18 Apr 2015 | Abstract: | Relations between star formation rates along the spiral arms and the
velocities of gas inflow into the arms in grand-design galaxy NGC 628 were
studied. We found that the radial distribution of average star formation rate
in individual star formation regions in regular spiral arms correlates with the
velocity of gas inflow into the spiral arms. Both distributions have maxima at
a galactocentric distance of 4.5-5 kpc. There are no correlations between the
radial distributions of average star formation rate in star formation regions
in spiral arms and outside spiral arms in the main disc. We also did not find a
correlation between the radial distribution of average star formation rate in
star formation regions in spiral arms and HI column density. | Source: | arXiv, 1504.4743 | Services: | Forum | Review | PDF | Favorites |
