Abstract: |
In the last decade, we have started to spatially resolve the relatively small gas and dust
condensations in high-mass star-forming regions that will eventually become a massive star
or system. We call these condensations of sizes on the order of 0.01 pc “cores”, and by
estimating their masses we can construct the so-called Core Mass Function (CMF) of a
region, to compare with the IMF and try to determine the evolutionary process from core to
star.
For massive star-forming regions, the relationship between the CMF and the IMF is not yet
well understood. This is, among other factors, due to the fact that there are not many
massive CMF determined. Even then, some of those few CMF seem to tell a story of
evolution, by presenting different slopes than that of the Salpeter IMF while others, seem to
be very similar to the IMF.
In this work we show CMFs obtained for a group of massive star-forming regions with SMA
and PdBI observations. These CMFs show different slopes, and we explain the possible
significance this has on the evolution of the cores. |
