We review progress over the past decade in observations of large-scale star formation, with
a focus on the interface between extragalactic and Galactic studies. Methods of measuring …

Abstract The James Webb Space Telescope (JWST) is a large (6.6 m), cold (< 50 K), infrared
(IR)-optimized space observatory that will be launched early in the next decade into orbit …

We present and discuss the results of the Herschel Gould Belt survey (HGBS) observations
in an~ 11 deg 2 area of the Aquila molecular cloud complex at d~ 260 pc, imaged with the …

Our Sun and planetary system were born about 4.5 billion years ago. How did this happen,
and what is the nature of our heritage from these early times? This review tries to address …

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 …

Aims. To study the structure of nearby (< 500 pc) dense starless and star-forming cores with
the particular goal to identify and understand evolutionary trends in core properties, and to …

We present key results from the Herschel Orion Protostar Survey: spectral energy
distributions (SEDs) and model fits of 330 young stellar objects, predominantly protostars, in …

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 …

We present 1D radiative transfer modelling of the envelopes of a sample of 18 low-mass
protostars and pre-stellar cores with the aim of setting up realistic physical models, for use in …

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 …
