  1. TESS observations show frequent flaring and magnetic activity in PM J11183+1347
    TESS observations reveal 21 flares on M dwarf PM J11183+1347, including superflares exceeding 10^33 erg. Flare frequency follows a power law with high-energy events dominating total output.
  2. DM Tau disk shows non-thermal line broadening
    Bayesian analysis of molecular line observations confirms nonthermal broadening of 0.4 sound speeds in the DM Tau protoplanetary disk, providing evidence for turbulence.
  3. Milky Way circular velocity measured from stellar abundances
    A new data-driven method measures the Milky Way's circular velocity using element abundance gradients, deriving rotation parameters at the solar radius.
  4. Three ultra-faint Milky Way satellite candidates identified
    Three ultra-faint Milky Way satellites identified in DELVE survey data, including the faintest known satellite in the outer halo and an ambiguous compact system.
  5. Tomographic line analysis identifies possible embedded planets in disks
    Tomographic analysis of molecular line observations enables detection of embedded planets in protoplanetary disks, revealing multiple planet candidates in HD 135344B and MWC 758.
  6. Large protoplanetary disks show widespread non-Keplerian gas motions
    Two-dimensional kinematic mapping of 15 protoplanetary disks reveals ubiquitous non-Keplerian deviations including spiral structures, with systematic differences between disk classifications.
  7. Vertical gas flows are widespread in protoplanetary disks
    Study of vertical gas flows in 14 protoplanetary disks using ALMA observations reveals ubiquitous vertical motions driven by diverse physical mechanisms during planet formation.
