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 formation of protostars and their disks has been understood as the result of the
gravitational collapse phase of an accumulation of dense gas that determines the mass …

Stars are among the most fundamental structures of our Universe. They comprise most of the
baryonic and luminous mass of galaxies; synthesize heavy elements; and inject mass …

MHD models and the observation of accretion streamers confirmed that protostars can
undergo late accretion events after the initial collapse phase. To provide better constraints …

Context. The origin of the stellar initial mass function (IMF) and its relation with the core mass
function (CMF) are actively debated issues with important implications in astrophysics …

We present dynamical properties of 294 cores embedded in twelve IRDCs observed as part
of the ASHES Survey. Protostellar cores have higher gas masses, surface densities, column …

The initial conditions found in infrared dark clouds (IRDCs) provide insights on how high-
mass stars and stellar clusters form. We have conducted high-angular resolution and high …

Aims. The processes that determine the stellar initial mass function (IMF) and its origin are
critical unsolved problems, with profound implications for many areas of astrophysics. The …

Context. Among the most central open questions regarding the initial mass function (IMF) of
stars is the impact of environment on the shape of the core mass function (CMF) and thus …

Arc-and tail-like structures associated with disks around Herbig stars can be a consequence
of infall events occurring after the initial collapse phase of a forming star, consistent with the …
