  1. Data-driven Derivation of Stellar Properties from Photometric Time Series Data Using Convolutional Neural Networks

    Publication
    Stellar variability is driven by a multitude of internal physical processes that depend on fundamental stellar properties. These properties are our bridge to reconciling stellar observations with stellar …

  2. The 3D Galactocentric Velocities of Kepler Stars: Marginalizing Over Missing Radial Velocities

    Publication
    Precise Gaia measurements of positions, parallaxes, and proper motions provide an opportunity to calculate 3D positions and 2D velocities (i.e., 5D phase-space) of Milky Way stars …

  3. Age-dating Red Giant Stars Associated with Galactic Disk and Halo Substructures

    Publication
    The vast majority of Milky Way stellar halo stars were likely accreted from a small number (≲3) of relatively large dwarf galaxy accretion events. However, the timing of …

    Publication
    The vast majority of Milky Way stellar halo stars were likely accreted from a small number (≲3) of relatively large dwarf galaxy accretion events. However, the timing of …

  5. Calibration of the Hα Age–Activity Relation for M Dwarfs

    Publication
    In this work, we calibrate the relationship between Halpha emission and M dwarf ages. We compile a sample of 892 M dwarfs with Halpha equivalent width (HaEW) measurements …

  6. Astraea: Predicting Long Rotation Periods with 27 Day Light Curves

    Publication
    The rotation periods of planet-hosting stars can be used for modeling and mitigating the impact of magnetic activity in radial velocity measurements and can help constrain the …

  7. Towards precise stellar ages: combining isochrone fitting with empirical gyrochronology

    Publication

  8. Inference of Stellar Parameters from Brightness Variations

    Publication
    It has been demonstrated that the time variability of a star's brightness at different frequencies can be used to infer its surface gravity, radius, mass, and age …
