    TrES-4: A Transiting Hot Jupiter of Very Low Density
    We report the discovery of TrES-4, a hot Jupiter that transits the star GSC 02620-00648 every 3.55 days. From high-resolution spectroscopy of the star, we...

    TrES-5: A Massive Jupiter-sized Planet Transiting a Cool G Dwarf
    We report the discovery of TrES-5, a massive hot Jupiter that transits the star GSC 03949-00967 every 1.48 days. From spectroscopy of the star we estimate a...

    Trojans in the Solar Neighborhood
    About 20% of stars in the solar vicinity are in the Hercules stream, a bundle of stars that move together with a velocity distinct from the Sun. Its origin is...

    Turbulent Gas in Lensed Planck-selected Starbursts at z ∼ 1-3.5
    Dusty star-forming galaxies at high redshift (1 < z < 3) represent the most intense star-forming regions in the universe. Key aspects to these processes are the...

    Twist, Writhe, and Helicity in the Inner Penumbra of a Sunspot
    The aim of this work is the determination of the twist, writhe, and self-magnetic helicity of penumbral filaments located in an inner sunspot penumbra. For this...

    Two Distinct Ancient Components in the Sculptor Dwarf Spheroidal Galaxy: First Results from the Dwarf Abundances and Radial Velocities Team
    We have found evidence for the presence of two distinct ancient stellar components (both >=10 Gyr old) in the Sculptor dwarf spheroidal galaxy. We used the ESO...

    Two Super-Earths Orbiting the Solar Analog HD 41248 on the Edge of a 7:5 Mean Motion Resonance
    There are a growing number of multi-planet systems known to be orbiting their host stars with orbital periods that place them in mean motion resonances (MMRs)...

    Two Ultra-faint Milky Way Stellar Systems Discovered in Early Data from the DECam Local Volume Exploration Survey
    We report the discovery of two ultra-faint stellar systems found in early data from the DECam Local Volume Exploration survey (DELVE). The first system...
