| Abstract: |
We studied the young star clusters and the star-forming regions in M31, with Galaxy Evolution Explorer (GALEX)
imaging far-UV and near-UV.
The GALEX imaging, combining deep sensitivity and entire coverage of the galaxy, provides a complete picture of
the recent star formation in M31 and its variation with environment throughout the galaxy.
The young star clusters distribution exhibits a distinct peak in the M31 disk around 10 - 12 kpc form the center
and follow a spatial distribution similar to other tracers of disk structure.
On the contrary, star-forming regions show two distinct peaks.
We compared various properties (e.g., age, mass, spatial distribution) of young clusters and star-forming regions.
The young clusters and massive star-forming regions might be associated with the well-known 10 kpc star formation
ring structure.
We suggest the occurrence of a significant recent star formation in the disk of M31. |
