    A Synoptic View of the Subphotospheric Horizontal Velocity Flows in the Sun
    Ring diagram analysis, a technique of local helioseismology, has been applied to 120 regions of 15deg×15deg over the solar surface in order to study the mass...

    A Systematic Search of Zwicky Transient Facility Data for Ultracompact Binary LISA-detectable Gravitational-wave Sources
    Using photometry collected with the Zwicky Transient Facility, we are conducting an ongoing survey for binary systems with short orbital periods ( ${P}_{{\rm{b}...

    A Tale of a Rich Cluster at z ~ 0.8 as Seen by the Star Formation Histories of its Early-type Galaxies
    We present a detailed stellar population analysis for a sample of 24 early-type galaxies (ETGs) belonging to the rich cluster RX J0152.7-1357 at z = 0.83. We...

    A Tale of Two Disks: Mapping the Milky Way with the Final Data Release of APOGEE
    We present new maps of the Milky Way disk showing the distribution of metallicity ([Fe/H]), α-element abundances ([Mg/Fe]), and stellar age, using a sample of...

    A Tentative 114 minute Orbital Period Challenges the Ultracompact Nature of the X-Ray Binary 4U 1812-12
    We present a detailed time-resolved photometric study of the ultracompact X-ray binary candidate 4U 1812-12. The multicolor light curves obtained with HiPERCAM...

    A Third Massive Star Component in the σ Orionis AB System
    We report on the detection of a third massive star component in the σ Orionis AB system, traditionally considered as a binary system. The system has been...

    A Three-dimensional Study of Reconnection, Current Sheets, and Jets Resulting from Magnetic Flux Emergence in the Sun
    We present the results of a set of three-dimensional numerical simulations of magnetic flux emergence from below the photosphere and into the corona. The corona...

    A Three-dimensional View of the Remnant of Nova Persei 1901 (GK Per)
    We present a kinematical study of the optical ejecta of GK Per. It is based on proper-motion measurements of 282 knots from ~20 images spanning 25 years...
