ALMA detections of circumstellar disks in the giant Hii region M17. Probing the intermediate- to high-mass pre-main-sequence population

J. Poorta, M. Hogerheijde, A. de Koter +8

Our current understanding is that intermediate- to high-mass stars form in a way similar to low-mass stars, that is, through disk accretion. However, the physical conditions that p…

Properties of intermediate- to high-mass stars in the young cluster M17 -- Characterizing the (pre-)zero-age main sequence

Frank Backs, S. A. Brands, M. C. Ramírez-Tannus +5

The outcome of the formation of massive stars is an important anchor point in their evolution. It provides insight into the physics of the assembly process, and sets the conditions…

The spectroscopic binary fraction of the young stellar cluster M17

M. C. Ramírez-Tannus, A. R. Derkink, F. Backs +5

Significant progress has been made toward understanding the formation of massive (M) binaries in close orbits. For example, the detection of a very low velocity d…

Spectroscopic variability of massive pre-main-sequence stars in M17

A. R. Derkink, M. C. Ramírez-Tannus, L. Kaper +4

It is a challenge to study the formation process of massive stars: their formation time is short, they are few, often deeply embedded, and at relatively large distances. Our strate…

Massive pre-main-sequence stars in M17: and overtone CO bandhead emission and the thermal infrared

J. Poorta, M. C. Ramírez-Tannus, A. de Koter +4

Recently much progress has been made in probing the embedded stages of massive star formation, pointing to formation scenarios akin to a scaled up version of low-mass star formatio…

Massive pre-main-sequence stars in M17 -- Modelling hydrogen and dust in MYSO disks

Frank Backs, J. Poorta, Ch. Rab +5

The young massive-star-forming region M17 contains optically visible massive pre-main-sequence stars that are surrounded by circumstellar disks. Such disks are expected to disappea…

A relation between the radial velocity dispersion of young clusters and their age: Evidence for hardening as the formation scenario of massive close binaries

M. C. Ramírez-Tannus, F. Backs, A. de Koter +8

The majority of massive stars ( ) in OB associations are found in close binary systems. Nonetheless, the formation mechanism of these close massive binaries is…

The young stellar content of the giant HII regions M8, G333.6-0.2, and NGC6357 with VLT/KMOS

M. C. Ramírez-Tannus, J. Poorta, A. Bik +14

Context: The identification and characterisation of populations of young massive stars in (giant) HII regions provides important constraints on i) the formation process of massive…
