Context. In the past few years, there has been a rise in the detection of streamers,
asymmetric flows of material directed toward the protostellar disk with material from outside …

The demographic of circumstellar disks, the birthplaces of planets, is diverse and rich in
disks featuring rings, gaps, spirals, filaments, and arcs. Many studies revealing these disk …

Spatially resolved structures in protoplanetary disks hint at unseen planets. Previous
imaging observations of the transitional disk around MWC 758 revealed an inner cavity, a …

The concentric gaps and rings commonly observed in protoplanetary disks in millimeter
continuum emission have lent the impression that planet formation generally proceeds …

Close encounters between young stellar objects in star-forming clusters are expected to
markedly perturb circumstellar disks. Such events are witnessed in numerical simulations of …

Deciphering the spatial and temporal evolution of chondrules allows for a better
understanding of how asteroidal seeds formed, migrated, and eventually accreted into …

DR Tau has been noted for its unusually high variability in comparison with other T Tauri
stars. Although it is one of the most extensively studied pre-main-sequence stars …

Spiral arm structures seen in scattered-light observations of protoplanetary disks can
potentially serve as signposts of planetary companions. They can also lend unique insights …

We investigate the formation of protoplanetary disks around nine solar-mass stars formed in
the context of a (40 pc) 3 Giant Molecular Cloud model, using ramses adaptive mesh …

Episodic accretion has been used to explain the wide range of protostellar luminosities, but
its origin and influence on the star-forming process are not yet fully understood. We present …
