The disks that orbit young stars are the essential conduits and reservoirs of material for star
and planet formation. Their structures, meaning the spatial variations of the disk physical …

Abstract Herbig Ae/Be stars are young contracting stars on the radiative track in the HR
diagram on their way to the main sequence. These stars provide a valuable link between …

High dust density in the midplane of protoplanetary disks is favorable for efficient grain
growth and can allow fast formation of planetesimals and planets, before disks dissipate …

To determine the origin of the spiral structure observed in the dust continuum emission of
Elias 2–27 we analyze multiwavelength continuum ALMA data with a resolution of∼ 0 farcs …

The canonical theory for planet formation in circumstellar disks proposes that planets are
grown from initially much smaller seeds,,,–. The long-considered alternative theory proposes …

Abstract Observations with the Atacama Large Millimeter/Submillimeter Array (ALMA) have
dramatically improved our understanding of the site of exoplanet formation: protoplanetary …

The FU Orionis–type objects (FUors) are low-mass pre-main-sequence stars undergoing a
temporary but significant increase of mass accretion rate from the circumstellar disk onto the …

Recent spatially-resolved observations of protoplanetary disks revealed a plethora of
substructures, including concentric rings and gaps, inner cavities, misalignments, spiral …

Theoretical studies suggest that a giant planet around the young star MWC 758 could be
responsible for driving the spiral features in its circumstellar disk. Here, we present a deep …

Hydrodynamical simulations show that a pair of spiral arms can form in the disk around a
rapidly growing young star and that the arms are crucial in transporting angular momentum …
