Young and intermediate-age massive star clusters.
An overview of our current understanding of the formation and evolution of star clusters is given, with the main emphasis on high-mass clusters. Clusters form deeply embedded within dense clouds of molecular gas. Left-over gas is cleared within a few million years and, depending on the efficiency of star formation, the clusters may disperse almost immediately or remain gravitationally bound. Cu...
متن کاملthe impact of musical texts on the text recall of young learners of english in isfahan junior high schools
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
15 صفحه اولEmbedded Clusters and the Imf
Despite valiant efforts over nearly five decades, attempts to determine the IMF over a complete mass range for galactic field stars and in open clusters have proved difficult. Infrared imaging observations of extremely young embedded clusters coupled with Monte Carlo modeling of their luminosity functions are improving this situation and providing important new contributions to our fundamental ...
متن کاملThe effects of young embedded groups and clusters on forming solar systems
Most stars—and hence most solar systems—form within groups or clusters. This contribution discusses how these star forming environments affect the planetary systems forming within them. The discussion starts with the dynamical evolution of young stellar clusters with N = 100–1000 members. We use N -body simulations to explore how evolution depends on system size N and the initial conditions. Mo...
متن کاملAutomatically Determining Number of Clusters
Automatically determining number of clusters in the data is an unsolved/unexplored problem. First I'll show why we need to do this, and whether this is a reasonable problem in text clustering in particular. Then starting from simple 1-d/2-d study, I nd BIC (Bayesian Information Criterion) is a useful measure, which by penalizing model tness by model complexity, usually tells the right number of...
