“…For comparison, the locations of the (sub)mm continuum prestellar cores identified by Motte et al (1998Motte et al ( , 2001 in ρ Oph and NGC2068/2071, respectively, are shown, along with the dust extinction cores of the Pipe nebula (Alves et al 2007, Lada et al 2008, and the correlation observed for diffuse CO clumps (shaded band -cf. Elmegreen & Falgarone 1996). The two solid lines (MBE ∝ RBE ) mark the loci of critically self-gravitating isothermal Bonnor-Ebert spheres at T = 7 K and T = 20 K, respectively.…”

Abstract. We briefly review ground-based (sub)millimeter dust continuum observations of the prestellar core mass function (CMF) and its connection to the stellar initial mass function (IMF). We also summarize the first results obtained on this topic from the Herschel Gould Belt survey, one of the largest key projects with the Herschel Space Observatory. Our early findings with Herschel confirm the existence of a close relationship between the CMF and the IMF. Furthermore, they suggest a scenario according to which the formation of prestellar cores occurs in two main steps: 1) complex networks of long, thin filaments form first, probably as a result of interstellar MHD turbulence; 2) the densest filaments then fragment and develop prestellar cores via gravitational instability.

“…The difference presumably arises because CO clumps are primarily structured by supersonic turbulence (e.g. Elmegreen & Falgarone 1996) while prestellar condensations are largely free of supersonic turbulence and clearly shaped by self-gravity (e.g. Motte et al 2001.…”

“…The grey band shown in Figure 3.8 indicates the behaviour expected for transient, gravitationally unbound CO clumps (Larson 1981;Elmegreen & Falgarone 1996). (Könyves et al 2010;Kirk et al 2013), indicating that prestellar and unbound starless cores are all part of the same population.…”
