Research Activities

To understand how planetary systems form, a detailed knowledge of the structure and evolution of these disks is required. Although, this is almost well understood for the regions of the disks observed with a spatial several AUs, the structure of these disks probed at a few AU scale and especially inward of 1 AU remains a puzzle. In recent years, it has become possible to directly spatially resolve the inner region of protoplanetary disks with optical interferometry technique. The context of my study is a multi-wavelength investigation of the protoplanetary disks evolution by determining their density distribution, their temperature distribution, the size and composition of the dust components and finally the kinematic of the gas. To do so, I have observed several YSOs using interferometers such as : AMBER/VLTI at K-band, MIDI/VLTI at N-band, PIONIER/VLTI at H-band and VEGA/CHARA at visible domain. I plan to keep observing during staying at IPM with these instruments combing with radiative transfer codes collaborating with Nice group in France, Brazilian group, IPAG group in Gronoble in France, Graz group in Austria, and Li?ge university in Belguim.

Present Research Project at IPM

Study of the inner region of protoplanetray disks around YSOs using optical/Infrared Interferometry.
