The Keplerian Disk, Envelope, and Streamers Surrounding an Early O-type Protostar in the Sagittarius C Cloud of the Central Molecular Zone

The Astrophysical Journal
Disk-mediated accretion is central to theories of massive star formation, setting the initial conditions for their evolution. Yet observations of Keplerian disks around early O-type protostars remain scarce, as they are often blended into complex ...

The Extent of Solar Energetic Particle Irradiation in the Sun’s Protoplanetary Disk

The Astrophysical Journal
Solar flares emit X-rays and high-energy (MeV to GeV) ions called solar energetic particles (SEPs). Astronomical observations show solar-mass protostellar fluxes are a factor Φ ≈ 3 × 10 ^2 –3 × 10 ^3 times higher than the present-day Sun.
