This thesis work focuses on the study at the astronomical scale of young stars and their protoplanetary disks with infrared interferometry. This work includes both observational and instrumental aspects. In the observational part, we focus on the acc

The star formation process usually proceeds with protoplanetary disks. These disks contain a mixture of gas, accounting for 99 % of the disk mass, and of solid particles called dust grains (1 % of the disk mass). These grains, initially at sub-micro

To this day, thousands of planets have been identified outside of our own solar system. Theirformation is thus not an unlikely occurence. A number of still-forming young stars are also known,circled by remnants of gas and dust which are shaped by cen

Les observations de centaines de systèmes d’exoplanètes nous ont fourni un large échantillon de configurations orbitales. Les périodes orbitales figurent parmi les données les mieux connues et les plus étonnantes. Les Super-Terres, ces planè

Observations of hundreds of exoplanetary systems have produced a huge sample of orbital configurations, and the orbital periods are one of their better constrained and most astonishing properties. A common type of exoplanets are the Super-Earths, whi

Dans les disques protoplanétaires, les grains micrométriques croissent jusqu'à atteindre des tailles de planétésimaux avant de finalement former des planètes. Cependant,des études dynamiques ont montré qu'une fois que les grains atteignent un

In protoplanetary discs, micron-sized grains should grow up to planetesimal sizes in order to ultimately form planets. However, dynamical studies show that once they reach a critical size, they drift rapidly into the accreting star. This is known as
