The fore coming SHARK-VIS high resolution imaging camera will exploit the LBT adaptive optics performance at visible wavelengths (400-1000 nm) yielding a diffraction limited psf core with a FWHM of 18 mas at H-alpha. This resolution together with the high frame rate and the use of peculiar post processing techniques will allow the observer to reach contrast of 1e-5 at 100 mas on sources...
Cygnus OB2 is the most massive stellar association within 2 kpc from the Sun. Given its large content of massive stars, counting tens of O and 3 WR stars, and thousands of young low mass stars, Cygnus OB2 is the best target to study how massive stars affect the star formation process in the parental cloud and the evolution of nearby protoplanetary disks.
I will present the results of our study...
I will present results from a multi-wavelength and multi-tracer campaign to observe the evolution of protoplanetary disks at 0.01-10 au at the time of exoplanet formation. The backbone of this work is the combined analysis of recent surveys of moderate-to-high-resolution spectroscopy (R ~ 700- 100,000) of molecular gas emission at infrared wavelengths (2.9-35 um), as collected from a suite of...
Infrared observations of edge-on protoplanetary disks clearly show the presence of absorption features assigned to refractory dust grains and to solid phase molecules which form the so called icy grain mantles. It is generally accepted that in protoplanetary disks dust grains suffer from thermal and energetic processing (i.e. UV and ion irradiation) caused by the central protostar.

V4046 Sgr is a close binary with accretion signature.
GSC 07396-00759 is instead a very active but not accreting M1-type star.
These three form a dynamically bound system, likely member of the Beta Pictoris Moving Group.
Although V4046 Sgr is surrounded by a gas-rich disk, the characteristics of the newly detected GSC disk all together tend to favor an evolved/debris disk nature over a...
The recipe to make a habitable planet like our own Earth requires a relatively small rocky planet,
at the right distance from the host star, with a not-too-thick atmosphere which should be rich in volatiles
and capable of developing complex organic molecules chemistry. Searches for exoplanets have shown
a large degree of diversity among planetary systems, but have left still unanswered the...
The GENESIS-SKA project is supported as PRIN-INAF and its main goal is to study dust evolution, planet formation, and pre-biotic chemical complexity, in the context of preparation of SKA Key Programmes. The funding PRIN-INAF also accounts for communication, public and industrial outreach of the projects’ scientific goals and results. This is the reason why GENESIS-SKA has a dedicate outreach...
