The devil is in the tails: the role of globular cluster mass evolution on stream properties [PDF]
, 2017 We present a study of the effects of collisional dynamics on the formation and detectability of cold tidal streams. A semi-analytical model for the evolution of the stellar mass function was implemented and coupled to a fast stellar stream simulation ...

Gaia EDR3 view on galactic globular clusters [PDF]
Monthly notices of the Royal Astronomical Society, 2021 We use the data from Gaia Early Data Release 3 (EDR3) to study the kinematic properties of Milky Way globular clusters. We measure the mean parallaxes and proper motions (PM) for 170 clusters, determine the PM dispersion profiles for more than 100 ...

Modelling Individual Globular Clusters [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractAstronomers have constructed models of globular clusters for over 100 years. These models mainly fall into two categories: (i) static models, such as King's model and its variants, and (ii) evolutionary models. Most attention has been given to static models, which are used to estimate mass-to-light ratios and mass segregation, and to combine ...

THE ABUNDANCES IN THE STELLAR ATMOSPHERES IN THE M13 GLOBULAR CLUSTER
Odessa Astronomical Publications, 2017 The chemical composition of 5 stars' atmospheres in globular cluster M13 and 2 halo stars taken from literature have been computed. A slight excess of O and deficit of Mg have been defined for globular cluster stars.

The WAGGS project - I. The WiFeS Atlas of Galactic Globular cluster Spectra [PDF]
, 2017 We present the WiFeS Atlas of Galactic Globular cluster Spectra, a library of integrated spectra of Milky Way and Local Group globular clusters. We used the WiFeS integral field spectrograph on the Australian National University 2.3 m telescope to ...

Constraining Co-Varying Coupling Constants from Globular Cluster Age
Universe, 2023 Equations governing the evolution of a star involve multiple coupling constants. Thus, the time it spends as a main-sequence star can be expected to depend on whether or not such constants vary over the time scale of stellar evolution.

MUSE crowded field 3D spectroscopy of over 12 000 stars in the globular cluster NGC 6397 - I. The first comprehensive HRD of a globular cluster [PDF]
, 2016 Aims. We demonstrate the high multiplex advantage of crowded field 3D spectroscopy with the new integral field spectrograph MUSE by means of a spectroscopic analysis of more than 12 000 individual stars in the globular cluster NGC 6397. Methods.
