    Optically Faint Massive Balmer Break Galaxies at z > 3 in the CANDELS/GOODS Fields
    We present a sample of 33 Balmer break galaxies (BBGs) selected as Hubble Space Telescope/F160W dropouts in the deepest CANDELS/GOODS fields (H ≳ 27.3 mag) but...

    Orbital and Physical Properties of the σ Ori Aa, Ab, B Triple System
    We provide a complete characterization of the astrophysical properties of the σ Ori Aa, Ab, B hierarchical triple system and an improved set of orbital...

    Orbital Torus Imaging: Using Element Abundances to Map Orbits and Mass in the Milky Way
    Many approaches to galaxy dynamics assume that the gravitational potential is simple and the distribution function is time invariant. Under these assumptions...

    Oscillations in the Photosphere of a Sunspot Umbra from the Inversion of Infrared Stokes Profiles
    We report on the detection of magnetic field strength and velocity oscillations in the photosphere of a sunspot umbra. Our analysis is based on the inversion of...

    Outcome of Six Candidate Transiting Planets from a TrES Field in Andromeda
    Driven by the incomplete understanding of the formation of gas giant extrasolar planets and of their mass-radius relationship, several ground-based, wide-field...

    Outflows from Active Galactic Nuclei: Kinematics of the Narrow-line and Coronal-line Regions in Seyfert Galaxies
    As part of an extensive study of the physical properties of active galactic nuclei (AGNs) we report high spatial resolution near-IR integral-field spectroscopy...
