| Abstract: |
The relationship between star formation rate (SFR) and the interstellar
gas surface density (Σgas) is fundamental to galaxy
evolution. To achieve physical understanding of this relationship, it
is necessary to study the detailed star formation properties of giant
molecular clouds (GMCs). Here we report preliminary results of the
case study of W31 and W43, two obscured starburst regions in the Milky Way.
We have used IR spectroscopic observations to determine the type and
nature of luminous sources in these two regions. Progressions of
massive star formation are seen in both W31 and W43. We will
extend this work to more starbursts associated with GMCs and
aim at assessing the SFR-Σgas relation in the
Galaxy. |
