17. The role of AO in star formation: a closer look to protoplanetary disks

Elisabetta Rigliaco (Istituto Nazionale di Astrofisica (INAF))

Star formation, and in particular formation, evolution and dissipation of protoplanetary disks is a hot topic in nowadays astronomy because it bridges the classic study of star formation to the new discovery and characterization of extrasolar planets.
In this talk I will review the role of AO in star formation, focusing in particular on how our understanding on formation, evolution and...

43. Looking for binary planets, satellites and disks around exoplanets

In the past decades the exoplanets hunting has improved so much that thousands of planets have been confirmed and partially characterized. Both indirect and direct detecting techniques have filled this huge sample, from the terrestrial to the gas giant and brown dwarf regime. One further step would be to detect exomoons and disks/rings around exoplanets, that we expect to be there taking as a...

26. AO-assisted integral-field and long slit spectroscopy: investigating brown dwarfs and exoplanets

Valentina D'Orazi (Istituto Nazionale di Astrofisica (INAF))

In this contribution I will present and discuss the exploitation of AO-assisted
spectroscopic instrumentation (both integral field and long-slit) in order to detect and characterise exoplanet and brown dwarf population.
Fundamental information on mass, separation, age, surface gravity and clouds (more in general atmospheric properties) can be inferred via this kind of observations,...

32. Planet formation, from ALMA to ERIS

Davide Fedele (Istituto Nazionale di Astrofisica (INAF))

In the last years, ALMA has revolutionised the field of plant formation.
The high angular resolution campaigns are showing a great variety of protoplanetary disk morphologies, revealing the presence of rings, gaps, cavities and spirals.
Such sub-structures suggest the presence of young giant planets that perturbs the mass distribution and dynamics of gas and dust in the disk.
And yet, a...

33. Planet formation: from SPHERE to ERIS

Antonio Garufi (Istituto Nazionale di Astrofisica (INAF))

In the last years, SPHERE has revolutionized the field of planet formation. Also thanks to Subaru/HiCiao, GPI, and VLT/NACO, the number of protoplanetary disks observed in near-IR scattered light now amounts to more than 100. This census reveals, similarly to ALMA, the high occurrence of disk sub-structures that are likely due to the gravitational interaction with (forming) planets. Yet, the...
