Spectral Key features of Young stellar objects: Wind-Accretion LinKs Explored in the infraRed (PI: J.M. Alcalà)
The Skywalker project tackles a key topic of star formation, namely the mechanisms leading to the evolution and dispersal of protoplanetary disks in low-mass (0.1-2M⊙) young stellar objects (YSOs), from the very early proto-stellar phase to the final dispersal stage. We pursue our goals within the framework of the JEDI (JEts and Disks@INAF) collaboration (Scheda Bacciotti), exploiting a large spectro-imaging data-base collected by our team using space (JWST, HST) and ground-based (VLT, LBT, TNG) facilities, in synergy with ALMA. The massive use of a so far unexploited spectral range, i.e. that of JWST, in combination with more traditional NIR/optical wavelengths, will make it possible to dramatically extending our studies to protostars (10^4-10^5 yr), i.e. the youngest YSOs.
Aims of the project
Aims of the project
Key goals of SKYWALKER are the following:
characterize “protostellar recycling” of matter into and out of the planet forming disk, in order to constrain and quantify the accretion delivering mass to the central star, the timescale for stellar mass assembly and the available mass for planet formation in the disk
determine the nature of accretion through modeling of angular momentum extraction by disk winds and of star-disk interaction processes
assess the balance of the processes in the late phases of disk dispersal, in particular low accretion vs. photoevaporation and chromospheric emission from the central star.
