The Initial Mass Function and its Variation

By Eva Grebel, Wolfgang Br and Pavel Kroupa


Abstract. The observed distribution of IMF shapes can be understood as statistical sampling from a universal IMF and variations that result from stellar-dynamical processes. However, young star clusters appear to have an IMF biased towards low-mass stars when compared to the Galactic disk IMF, which comprises an average populated by star-formation episodes occurring Gyrs ago. In addition to this tentative but exciting deduction, this text outlines some of the stumbling blocks hindering the production of rigorous IMF determinations, and discusses the most robust evidence for structure in it. Also, it is stressed that an invariant IMF should not be expected. 1
