Non-ideal MHD shearing-box simulations with a new damping scheme yield power-law scalings for wind-driven accretion rates based on midplane plasma beta, ambipolar Elsasser number, and active layer thickness that match results within a factor of 2-3.

Accretion increases observable water mass in disks by expanding the emitting area via higher central luminosity, while viscous heating has no effect.
Compact protoplanetary discs disperse inside-out when photoevaporation is limited to their cut-off radius, unlike the outside-in dispersal seen in extended discs.
ALMA observations of 100 Ophiuchus discs show substructures linked to giant planet formation are common in discs above 10 Earth masses of dust and increase from Class I to Class II stages.
Halos in Elias 2-24, IM Lup, and DM Tau hold 20-30% of total dust mass with cm-sized grains, helping resolve the disk mass-budget problem even though drift and growth timescales are shorter than disk ages.
Dual-frequency monitoring detects 20 radio sources in the Coronet Cluster, showing steeper spectral indices in Class 0/I YSOs than in Class II and ubiquitous variability independent of stage.
Stronger radiation environments produce more massive, hotter protostellar discs whose fragments are large and disruptive rather than planetary-mass.
Gaia astrometric quality metrics and a machine-learning classifier trained on known exoplanet hosts identify candidate stars with debris disks likely to host undetected planets.

Beyond the $\alpha$ model: scaling the wind-driven accretion rate in protoplanetary disks using systematic non-ideal magnetohydrodynamical simulations
Non-ideal MHD shearing-box simulations with a new damping scheme yield power-law scalings for wind-driven accretion rates based on midplane plasma beta, ambipolar Elsasser number, and active layer thickness that match results within a factor of 2-3.
