    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...

    Outflows from Evolved Stars: The Rapidly Changing Fingers of CRL 618
    Our ultimate goal is to probe the nature of the collimator of the outflows in the pre-planetary nebula CRL 618. CRL 618 is uniquely suited for this purpose...

    Outflows of Very Ionized Gas in the Centers of Seyfert Galaxies: Kinematics and Physical Conditions
    Mid-resolution spectra are used to deduce the size and kinematics of the coronal region in a sample of Seyfert galaxies by means of observations of the [Fe XI]...

    Outside-In Disk Evolution in the Large Magellanic Cloud
    From the analysis of the color-magnitude diagrams and color functions of four wide LMC fields located from ~=2 to 6 kpc from the kinematic center of the LMC we...
