Ancient globular clusters contain multiple stellar populations identified by variations in light element (e.g., C, N, O, Na). Though many scenarios have been suggested to explain this phenomenon, all are faced with challenges when compared with all the observational evidence. In this Letter, we propose a new scenario in which light element variations are determined by nucleosynthesis in accretion discs around black holes. Since the black holes form after a few Myrs, the cluster is expected to…

Nucleosynthesis in advective accretion disc and outflow: possible explanation for overabundances in winds from X-ray binaries
Multiple spectroscopic lines of different elements observed in winds from X-ray binaries (XRBs), based on one zone model, indicate super-solar abundance of elements, e.g. Mg, Si, S, Ar, Ca, Cr, Mn,
Light element discontinuities suggest an early termination of star formation in the globular cluster NGC 6402 (M14)
NGC 6402 is among the most massive globular clusters in the Galaxy, but little is known about its detailed chemical composition. Therefore, we obtained radial velocities and/or chemical abundances
Linking globular cluster structural parameters and their evolution: multiple stellar populations
Globular clusters (GCs) are known to host multiple stellar populations showing chemical anomalies in the content of elements lighter than Si. The origin of such anomalies and of the internal
Leveraging HST with MUSE: II. Na-abundance variations in intermediate age star clusters
Ancient ($>$10 Gyr) globular clusters (GCs) show chemical abundance variations in the form of patterns among certain elements, e.g. N correlates with Na and anti-correlates with O. Recently, N
The search for multiple populations in Magellanic Clouds clusters – V. Correlation between cluster age and abundance spreads
In our HST photometric survey, we have been searching for multiple stellar populations (MPs) in Magellanic Clouds (MCs) massive star clusters which span a significant range of ages (∼1.5–11 Gyr).
On the role of Type Ia supernovae in the second-generation star formation in globular clusters
By means of 3D hydrodynamic simulations, we study how Type Ia supernovae (SNe) explosions affect the star formation history and the chemical properties of second-generation (SG) stars in globular
Finding black holes with black boxes – using machine learning to identify globular clusters with black hole subsystems
This paper applies machine learning to more than a thousand globular cluster (GC) models simulated with the mocca-Survey Database I project in order to correlate present-day observable properties with the presence of a subsystem of stellar mass black holes (BHs).
Spatial mixing of binary stars in multiple-population globular clusters
We present the results of a study aimed at investigating the effects of dynamical evolution on the spatial distribution and mixing of primordial binary stars in multiple-population globular clusters.
Dynamical evolution of multiple-population globular clusters
We have carried out a set of Monte Carlo simulations to study a number of fundamental aspects of the dynamical evolution of multiple stellar populations in globular clusters with different initial


Nucleosynthesis in Accretion and Outflow Regions around Black Holes
Nucleosynthesis could take place in the hot regions of accretion and outflow around a black hole. We here investigate possible composition changes due to nuclear reaction processes in an accretion
A black hole in a globular cluster
The X-ray signature of an accreting black hole in a globular cluster associated with the giant elliptical galaxy NGC 4472 (in the Virgo cluster) is reported, which rules out any object other than a black Hole in such an old stellar population.
Two stellar-mass black holes in the globular cluster M22
The identification of two black holes in one cluster shows that ejection of black holes is not as efficient as predicted by most models, and it is argued that M22 may contain a total population of ∼5–100 black holes, which could arise from heating produced by the black holes.
Gas depletion in primordial globular clusters due to accretion on to stellar-mass black holes
We consider the effect of compact stellar remnants on the interstellar medium of a massive star cluster following the initial burst of star formation. We argue that accretion onto stellar-mass black
Early disc accretion as the origin of abundance anomalies in globular clusters
Globular clusters (GCs), once thought to be well approximated as simple stellar populations (i.e. all stars having the same age and chemical abundance), are now known to host a variety of anomalies,
A detached stellar-mass black hole candidate in the globular cluster NGC 3201
As part of our massive spectroscopic survey of 25 Galactic globular clusters with MUSE, we performed multiple epoch observations of NGC 3201 with the aim of constraining the binary fraction. In this
Multiple Stellar Populations in Globular Clusters
Globular clusters (GCs) exhibit star-to-star variations in specific elements (e.g., He, C, N, O, Na, Al) that bear the hallmark of high-temperature H-burning. These abundance variations can be
Massive binaries as the source of abundance anomalies in globular clusters
Abundance anomalies observed in globular cluster stars indicate pollution with material processed by hydrogen burning. Two main sources have been suggested: asymptotic giant branch (AGB) stars and
On the Birth Masses of the Ancient Globular Clusters
All globular clusters (GCs) studied to date show evidence for internal (star-to-star) variation in their light-element abundances (including Li, C, N, O, F, Na, Mg, Al, and probably He). These
Supermassive stars as a source of abundance anomalies of proton-capture elements in globular clusters
We propose that the abundance anomalies of proton-capture elements in globular clusters, such as the C-N, Na-O, Mg-Al and Na-F anti-correlations, were produced by super-massive stars with M ~ 10,000
