Protoplanetary disks are quasi-steady structures whose evolution and dispersal determine the environ-ment for planet formation. I review the theory of protoplanetary disk evolution and its connection ...
The baroclinic instability in the context of layered accretion. Self-sustained vortices and their magnetic stability in local compressible unstratified models of protoplanetary disks

Context. Turbulence and angular momentum transport in accretion disks remain a topic of debate. With the realization that dead zones are robust features of protoplanetary disks, the search for hydrody...

We present the full results of our 3-year long Submillimeter Array survey of protoplanetary disks in the Orion Nebula Cluster. We imaged 23 fields at 880 microns and 2 fields at 1330 microns, covering...
The (sub-)millimeter SED of protoplanetary disks in the outskirts of the Orion Nebula Cluster

We present the sub-mm/mm SED for a sample of eight young circumstellar disks in the outer regions of the Orion Nebula Cluster.
Short Lifetime of Protoplanetary Disks in Low-metallicity Environments

We studied near-infrared disk fractions of six young clusters in the low-metallicity environments with [O/H$] \sim -0.7$ using deep $JHK$ images with Subaru 8.2\,m telescope.
