14.4 Stellar evolution in globular clusters - the age of the Galaxy One of the most
difficult problems in observational astronomy is the determination of the distances
of stars (see Appendix Al ), and for this reason star clusters are of special
importance in testing the theory of stellar evolution because all the stars can be
assumed to be at the same distance. It can also be assumed that all the stars in a
cluster formed at more or less the same time in the distant past from material of
the same ...

Our purpose was to study the star formation history in this region and to look for
evidence of large-scale self-propagating star formation. On the basis of an HI
survey, together with the observations of the brightest stars in the Lucke fe Hodge
clusters, Dopita et al. (1985) suggested that the supershell LMC4 is the result of a
self propagating star formation process that have begun some 15 Myr ago. This
scenario implies an age for NGC 1948 of 4 Myr, but the picture proposed by
Dopita et ...

The field is larger in denser regions of the interstellar medium. Cosmic rays are ...
It is of interest to note that the energy densities of photons, magnetic field, cosmic-
ray particles and random motions of the interstellar medium are similar, and are
of the order of 1 eV cm-3 in the vicinity of the Sun. In the cold ... 1.2.1 Generalities
A stellar population can be defined as an ensemble of stars sharing the same
age, the same chemical composition and the same average kinematic properties.
