Jets and molecular outflows are ubiquitous phenomena associated with the formation of young stellar objects (YSOs). They play a crucial role in removing angular momentum from the accreting system and in regulating star-formation efficiency. Theoretical studies and observations with ALMA and VLA have shown that jets and winds may have a crucial role in promoting dust growth in the envelope-disc system and in shaping the physical and chemical properties of the surrounding environment. Despite these significant progresses, many fundamental questions remain unanswered regarding the acceleration, collimation, and chemical impact of jets and outflows from YSOs.
From its first light in the AA* configuration, SKA-Mid will overcome the limitations of current mm/cm-facilities by enabling high-angular resolution and high-sensitivity cm-observations, crucial for probing jets and outflows near YSOs. Radio recombination lines offer a unique opportunity to study the 3D-kinematics of jets. Non-thermal linearly polarized synchrotron emission will allow measuring magnetic field strength and morphology at unprecedented scales of a few au, enabling us to test MHD models for wind’s acceleration. Simultaneously, observations of dust thermal emission in outflow cavities will allow studying how dust grows and is eventually transported from the disk to the envelope and back, providing a possible solution to the long-standing challenge of dust growth in discs. Finally, the SKA-project will allow exploring the dust composition and chemical enrichment in shocks, where sputtering and shattering of grains cause the release of their mantles and refractory cores in the gas-phase. Complementary to ALMA's detection of simple and complex organic molecules at mm-wavelengths, the SKA-project will probe for the first time heavy species and give insight into the refractory material of dust grains. Molecules such as long carbon chains/rings, several S-, Al-, Mg-, and other metal-bearing species are expected to have their peak emission at frequencies covered by SKA-Mid but are missed by sub-mm facilities.
In the context of the Cradle-of-Life, this talk will discuss the revolution that SKA-Mid will enable in the study of jets and outflows from YSOs leading to a deeper understanding of the star-formation process and the evolution of the ISM in our Galaxy.
