Ages˛: Taking Stellar Ages to the Next Power
An international astronomical symposium on the ages of stars, to be held in Elba, September 18-22, 2017.
The first "Ages of Stars" meeting was held in Baltimore, Maryland in 2008. Real progress has been made in the field since then, and Ages˛ is an opportunity to review what has been accomplished and where effort is needed. Among the subjects to be discussed are:
- Ages of clusters and age spreads, and ages of small stellar groups
- Ages of pre-main sequence stars
- Ages of the oldest stars and clusters
- Ages of low-mass stars and brown dwarfs
- Ages of evolved stars and applying them to Galactic archaeology
- The current state of stellar models
- Ages of solar-like stars from seismology and implications for gyrochronology
- Star formation histores in the Local Group
Scientists are invited to propose topics and speakers for invited talks. For additional information, please visit STScI or send an email to David Soderblom.
To register for the 2017 Ages Symposium and to find local information, please visit the University of Pisa site.
