| Abstract: |
We present preliminary results from our HST/WFC3 F469N narrow-band
imaging of the nearby star-forming galaxy M101 in which we search
for Wolf-Rayet (WR) stars, possible progenitors of Type Ibc
core-collapse supernovae (ccSNe). From analysis of the central
pointing of M101 we identify ∼1000 WR candidates from
photometric analysis and estimate ∼ 450 using the “blinking”
method. From analysis of a sample region we find that 35% of our WR
candidates would not be detected in ground-based surveys and 40% of
sources are not detected in the HST F435W images, highlighting the
importance of high spatial resolution narrow-band imaging. |
