({log}g={4.152}-0.043+0.030) in the...

    Towards a more complete sample of binary central stars of planetary nebulae with Gaia
    Context. Many if not most planetary nebulae (PNe) are now thought to be the outcome of binary evolutionary scenarios. However, only a few percent of the PNe in...

    Towards a new classification of galaxies: principal component analysis of CALIFA circular velocity curves
    We present a galaxy classification system for 238 (E1-Sdm) CALIFA (Calar Alto Legacy Integral Field Area) galaxies based on the shapes and amplitudes of their...

    Tracing Chemical Evolution over the Extent of the Milky Way's Disk with APOGEE Red Clump Stars
    We employ the first two years of data from the near-infrared, high-resolution SDSS-III/APOGEE spectroscopic survey to investigate the distribution of...
