The bends in the slopes of radial abundance gradients in the disks of spiral galaxies - Do they exist?
PILYUGIN L.S.
Abstract (from CDS):
Spiral galaxies with a reported bend in the slope of gradient in the oxygen abundances (O/H)R23, derived with traditionally used R23-method, were examined. It is shown that the artificial origin of the reported bends can be naturally explained. Two situations that result in a false bend in the slope of (O/H)R23 gradient are indicated. It is concluded that at the present time there is no example of a galaxy with an undisputable established bend in the slope of the oxygen abundance gradient.
