Study of dust and ices properties in highly inclined protoplanetary disks

Thesis defense of Laurine Martinien - Wednesday, October 7th octobre at 10.00 am - Manuel Forestini room IPAG

Planets form in protoplanetary disks surrounding young stars. Composed of gas, dust, and ices, these disks are the location of grain growth, during which particles coagulate and grow from a few micrometers to bodies several thousand kilometers in size. However, the physical mechanisms driving this growth remain poorly constrained. The study of micrometer- and millimeter-sized dust provides valuable insights into the early stages of planet formation. In addition, ices (H2O, CO2, and CO) have (…)

Identifying the limits to exoplanets characterization with high-resolution spectro-imaging

Thesis defense of Steven Martos - October, Wednesday 14th at 2.00 pm - Manuel Forestini room IPAG

This thesis is situated within the field of exoplanet detection and characterization through the combination of high-contrast imaging and high-resolution spectroscopy. It focuses more specifically on molecular mapping, a post-processing method based on spectral cross-correlation, designed to extract the signal of faint companions at small angular separations. The overall objective is to identify the physical, instrumental, and methodological limits of this approach, and then to assess its (…)
