We present a detailed study of the flocculent spiral galaxy NGC 7793 , part of the Sculptor group .
By analyzing the resolved stellar populations of the galaxy , located at a distance of \sim 3.7 Mpc , we infer for the first time its radial star formation history ( SFH ) from Hubble Space Telescope photometry , thanks to both archival and new data from the Legacy ExtraGalactic UV Survey .
We determine an average star formation rate ( SFR ) for the galaxy portion covered by our F555W and F814W data of 0.23 \pm 0.02 \mathrm { M _ { \odot } / yr } over the whole Hubble time , corresponding to a total stellar mass of ( 3.09 \pm 0.33 ) \times 10 ^ { 9 } \mathrm { M _ { \odot } } in agreement with previous determinations .
Thanks to the new data extending to the F336W band , we are able to analyze the youngest stellar populations with a higher time resolution .
Most importantly , we recover the resolved SFH in different radial regions of the galaxy ; this shows an indication of a growing trend of the present-to-past SFR ratio , increasing from internal to more external regions , supporting previous findings of the inside-out growth of the galaxy .
