Abstract:
We have extracted point-spread-function-fitted stellar photometry from
near-ultraviolet, optical, and near-infrared images, obtained with the
Hubble Space Telescope, of the nearby (D∼5.5Mpc) SBm galaxy NGC 1311.
The ultraviolet and optical data reveal a population of hot
main-sequence (MS) stars with ages of 2-10Myr. We also find
populations of blue supergiants with ages between 10 and 40Myr and
red supergiants with ages between 10 and 100Myr.
Description:
The data for this study are a set of UV, optical, and NIR images
obtained with the Wide-Field and Planetary Camera 2 (WFPC2) and NICMOS
on board HST. We have WFPC2 images taken through the F300W, F606W, and
F814W filters, and a NICMOS image taken with the NIC3 camera through
the F160W filter.
