Joseph Armstrong

Postdoc at Astronomy and Plasmaphysics

The majority of stars in our Galaxy and others form in unbound associations or dense clusters, ranging in size from hundreds of stars to tens of thousands. These groups are vital for studying the formation and early evolution of stars and star-forming regions. It is in these early stages of a star's life that their subsequent evolution is determined, and in which they form planetary systems.

Joseph studies the dynamics of young associations and clusters, combining Gaia astrometry with spectroscopic observations, in order to understand their formation and evolution.
