Abstract

Inhomogenities were found in the distribution of the cold fraction in the interstellar medium (traced by Planck cold clumps). In large scales there is a significant overdensity on some shells, in small scales there are elongated groups. Critical column density for star formation is N(H2) = 7 × 1021 cm−2.
