Outflows and bubbles in Taurus: star-formation feedback sufficient to maintain turbulence.

Abstract (from CDS):

We have identified outflows and bubbles in the Taurus molecular cloud based on the ∼100 deg2 Five College Radio Astronomy Observatory 12CO(1-0) and 13CO(1-0) maps and the Spitzer young stellar object catalogs. In the main 44 deg2 area of Taurus, we found 55 outflows, of which 31 were previously unknown. We also found 37 bubbles in the entire 100 deg2 area of Taurus, none of which had been found previously. The total kinetic energy of the identified outflows is estimated to be ∼3.9 x 1045 erg, which is 1% of the cloud turbulent energy. The total kinetic energy of the detected bubbles is estimated to be ∼ 9.2 x 1046 erg, which is 29% of the turbulent energy of Taurus. The energy injection rate from the outflows is ∼1.3 x 1033 erg/s, which is 0.4-2 times the dissipation rate of the cloud turbulence. The energy injection rate from bubbles is ∼ 6.4x1033 erg/s, which is 2-10 times the turbulent dissipation rate of the cloud. The gravitational binding energy of the cloud is ∼1.5 x 1048 erg, that is, 385 and 16 times the energy of outflows and bubbles, respectively. We conclude that neither outflows nor bubbles can provide sufficient energy to balance the overall gravitational binding energy and the turbulent energy of Taurus. However, in the current epoch, stellar feedback is sufficient to maintain the observed turbulence in Taurus.
