    Ground-based Multisite Observations of Two Transits of HD 80606b
    We present ground-based optical observations of the 2009 September and 2010 January transits of HD 80606b. Based on three partial light curves of the 2009...

    GTC/CanariCam Mid-IR Imaging of the Fullerene-rich Planetary Nebula IC 418: Searching for the Spatial Distribution of Fullerene-like Molecules
    We present seeing-limited narrow-band mid-IR GTC/CanariCam images of the spatially extended fullerene-containing planetary nebula (PN) IC 418. The narrow-band...

    H II Regions Within a Compact High Velocity Cloud. A Nearly Starless Dwarf Galaxy?
    Within the SECCO survey we identified a candidate stellar counterpart to the Ultra Compact High Velocity Cloud (UCHVC) HVC274.68+74.70-123 that was suggested by...

    H α fluxes and extinction distances for planetary nebulae in the IPHAS survey of the northern galactic plane
    We report H α filter photometry for 197 Northern hemisphere planetary nebulae (PNe) obtained using imaging data from the IPHAS survey. H α+[N II] fluxes were...

    H α morphologies of star clusters: a LEGUS study of H II region evolution time-scales and stochasticity in low-mass clusters
    The morphology of H II regions around young star clusters provides insight into the time-scales and physical processes that clear a cluster's natal gas. We...

    H-band discovery of additional second-generation stars in the Galactic bulge globular cluster NGC 6522 as observed by APOGEE and Gaia
    We present an elemental abundance analysis of high-resolution spectra for five giant stars spatially located within the innermost regions of the bulge globular...

    HD 20329b: An ultra-short-period planet around a solar-type star found by TESS
    Context. Ultra-short-period (USP) planets are defined as planets with orbital periods shorter than one day. This type of planets is rare, highly irradiated, and...

    Heavy Element Nucleosynthesis in the Brightest Galactic Asymptotic Giant Branch Stars
    We present updated calculations of stellar evolutionary sequences and detailed nucleosynthesis predictions for the brightest asymptotic giant branch (AGB) stars...

    Heavy-element Abundances in P-rich Stars: A New Site for the s-process?
    The recently discovered phosphorus-rich stars pose a challenge to stellar evolution and nucleosynthesis theory, as none of the existing models can explain their...
