Reverse dynamical evolution of Eta Chamaeleontis [PDF]

, 2013
In the scope of the star formation process, it is unclear how the environment shapes the initial mass function (IMF). While observations of open clusters propose a universal picture for the IMF from the substellar domain up to a few solar masses, the ...
