The solid content of circumstellar disks is inherited from the interstellar medium: dust
particles of at most a micrometer in size. Protoplanetary disks are the environment where …

A large fraction of the protoplanetary disks observed with ALMA display multiple well-
defined and nearly perfectly circular rings in the continuum, in many cases with substantial …

The latest observation of HL Tau by ALMA revealed spectacular concentric dust rings in its
circumstellar disk. We attempt to explain the multiple ring structure as a consequence of …

Context. The global size and spatial distribution of dust is an important ingredient in the
structure and evolution of protoplanetary disks and in the formation of larger bodies, such as …

The formation of planetary cores must proceed rapidly in order for the giant planets to
accrete their gaseous envelopes before the dissipation of the protoplanetary gas disc (≲ 3 …

We perform local, vertically stratified shearing-box MHD simulations of protoplanetary disks
(PPDs) at a fiducial radius of 1 AU that take into account the effects of both Ohmic resistivity …

Circumstellar disks are thought to experience a rapid" transition" phase in their evolution that
can have a considerable impact on the formation and early development of planetary …

Circumstellar dust exists around several hundred main sequence stars. For the youngest
stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be …

We present the results of a high angular resolution (0 farcs 3≈ 40 AU) Submillimeter Array
survey of the 345 GHz (870 μm) thermal continuum emission from nine of the brightest, and …

We present new results from a significant extension of our previous high angular resolution
(0 farcs 3≈ 40 AU) submillimeter array survey of the 340 GHz (880 μm) thermal continuum …
