TL;DR: In this article, the authors derived detailed theoretical models for 1074 nearby stars from the Spectroscopic Properties of Cool Stars (SPOCS) catalog and derived the likelihood for each set of stellar model parameters separated by uniform time steps along the stellar evolutionary tracks.

TL;DR: It is reported that globular clusters can be grouped into a few distinct families on the basis of the radial distribution of blue stragglers, corresponding well to an effective ranking of the dynamical stage reached by stellar systems, thereby permitting a direct measure of the cluster dynamical age purely from observed properties.

TL;DR: In this paper, the angular momentum evolution of very low-mass stars (0.1-0.5 M) was studied and the effect of rotation on the effective temperature and luminosity of these stars was investigated.

TL;DR: It is suggested that the two observed sequences of blue stragglers in M 30 are a consequence of cluster core collapse, with the bluer population arising from direct stellar collisions and the redder one arising from the evolution of close binaries that are probably still experiencing an active phase of mass transfer.

TL;DR: In this paper, the internal kinematics of young star clusters at sub-km/s level were studied, with implications for understanding how star clusters form and evolve, and they used a sample of 28 star clusters and associations with ages from 1-5 Myr.
