The international Colloquium “Open Issues in Local Star Formation
and Early Stellar Evolution” was held in Ouro Preto (Brazil) from April
05 to 10, 2003. The Colloquium took place in the “Parque Metal´urgico”,
an old iron industry that has been transformed into a nice modern conference
center. Ouro Preto is a 18th century colonial city that has been
declared a Cultural Heritage of Mankind in 1980. It is situated in the
hills of the State of Minas Gerais at about 100 km from Belo Horizonte....
The study of the formation and early evolution of stars has been an ever
growing part of astrophysical research. Traditionally, often in the shadow of
its big brothers (i.e., the study of stellar structure, stellar atmospheres and
the structure of galaxies), it has become evident that early stellar evolution
research contributes essentially to these classical fields. There are a few new
items on the list of traditional astrophysical studies, some of which are more
related to features known from the extreme late stages of stellar evolution.
In our quest to elucidate the origin of the universe and the formation of
galaxies, particularly that of the Milky Way in which we live, astounding
progress has been made in recent years through observational and theoretical
studies. Not only have gigantic surveys covering a large fraction of the sky
brought statistics enlightening evolutionary paths of galaxies, but powerful
instruments, such as radio interferometers and ground- and space-based optical/
infrared telescopes, have been able to map individual objects with high
sensitivity and spatial resolution.
If a football star touts a deodorant soap, an actress starts everyday with brand. A coffee, a
tennis pro get stamina from Brand X cereal and if a talk show host drives a certain car it does not

pretend to drive a car, it does not mean that your going to go buy one.

An extrasolar planet or exoplanet is a planet orbiting a star (or remnant of a
star) beyond our Solar System. As of autumn 2007, about 250 exoplanets had been
discovered around 220 different stars, including nearly two dozen multiple planet
systems. No less than five exoplanets have been discovered orbiting the star 55
Cancri; one of the planets has nearly four times the mass of Jupiter, another is
comparable with Jupiter in mass, two are slightly less massive than Saturn, while
the innermost planet has a mass similar to that of Uranus....

A few are found alone, but almost all are grouped in formations termed galactic clusters. These formations should not be confused with stellar clusters, globular clusters of stars that exist within a galaxy.
