Circumstellar Disks seen by NOEMA
The sudy of proto-planetary disks has so far focussed on the largest, brightest objects that extends over 100s of au. However, like planetary systems, protoplanetary disks exhibit a large diversity in size, and many protoplanetary disks are much smaller than the one studied so far. Previous studies in continuum revealed very compact dusty disks, with radii of only 10 to 20 au. Taking advantage of the new capabilities of NOEMA, the NOrthern Extended Millimeter Array, we have started to explore such disks, in particular their molecular content to characterize the gaseous counterpart. After presenting the capabilities of the recently completed NOEMA, I will discuss some preliminary results of these studies that reveals a striking diversity.
