    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 Bright M Dwarfs Hosting Ultra-Short-Period Super-Earths with Earth-like Compositions
    We present observations of two bright M dwarfs (TOI-1634 and TOI-1685: J = 9.5-9.6) hosting ultra-short-period (USP) planets identified by the TESS mission. The...

    Two close binaries across the hydrogen-burning limit in the Praesepe open cluster
    We present Keck I/OSIRIS and Keck II/NIRC2 adaptive optics imaging of two member candidates of the Praesepe stellar cluster (d = 186.18 ± 0.11 pc; 590-790 Myr)...

    Two decades of optical timing of the shortest-period binary star system HM Cancri
    The shortest-period binary star system known to date, RX J0806.3+1527 (HM Cancri), has now been observed in the optical for more than two decades. Although it...
