Cold dark clouds are nearby members of the densest and coldest phase in the Galactic
interstellar medium, and represent the most accessible sites where stars like our Sun are …

We have undertaken a survey of N 2 H+ and N 2 D+ toward 31 low-mass starless cores
using the IRAM 30 m telescope. Our main objective has been to determine the abundance …

Context. The thermal structure of a starless core is crucial for our understanding of the
physics in these objects and hence for our understanding of star formation. Theory predicts a …

We present the Planck Catalogue of Galactic Cold Clumps (PGCC), an all-sky catalogue of
Galactic cold clump candidates detected by Planck. This catalogue is the full version of the …

Low-mass dense cores represent the state of molecular gas associated with the earliest
phases of low-mass star formation. Such cores are called" protostellar" or" starless," …

We study the physical processes that affect the alignment of grains subject to radiative
torques (RATs). To describe the action of RATs, we use the analytical model (AMO) of RATs …

Context. The high degree of deuteration observed in some prestellar cores depends on the
ortho-to-para H 2 ratio through the H $ _3^+ $ fractionation. Aims. We want to constrain the …

Context. In the project galactic cold cores we are carrying out Herschel photometric
observations of cold regions of the interstellar clouds as previously identified with the Planck …

Context. Theoretical arguments suggest that dust grains should grow in the dense cold parts
of molecular clouds. Evidence of larger grains has so far been gathered in near/mid infrared …

Grain alignment by radiative torques (RATs) has been extensively studied for various
environment conditions, including interstellar medium, dense molecular clouds and …
