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 …

Star formation is a multi-scale, multi-physics problem ranging from the size scale of
molecular clouds (∼ 10 ∼10 s pc) down to the size scales of dense prestellar cores (∼ 0.1 …

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 …

We solve the equations of two-dimensional hydrodynamics describing a circumbinary disk
accreting onto an eccentric, equal-mass binary. We compute the time rate of change of the …

We report spectro-polarimetric results of an observational campaign of the bright neutron
star low-mass X-ray binary Cyg X-2 simultaneously observed by IXPE, NICER, and …

We present our current understanding of the formation and early evolution of protostars,
protoplanetary disks, and the driving of outflows as dictated by the interplay of magnetic …

Using high-resolution hydrodynamics simulations, we show that equal-mass binaries
accreting from a circumbinary disk evolve toward an orbital eccentricity of e≃ 0.45, unless …

While it is widely accepted that planets are formed in protoplanetary disks, there is still much
debate on when this process happens. In a few cases protoplanets have been directly …

We characterize protostellar multiplicity in the Orion molecular clouds using Atacama Large
Millimeter/submillimeter Array 0.87 mm and Very Large Array 9 mm continuum surveys …

Stars collect most of their mass during the protostellar stage, yet the accretion luminosity and
stellar parameters, which are needed to compute the mass accretion rate, are poorly …
