A closer look at the binary content of NGC 1850
S. Saracino, S. Kamann, N. Bastian +7
Studies of young clusters have shown that a large fraction of O-/early B-type stars are in binary systems, where the binary fraction increases with mass. These massive stars are pr…
The young massive SMC cluster NGC 330 seen by MUSE III. Stellar parameters and rotational velocities
J. Bodensteiner, H. Sana, P. L. Dufton +11
The origin of initial rotation rates of stars, and how a star's surface rotational velocity changes during the evolution, either by internal angular momentum transport or due to in…
Multimass modelling of Milky Way globular clusters -- II. present-day black hole populations
Nolan Dickson, Peter J. Smith, Vincent Hénault-Brunet +2
Populations of stellar-mass black holes (BHs) in globular clusters (GCs) influence their dynamical evolution and have important implications on one of the main formation channels f…
The VLT-FLAMES Tarantula Survey: Observational evidence for two distinct populations of massive runaway stars in 30 Doradus
H. Sana, O. H. Ramírez-Agudelo, V. Hénault-Brunet +17
Two main scenarios have been proposed for origin of massive runaway stars -- dynamical ejection or release from a binary at the first core collapse -- but their relative contributi…
A black hole detected in the young massive LMC cluster NGC 1850
S. Saracino, S. Kamann, M. G. Guarcello +8
We report the detection of a black hole (NGC 1850 BH1) in the 100 Myr-old massive cluster NGC~1850 in the Large Magellanic Cloud. It is in a binary system with a main-sequenc…
Astronomy in a Low-Carbon Future
Christopher D. Matzner, Nicolas B. Cowan, René Doyon +12
The global climate crisis poses new risks to humanity, and with them, new challenges to the practices of professional astronomy. Avoiding the more catastrophic consequences of glob…
On the black hole content and initial mass function of 47 Tuc
Vincent Hénault-Brunet, Mark Gieles, Jay Strader +3
The globular cluster (GC) 47 Tuc has recently been proposed to host an intermediate-mass black hole (IMBH) or a population of stellar-mass black holes (BHs). To shed light on its d…
The Detailed Science Case for the Maunakea Spectroscopic Explorer, 2019 edition
The MSE Science Team, Carine Babusiaux, Maria Bergemann +258
(Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unvei…
Mass modelling globular clusters in the Gaia era: a method comparison using mock data from an -body simulation of M4
Vincent Hénault-Brunet, Mark Gieles, Antonio Sollima +5
As we enter a golden age for studies of internal kinematics and dynamics of Galactic globular clusters (GCs), it is timely to assess the performance of modelling techniques in reco…
Linking the rotation of a cluster to the spins of its stars: The kinematics of NGC6791 and NGC6819 in 3D
Sebastian Kamann, Nate Bastian, Mark Gieles +2
The physics governing the formation of star clusters is still not entirely understood. One open question concerns the amount of angular momentum that newly formed clusters possess…
Radial anisotropy in omega Cen limiting the room for an intermediate-mass black hole
Alice Zocchi, Mark Gieles, Vincent Hénault-Brunet
Finding an intermediate-mass black hole (IMBH) in a globular cluster (or proving its absence) would provide valuable insights into our understanding of galaxy formation and evoluti…
Testing lowered isothermal models with direct N-body simulations of globular clusters - II: Multimass models
Miklos Peuten, Alice Zocchi, Mark Gieles +1
Lowered isothermal models, such as the multimass Michie-King models, have been successful in describing observational data of globular clusters. In this study we assess whether suc…
Testing lowered isothermal models with direct N-body simulations of globular clusters
Alice Zocchi, Mark Gieles, Vincent Hénault-Brunet +1
Several self-consistent models have been proposed, aiming at describing the phase space distribution of stars in globular clusters. This study explores the ability of the recently…
No evidence for younger stellar generations within the intermediate age massive clusters NGC 1783, NGC 1696 and NGC 411
I. Cabrera-Ziri, F. Niederhofer, N. Bastian +11
Recently, Li et al. (2016) claimed to have found evidence for multiple generations of stars in the intermediate age clusters NGC 1783, NGC 1696 and NGC 411 in the Large and Small M…
Biases in the determination of dynamical parameters of star clusters: today and in the Gaia era
A. Sollima, H. Baumgardt, A. Zocchi +4
The structural and dynamical properties of star clusters are generally derived by means of the comparison between steady-state analytic models and the available observables. With t…
Multiple populations in globular clusters: the distinct kinematic imprints of different formation scenarios
Vincent Hénault-Brunet, Mark Gieles, Oscar Agertz +1
Several scenarios have been proposed to explain the presence of multiple stellar populations in globular clusters. Many of them invoke multiple generations of stars to explain the…
Binary-corrected velocity dispersions from single- and multi-epoch radial velocities: massive stars in R136 as a test case
Michiel Cottaar, Vincent Hénault-Brunet
Orbital motions from binary stars can broaden the observed line-of-sight velocity distribution of a stellar system, artificially inflating the measured line-of-sight velocity dispe…
