TNG is operative since 20 years. We will briefly review the
changes occurred in these 20 years and how the current focal plane
instrumentation has been updated to face the open problems of
modern astrophysics. A look to the near future is also indispensable:
inputs from the community are welcome.
The physical structure and processes in the inner regions of protoplanetary disks within 5 au from the source are still poorly constrained, yet they are key for understanding planet formation. Only recently, IR interferometers have been able to perform the first statistical study of the dust in the inner disk, but a similar study on the gas is still lacking.
In this talk, I will present the...
The spin evolution of classical TTauri stars (CTTS) represents a puzzling problem. Since they are still contracting and accreting, these protostars would be expected to spin-up at breakup speed in a few million years. On the other hand, as soon as they emerge from the Class 0-I embedded phases, they are observed to rotate with periods between 1-10 days, well below their breakup limit. In...
We present recent results on accretion properties of low-mass stars in the metal-poor star forming region (SFR) LH95 within the Large Magellanic Cloud (LMC). Using optical and Halpha photometry obtained with the Hubble Space Telescope, we identify, within the initial catalogue of about 25000 sources, 245 bona fide pre-main sequence (PMS) stars with Halpha excess emission, for which we measure...
A multi-band investigation of the emission from young stars with disks allows us to obtain a complete characterization of these complex systems, accounting for their accretion and outflow activity.
All the components contributing to the emission can strongly influence also the evolution of their disks and possibly the formation of exo-planetary systems.
Combining multi-wavelength...
