Nonradial and nonpolytropic astrophysical outflows IX. Modeling T Tauri jets with a low mass-accretion rate
MHD, Stars: pre-main sequence, Stars: winds, outfl ows, Stars: mass-loss, Stars: rotation, ISM
2011/10/8
Context: A large sample of T Tauri stars exhibits optical jets, approximately half of which rotate slowly, only at ten per cent of their breakup velocity. The disk-locking mechanism has been shown to ...

We present herein a theoretical study of correlations between spectral indexes of X-ray emergent spectra and mass accretion rate (m˙ ) in black hole (BH) sources,which provide a definitive signature f...
