Why do massive stars form bow shocks? Bulk ISM motion as the main driver of bow shock formation and geometry
J. van den Eijnden, L. Kaper
Bow shocks are one the most commonly observed impact sites of massive star feedback. Their existence is often taken as evidence of the supersonic motion or even runaway nature of t…
OB runaway stars originating in the Vel OB1 association
N. Azatyan, L. Kaper, A. Samsonyan +4
OB runaway stars are massive stars moving through interstellar space at high velocities (up to 200 km/s), produced by dynamical ejections in young massive clusters or supernova exp…
The origin of the most recently ejected OB runaway star from the R136 cluster
Simon Portegies Zwart, Michel Stoop, Lex Kaper +3
The solar-mass (\MSun) star-cluster R136 (NGC~2070) in the Tarantula Nebula in the Large Magellanic Cloud is the host of at least 55 massive stars ($M \apgt 10$\,\MS…
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…
