Paper Abstract

In the following years, the VLTI will offer new observing capabilities at high angular resolution: a large number of observing nights with a better spatial frequencies coverage, improved sensibilities and accuracy, and various observing modes covering near and thermal infrared. However, both the choice between all the involved observing parameters and the still partial information of intensity interferometry (compared to classical imaging) require specific study, dedicated to each astronomical interest. We discuss here the interest of long baseline interferometry to investigate the circumstellar environment of stars, as they evolve from the pre-main sequence stage with massive disks to the main sequence tenuous `debris' disks. These transient environments give us very interesting information on the physics of planetary formation and the dynamics of young planetary systems. We will identify the specific information the long baseline interferometry can provide, and how it would impact this issue. We derive then the required observing capabilities and discuss how VLTI will fulfill such requirements: what will be the impact of VLTI on (proto)planetary disks studies, with which instrument and which observing mode?
