Subject: [All] HOY 18/12 - 11h: Seminario FCAG: Stellar populations in
nearby galaxies - Dr. Luis Fernando Lomelí Núnez (Observatorio do Valongo,
UFJR, Brasil)

Buenos días,
les recordamos que en el día de hoy, a las 11h en el Salón Meridiano, se
llevará a cabo la charla en el marco de los Seminarios FCAG: *Stellar
populations in nearby galaxies*. La misma estará a cargo del *Dr. Luis
Fernando Lomelí Núnez (Observatorio do Valongo, UFJR, Brasil)*, invitado
del Grupo ALAS. A continuación, les enviamos el resumen y los datos de
conexión para aquellos que no puedan acercarse al Salón Meridiano.

* Resumen: The stellar clusters are one the most visible characteristics in
galaxies. Studies have found that late-galaxies show a two distinct
populations of stellar clusters (e.g. Simanton et al. 2015a), a component
older (globular clusters) and other younger (open clusters). Studying the
different populations of star clusters in galaxies can give us clues about
the evolution and current state of galaxies (Pérez et al. 2013). In the
framework of the hierarchical model of galaxy formation, the current state
of galaxies is preceded by a great history of interactions and mergers of
smaller elements. A consequence of this model of galaxy formation is a
continuous formation of stars, therefore stellar clusters of all ages in
galaxies should be observed. However the detection and study of the stellar
clusters is observational it has focused in old clusters (e.g., Zepf &
Ashman 1993, Ashman & Zepf 1998, Brodie & Strader 2006 and references in)
and in young clusters (e.g, Larsen & Richtler 1999, Bica et al. 2003). On
the other hand, in recent years with the help of the HST, works about a new
star clusters class has been done (e.g., Whitmore et al. 1999 (Antennae),
Mayya et al. 2008 (M82), Santiago-Cortés et al. 2010 (M81) ) such works
have studied a new class of stellar clusters: super stellar clusters (SSC).
They have characteristics similar to the globular clusters (mass,
compactibility, etc.), being the main candidates to be an evolutionary
state previous to the GCs as such, therefore to be intermediate age
clusters. In this seminar we will talk about the properties of the
different stellar clusters. *
