Rotation in young massive star clusters [PDF]

Monthly Notices of the Royal Astronomical Society, 2017
Hydrodynamical simulations of turbulent molecular clouds show that star clusters form from the hierarchical merger of several sub-clumps. We run smoothed-particle hydrodynamics simulations of turbulence-supported molecular clouds with mass ranging from 1700 to 43000 Msun. We study the kinematic evolution of the main cluster that forms in each cloud. We

The early evolution of young massive clusters

Astronomy & Astrophysics, 2023
Massive stars are predominantly born in stellar associations or clusters. Their radiation fields, stellar winds, and eventual supernovae have a strong impact on their local surroundings. A significant fraction of massive stars are observed to be so-called runaway stars, which travel through the galaxy at high speed.

GOALS-JWST: Revealing the Buried Star Clusters in the Luminous Infrared Galaxy VV 114

The Astrophysical Journal Letters, 2023
We present the results of a James Webb Space Telescope NIRCam investigation into the young massive star cluster (YMC) population in the luminous infrared galaxy VV 114.

The Mass Function of Super Giant Molecular Complexes and Implications for Forming Young Massive Star Clusters in the Antennae (NGC 4038/39)

, 2003
We have used previously published observations of the CO emission from the Antennae (NGC 4038/39) to study the detailed properties of the super giant molecular complexes with the goal of understanding the formation of young massive star clusters.

On the possible generation of the young massive open clusters Stephenson2 and BDSB122 by Omega Centauri [PDF]

, 2009
A massive objects such as a globular cluster passing through the disk of a galaxy can trigger star formation. We test the hypothesis that the most massive globular cluster in the Galaxy, $\omega$ Centauri, which crossed the disk approximately $24\pm2 ...

JWST/NIRCam Probes Young Star Clusters in the Reionization Era Sunrise Arc

The Astrophysical Journal, 2023
Star cluster formation in the early universe and its contribution to reionization remains largely unconstrained to date. Here we present JWST/NIRCam imaging of the most highly magnified galaxy known at z ∼ 6, the Sunrise arc.

How can young massive clusters reach their present-day sizes?

, 2015
The classic question that how young massive star clusters attain their shapes and sizes, as we find them today, remains to be a challenge. Both observational and computational studies of star-forming massive molecular gas clouds infer that massive ...

New Candidate Massive Clusters from 2MASS [PDF]

, 2013
Massive stars are important for the evolution of the interstellar medium. The detailed study of their properties (such as mass loss, rotation, magnetic fields) is enormously facilitated by samples of these objects in young massive galactic star clusters.

The Impact of Stellar Radiative Feedback on Formation of Young Massive Clusters via Fast H i Gas Collisions

The Astrophysical Journal
Young massive clusters (YMCs) are dense aggregates of young stars and are often speculated as potential precursors to globular clusters. However, the formation mechanism of massive and compact gas clumps that precede YMCs remains unknown.

Photoevaporation and Close Encounters: How the Environment around Cygnus OB2 Affects the Evolution of Protoplanetary Disks

The Astrophysical Journal Supplement Series, 2023
In our Galaxy, star formation occurs in a variety of environments, with a large fraction of stars formed in clusters hosting massive stars. OB stars have an important feedback on the evolution of protoplanetary disks orbiting around nearby young stars ...
