Subaru BVI photometry of objects in M33's disk
Listed in IVOA Registry (Virtual Observatory)
We have surveyed the complete extent of the disk of M33 --a gas-rich low-mass dwarf spiral galaxy in the Local Group.
Description
The B-, V-, and I-passband (the Johnson-Cousins system) CCD images (typical seeing ~0.8") were obtained with the Subaru Telescope equipped with the Suprime-Cam mosaic camera. The wide-field (~1.0{deg}x1.5{deg}) catalog of 803,095 (15<=V<=25) starlike objects, measured using the point-spread function and aperture photometry techniques, is presented.
We determined the distance modulus of M33 using the tip of the red giant branch (I_TRGB_=20.64+/-0.02) as a reference point of (m-M)_0_=24.63+/-0.02_stat_+/-0.06_syst_ (843kpc). We found young (<~100Myr) stellar populations residing up to the deprojected radius of ~10kpc. The scale length of the young main-sequence (MS) star surface-number density in the range of radial distances from 7 to 9kpc is 0.53+/-0.03kpc.

The youngest MS stars (<~15Myr) reside up to the radius of ~8kpc. This distribution of stellar populations may suggest an outside-in scenario of recent star formation in the disk of M33.
