TMC-1C: an accreting starless core
S. Schnee, P. Caselli, A. Goodman +3
We have mapped the starless core TMC-1C in a variety of molecular lines with the IRAM 30m telescope. High density tracers show clear signs of self-absorption and sub-sonic infall a…
Formation and Collapse of Quiescent Cloud Cores Induced by Dynamic Compressions
Gilberto C. Gómez, Enrique Vázquez-Semadeni, Mohsen Shadmehri +1
(Abridged) We present numerical hydrodynamical simulations of the formation, evolution and gravitational collapse of isothermal molecular cloud cores. A compressive wave is set up…
Statistics of Core Lifetimes in Numerical Simulations of Turbulent, Magnetically Supercritical Molecular Clouds
Roberto Galván-Madrid, Enrique Vázquez-Semadeni, Jongsoo Kim +2
We present measurements of the mean dense core lifetimes in numerical simulations of magnetically supercritical, turbulent, isothermal molecular clouds, in order to compare with ob…
