Ne II fine-structure line emission from the outflows of young stellar objects.


Abstract (from CDS):

The flux and line shape of the fine-structure transitions of Ne II and Ne III at 12.8 and 15.55 µm and of the forbidden transitions of O I λ6300 are calculated for young stellar objects with a range of mass-loss rates and X-ray luminosities using the X-wind model of jets and the associated wide-angle winds. For moderate and high accretion rates, the calculated Ne II line luminosity is comparable to or much larger than produced in X-ray irradiated disk models. All of the line luminosities correlate well with the main parameter in the X-wind model, the mass-loss rate, and also with the assumed X-ray luminosity–and with one another. The line shapes of an approaching jet are broad and have strong blue-shifted peaks near the effective terminal velocity of the jet. They serve as a characteristic and testable aspect of jet production of the neon fine-structure lines and the O I forbidden transitions.
