We review recent observational and theoretical results on the relationship between circumstellar accretion disks and jets in young stellar objects. We then present a theoretical framework that interprets jets as accretion-powered, centrifugally driven winds from magnetized accretion disks. Recent progress in the numerical simulation of such outflows is described. We also discuss the structure of the underlying magnetized protostellar disks, emphasizing the role that large-scale, open magnetic fields can play in angular momentum transport.

  1. Asymmetry in the protostellar system HOPS 198: Evidence for the evolution of outflow opening angle driven by density of the surrounding core

    astro-ph.SR 2026-08 conditional novelty 6.0 of 10

    Observations and a pressure-balance model of HOPS 198 link a 2.9x difference in inferred core pressure to the 80 versus 30 degree asymmetry in outflow opening angle, supporting a density-driven evolution of outflow widths.

  2. Accretion across scales: streamers, surface-layer transport, and rapid replenishment in young protoplanetary discs

    astro-ph.EP 2026-08 conditional novelty 6.0 of 10

    Cloud-fed ideal-MHD zoom-in simulations of nine young stars show discs are replenished on ~10,000-year timescales via surface-layer accretion and can be truncated by massive streamers.

  3. GeV {\gamma}-ray emission in the low-mass star-forming region AFGL 490

    astro-ph.HE 2026-05 unverdicted novelty 6.0 of 10

    Discovery of extended GeV gamma-ray emission from AFGL 490, with the protostellar jet identified as the likely particle accelerator rather than stellar winds.

  4. Connecting Planetary Composition with Formation: a New Paradigm Emerges

    astro-ph.EP 2025-05 unverdicted novelty 3.0 of 10

    A synthesis review argues that MHD disk winds, not turbulence, dominate disk evolution and planet formation, linking observed disk structures to exoplanet composition and orbits.
