Jets from Young Stars II: Clues from High Angular Resolution Observations

Francesca Bacciotti, Emma Whelan, Leonardo Testi9783540680314, 3540680314, 3540680322

This volume contains the edited lecture notes of the Second JETSET School on Jets from Young Stars: Clues from High Angular Resolution Observations organised by the Marie Curie Research Training Network JETSET: Jet Simulations, Experiments and Theory. After the opening two chapters on jet emission, readers can learn the fundamental background of modern high-spatial-resolution techniques, and how such methods have impacted on our understanding of young stars. The lectures provide hands-on insight into Observing from space, e.g. from HST and in the future JWST, and from the ground with adaptive optics, The use of interferometers at millimetre and infrared wavelengths, Spectro-astrometry, Image analysis and spectral diagnostic techniques, High-Angular Resolution studies of the inner regions of circumstellar disks which play a fundamental role in jet launching.The books’ practical approach makes it an outstanding and extremely useful textbook for PhD students and young researchers in astronomy.
