Erratum: 'Formation of Massive Molecular Cloud Cores by Cloud-Cloud Collision' (2013, ApJ, 774, L31)

摘要

Equation (2) should have been written as where ceff ~(1/2). Due to this correction, a revised version of Table 1 of the published article is needed. To obtain the revised Table 1, we have reanalyzed simulation data based on Equation (2), and we have fixed a bug of the data analysis code that overestimated the effective Jeans mass. The thermal Jeans mass, the ratios of the Alfvénic and turbulent Jeans masses to the thermal Jeans mass, and the mean magnetic field strengths of the massive core for the fiducial model shown in the last paragraph of Section 3.1 are corrected to be M_(J,therm) = 0.27 M_(Sun), M_(J,Alf)/M_(J,therm) = 291, M_(J,turb)/M_(J,therm) = 152, and ∣_(core)∣ = 321μG, respectively. These corrections do not affect discussions given in the Letter in a qualitative sense.
