B and R CCD images and J NICMOS3 frames taken with the Calar Alto 3.5 m telescope of the dwarf irregular galaxy UGC 685 are presented. The brightest part of the stellar population is resolved in B and R , very few also in J . The stellar color-magnitude diagram is discussed. An estimate of the distance to UGC 685 of 5.5 Mpc is derived based on the brightest blue supergiant stars. Most of the resolved bright stars show colors in the range . The continuum light of the unresolved stars is… Expand

Structure and stellar content of dwarf galaxies - VI. $\vec B$, $\vec V$ and $\vec R$ photometry of northern field dwarf galaxies
CCD photometry in the Cousins B , V and R bands of 19 northern field dwarf galaxies is presented. For each galaxy, and for each colour, we determined total magnitude, effective radius and effectiveExpand
The Evolutionary Status of Isolated Dwarf Irregular Galaxies. I. UBV and Hα Imaging Observations
The results of UBV and Hα imaging of a large sample of gas-rich, isolated, dwarf irregular galaxies are presented. The majority of the low-luminosity systems in this sample have no known neighborsExpand
The Evolutionary Status of Isolated Dwarf Irregular Galaxies. II. Star Formation Histories and Gas Depletion
The results of UBV and Hα imaging of a large sample of isolated dwarf irregular galaxies are interpreted in the context of composite stellar population models. The observed optical colors are bestExpand
THE OUTER DISKS OF DWARF IRREGULAR GALAXIES
In order to explore the properties of extreme outer stellar disks, we obtained ultra-deep V and GALEX ultraviolet (UV) images of four dwarf irregular galaxies and one blue compact dwarf galaxy, andExpand
A Compact Population of Red Giants in the Blue Compact Dwarf Galaxy UGCA 290
We present Hubble Space Telescope/Wide Field Planetary Camera 2 single-star photometry for the blue dwarf galaxy UGCA 290, whose morphology is intermediate between classic iE blue compact dwarfExpand
Surface photometry of nearby field galaxies: the data
We have obtained integrated spectra and multifilter photometry for a representative sample of similar to 200 nearby galaxies. These galaxies span the entire Hubble sequence in morphological type, asExpand
Star Formation Histories of the LEGUS Dwarf Galaxies. III. The Nonbursty Nature of 23 Star-forming Dwarf Galaxies
We derive the recent star formation histories of 23 active dwarf galaxies using HST observations from the Legacy Extragalactic UV Survey (LEGUS). We apply a color-magnitude diagram fitting techniqueExpand
Tip of the Red Giant Branch Distances to NGC 4214, UGC 685, and UGC 5456
We have used WFPC2 VRI observations to calculate the distances to three nearby galaxies, NGC 4214, UGC 685, and UGC 5456, using the tip of the red giant branch method. Our values for NGC 4214 (2.94 ±Expand
