Summary of burning questions proposed by the registrants

This is an ordered compilation of the questions raised by the attendees. We have placed them in five working groups according to their topics. The job of the working groups will be to choose and focus on some of these questions during their discussion. Enjoy !

Working group 1: Star formation in various types of environments

- Star formation and dust in young open clusters

- SNe induced star formation

- Features of star formation in low density environments

- Can massive stars be formed away from molecular clouds ?

- All about population III stars

elsewhere ? - Latest news about the UV-upturn phenomenon (UV emission in ellipticals)
