“…Most of the knots have an FWHM of approximately 300 to 450 parsecs. Our results agree with the results obtained by Gusev & Park (2003). The median size of the loose clusters in NUV is 469.6 pc and in FUV is 510.1 pc.…”

“…The angular radius in the bar is 35 − 37 (Boroson 1981;Wilke et al 1999). The radius of the star formation ring coincides with that of the molecular gas (H 2 ) ring (at 13.6 kpc) in the galaxy which indicates that star-forming regions are concentrated in the molecular ring of NGC 2336 (Gusev & Park 2003). In this section, we investigate the star formation regions along the co-rotation ring in NGC 2336.…”

We present a far-UV (FUV) and near-UV (NUV) imaging study of recent star formation in the nearby spiral galaxy NGC 2336 using the Ultraviolet Imaging Telescope (UVIT). NGC 2336 is nearly face-on in morphology and has a multi-armed, branching spiral structure which is associated with star forming regions distributed mainly along the spiral arms and the co-rotation ring around the bar. We have identified 72 star forming knots in the disk, of which only two are in the inter-arm regions and 6 in the co-rotation ring. We have tabulated their positions and estimated their luminosities, sizes, star formation rates, colors, ages and masses. The ages and masses of these star forming knots were estimated using the Starburst99 stellar evolutionary synthesis models. The star forming knots have FUV and NUV mean sizes of 485 pc and 408 pc respectively and mean stellar masses of 9.8 ×10 5 M that range from 5.6 ×10 5 to 1.1 ×10 6 M . Their star formation rates vary from 6.9 ×10 −4 to 2.2 ×10 −2 M /yr in NUV and from 4.5 ×10 −4 to 1.8 ×10 −2 M /yr in FUV. The FUV-NUV colour of the knots is found to be bluest in the central region and becomes progressively redder as the radius increases. Our results suggest that star formation in disks with spiral structure is driven by the spiral density wave and is best traced by UV imaging as it encompasses clusters spanning a wide range of star forming ages and stellar masses.

Spectroscopic observations of 63 H ii regions in six spiral galaxies (NGC 628, NGC 783, NGC 2336, NGC 6217, NGC 7331 and NGC 7678) were carried out with the 6‐m telescope (BTA) of Russian Special Astrophysical Observatory with the Spectral Camera attached to the focal reducer SCORPIO in multislit mode with a dispersion of 2.1 Å pixel−1 and a spectral resolution of 10 Å. These observations were used to estimate the oxygen and nitrogen abundances and the electron temperatures in H ii regions through the recent variant of the strong‐line method (NS calibration). The parameters of the radial distribution (the extrapolated central intercept value and the gradient) of the oxygen and nitrogen abundances in the discs of spiral galaxies NGC 628, NGC 783, NGC 2336, NGC 7331 and NGC 7678 have been determined. The abundances in NGC 783, NGC 2336, NGC 6217 and NGC 7678 are measured for the first time. Galaxies from our sample follow well the general trend in the luminosity–central metallicity diagram for spiral and irregular galaxies.

Aims. We present a statistical analysis of different characteristics of ringed spiral galaxies with the aim of assessing the effects of rings on disk galaxy properties. Methods. We built a catalog of ringed galaxies from the Sloan Digital Sky Survey Data Release 14 (SDSS-DR14). Via visual inspection of SDSS images, we classified the face-on spiral galaxies brighter than g < 16.0 mag into galaxies with: an inner ring, an outer ring, a nuclear ring, both an inner and an outer ring, and a pseudo-ring. In addition to rings, we recorded morphological types and the existence of bars, lenses, and galaxy pair companions with or without interaction. With the goal of providing an appropriate quantification of the influence of rings on galaxy properties, we also constructed a suitable control sample of non-ringed galaxies with similar redshift, magnitude, morphology, and local density environment distributions to those of ringed ones. Results. We found 1868 ringed galaxies, accounting for 22% of the full sample of spiral galaxies. In addition, within galaxies with ringed structures, 46% have an inner ring, 10% an outer ring, 20% both an inner and an outer ring, 6% a nuclear ring, and 18% a partial ring. Moreover, 64% of the ringed galaxies present bars. We also found that ringed galaxies have both a lower efficiency of star formation activity and older stellar populations (as derived with the Dn(4000) spectral index) with respect to non-ringed disk objects from the control sample. Moreover, there is a significant excess of ringed galaxies with red colors. These effects are more important for ringed galaxies that have inner rings and bars with respect to their counterparts that have some other types of rings and are non-barred. The color-magnitude and color-color diagrams show that ringed galaxies are mostly concentrated in the red region, while non-ringed spiral objects are more extended to the blue zone. Galaxies with ringed structures present an excess of high metallicity values compared to non-ringed ones, which show a 12 + Log(O/H) distribution toward lower values. These findings seem to indicate that rings are peculiar structures that produce an accelerating galactic evolution, strongly altering the physical properties of their host galaxies.
