In the Orion B region, we confirm the existence of a transition in prestellar core formation efficiency (CFE) around a fiducial value A V bg ~ 7 mag in background visual extinction, which is similar to the trend observed with Herschel in other regions, such as the Aquila cloud. The prestellar core mass function (CMF) derived for the whole sample of prestellar cores peaks at ~0.5 M ⊙ (in d N/dlog M format) and is consistent with a power-law with logarithmic slope −1.27 ± 0.24 at the high-mass end, compared to the Salpeter slope of − 1.35. The typical lifetime of the prestellar cores was estimated to be t pre OrionB = 1.7 −0.6 +0.8Myr. A total of 76 protostellar dense cores were also found. In the filamentary subregions NGC 20, NGC 20, and L1622, a total of 1768 starless dense cores were identified based on Herschel data, 490–804 (~28−45%) of which are self-gravitating prestellar cores that will likely form stars in the future. We release new high-resolution maps of column density and dust temperature for the whole complex, derived in the same consistent manner as for other HGBS regions. We present a detailed study of the Orion B molecular cloud complex ( d ~ 400 pc), which was imaged with the PACS and SPIRE photometric cameras at wavelengths from 70 to 500 μm as part of the Herschel Gould Belt survey (HGBS).
