“…The "Notes" column present comments on the quality of the data or of the fit to obtain the metallicity breaks (S= strong point, W= Weak point, FP= too few points in the metallicity distribution, see text for explanation of S and W). The last column gives the references for the radial metallicity distributions according to [62], [89], [125], [133], [135] [22], [54], [62], [71], [76], [89], [109], [125], [ [10], [17], [38], [76], [80], [88], [89], [109], [121], [122], [125], [135], [137]…”

We analyzed the relation between the corotation radii and the galactic radii at which breaks or changes of slope of the metallicity gradients occur in spiral galaxies. With this purpose we compiled the results from the literature on rotation curves, corotation radii and radial metallicity distributions of 27 galaxies, of which 16 were considered qualified to be studied in the context of this work. We re-scaled all references of each galaxy to a same framework in order to compare the results and to identify the radii where breaks and changes of slopes are found, when non-linear models fit the radial metallicities better than a linear model. In most galaxies we have found minima and breaks in radial metallicity near the corotation radius, revealing a significant correlation between these two radii, as it occurs in our Galaxy. The results are interpreted as a consequence of long-lived spiral structures, in which the starformation rate depends on the distance to the corotation radius, producing secular effects in the observed radial metallicity distributions.

Hypersonic velocity impact on a-SiC target: A diagram of damage characteristics via molecular dynamics simulations

Dynamic damage response characteristics of an amorphous silicon carbide target due to hypersonic velocity impacts of diamond projectiles are investigated using molecular dynamics simulations. In a certain range of radii of the projectile, four distinct regimes of damage are uncovered and summarized in a penetration depth diagram. The regimes correspond to shallow crater formation, deep penetration into the target, deep penetration with local melting of the target, and complete disintegration of the projectile. In the third regime, a logarithmic dependence of the penetration depth as a function of the projectile velocity has been found and explained by an analytical model.
