Outflows and bubbles in Taurus star-formation feedback sufficient to maintain turbulence. (2015)

Keywords : ISM bubbles; ISM: individual: Taurus; ISM: jets and outflows; ISM: kinematics and dynamics; surveys; turbulence

Abstract:We have identified outflows and bubbles in the Taurus molecular cloud based on the ~100deg^2^ Five College Radio Astronomy Observatory ^12^CO(1-0) and ^13^CO(1-0) maps and the Spitzer young stellar object catalogs. In the main 44deg^2^ area of Taurus, we found 55 outflows, of which 31 were previously unknown. We also found 37 bubbles in the entire 100deg^2^ area of Taurus, none of which had been found previously. The total kinetic energy of the identified outflows is estimated to be ~3.9x10^45^erg, which is 1% of the cloud turbulent energy. The total kinetic energy of the detected bubbles is estimated to be ~9.2x10^46^erg, which is 29% of the turbulent energy of Taurus. The energy injection rate from the outflows is ~1.3x10^33^erg/s, which ...(more)

In our study, we used the ^12^CO(1-0) and ^13^CO(1-0) data observed with the 13.7m FCRAO telescope. The FCRAO CO survey was taken between 2003 and 2005. The FWHM beam width is 45" for ^12^CO and 47" for ^13^CO. The MIPS maps were created as part of the final products from the Spitzer Legacy Taurus I and II surveys (Padgett et al. 2007AAS...211.1206P). The data were obtained in fast scan mode in three bands, 24, 70, and 160um, over an area of 44deg^2^. The observations were performed in three epochs between 2005 and 2007, with integration times of 30s (24um) and 15s (70 and 160um). We also adopted the up-to-date catalog of Spitzer YSOs where 215 YSOs and 140 new YSO candidates in Taurus are reported (Rebull et al. 2010, J/ApJS/186/259).
