Protoplanetary disks exhibit a vertical gradient in angular momentum, rendering them
susceptible to the vertical shear instability (VSI). The most important condition for the onset …

WL 17 is a Class I object and was considered to have a ring–hole structure. We analyzed
the structure around WL 17 to investigate the detailed properties of this object. We used …

Context. The initial particle growth in protoplanetary disks is limited by a bouncing barrier at
submillimeter wavelengths. Bouncing leads to tribocharging and the electrostatic attraction …

Context. The first hydrostatic core (FHSC) phase is a brief stage in the protostellar evolution
that is difficult to detect. Its chemical composition determine that of later evolutionary stages …

Context. Understanding circumstellar disks is of prime importance in astrophysics; however,
their birth process remains poorly constrained due to observational and numerical …

Context. Signposts of early planet formation are ubiquitous in substructured young discs.
Dense, hot, and high-pressure regions that formed during the gravitational collapse process …

Aims. The goal of this work is to comprehensively characterize the impact of stellar
multiplicity on Class II disks in the L1641 and L1647 regions of Orion A (~ 1-3 Myr), part of …

Protoplanetary disks exhibit a vertical gradient in angular momentum, rendering them

Our understanding of planet formation in the gas and dust disks surrounding newborn stars
is crucially dependent on the accuracy and complexity of numerical models. Gas and dust …

Protoplanetary disks are formed around the protostars. These disks are composed of gas
and solid small particles called dust particles. In disks, the collisional growth of small dust …
