Context. Understanding the details of the formation process of massive (i.e. M ≳ 8–10 M⊙) stars is a long-standing problem in astrophysics. They form and evolve very quickly, and almost their entire formation process takes place deeply embedded in their parental clumps. Together with the fact that these objects are rare and at a relatively large distance, this makes observing them very challenging. Aims. We present a method for deriving accurate timescales of the evolutionary phases of the high… 


Chemical evolution in the early phases of massive star formation. I
Understanding the chemical evolution of young (high-mass) star-forming regions is a central topic in star formation research. Chemistry is employed as a unique tool 1) to investigate the underlying
The evolution of the spectral energy distribution in massive young stellar objects
Context. The mechanism of formation of massive stars is still a matter of debate. It is not yet clear if it can be considered to be a scaled-up analogue of the low-mass star regime, or if there are
Chemical evolution of star-forming regions.
Recent advances in the understanding of the chemical processes that occur during all stages of the formation of stars, from the collapse of molecular clouds to the assemblage of icy planetesimals in
Global collapse of molecular clouds as a formation mechanism for the most massive stars
The relative importance of primordial molecular cloud fragmentation versus large-scale accretion still remains to be assessed in the context of massive core/star formation. Studying the kinematics of
ATLASGAL-selected massive clumps in the inner Galaxy: V. Temperature structure and evolution
Context: Observational identification of a solid evolutionary sequence for high-mass star-forming regions is still missing. Spectroscopic observations give the opportunity to test possible schemes
ATLASGAL-selected massive clumps in the inner Galaxy, II: Characterisation of different evolutionary stages and their SiO emission
The processes leading to the birth of high-mass stars are poorly understood. We characterise here a sample of 430 massive clumps from the ATLASGAL survey, which are representative of different
Massive molecular outflows
With the aim of understanding the role of massive outflows in high-mass star formation, we mapped in the 12 CO $J=2-1$ transition 26 high-mass star-forming regions at very early stages of their
Massive star formation in 100,000 years from turbulent and pressurized molecular clouds
It is shown that t*f is determined by the conditions in the star's natal cloud, and is typically ∼105 yr, which is sufficient to overcome radiation pressure from ∼100M[circdot] protostars, while simultaneously driving intense bipolar gas outflows.
High-Mass Star and Massive Cluster Formation in the Milky Way
This review examines the state-of-the-art knowledge of high-mass star and massive cluster formation, gained from ambitious observational surveys, which acknowledges the multiscale characteristics of
Toward Understanding Massive Star Formation
AbstractAlthough fundamental for astrophysics, the processes that produce massive stars are not well understood. Large distances, high extinction, and short timescales of critical evolutionary phases
