| Abstract: | Jets and winds in pre-main sequence (PMS) stars are often heated and ionized, and understanding their heating mechanism is desired to compare UV-to-IR spectral signatures with models and thus investigate their driving mechanism. We review our results of long-slit spectroscopy and spectro-astrometry for He I 1.083 μm and Hα emission, and investigate the heating mechanisms in the jet in the outer (>10 AU) and inner (<10 AU) regions, respectively. |
