Akari, SCUBA2 and Herschel data of pre-stellar cores

TL;DR

This paper combines data from Akari, Herschel, and SCUBA2 to study pre-stellar cores in molecular clouds, revealing external heating effects, environmental influences on core evolution, and the role of magnetic fields in filamentary cloud structures.

Contribution

It provides multi-wavelength observational analysis of pre-stellar cores, highlighting external heating, environmental impacts, and magnetic field effects in different molecular cloud regions.

Findings

Cores in Cepheus are externally heated as indicated by Akari data.

Environmental factors influence core evolution in Ophiuchus.

Magnetic fields support filamentary core formation in Lupus I.

Abstract

We show Akari data, Herschel data and data from the SCUBA2 camera on JCMT, of molecular clouds. We focus on pre-stellar cores within the clouds. We present Akari data of the L1147-1157 ring in Cepheus and show how the data indicate that the cores are being externally heated. We present SCUBA2 and Herschel data of the Ophiuchus region and show how the environment is also affecting core evolution in this region. We discuss the effects of the magnetic field in the Lupus I region, and how this lends support to a model for the formation and evolution of cores in filamentary molecular clouds.
