The dance of stars

The study of dense stellar systems has constantly been an active area of research since half a century. Such systems, which mainly refer to young massive star clusters, globular clusters and dwarf galaxies, play the role of building blocks of the structures in the Universe. This is why it is crucial to understand them. Dense systems of stars present enough challenges to basically all schools in astronomy and in all wavelengths. Young systems challenge an optical/infrared observer to extract the stellar ingredient, their motions and distributions by overcoming the dense crowding of stars. Older systems puzzle one with large over-populations of exotic objects of a wide variety – millisecond radio pulsars, “blue-straggler” stars and X-ray binaries. Continua a leggere The dance of stars
