According to a study from Yerevan, Armenia, "A statistical study of
the dependence of the star formation rate in the nuclear regions of
39 Kazarian galaxies on the integral parameters of these galaxies
is carried out on the basis of spectra from SDSS DR6. The value of
SFR/kpc(2) for our sample lies in the range 0.013A center dot 2.04M
(aEuro) year(-1)kpc(-2) (with the maximum value of 2.04 corresponding
to the Kaz 98 (merger))."

"It is found that the surface density of the rate of star formation
correlates positively with the bar structure parameter and EW(H alpha),
and that, for spiral galaxies of early morphological types, SFR/kpc(2)
is greater than for the later types. It is shown that the color B-R
for the galaxies and the color (u - g) (nucl) for the nuclear region
correlate positively with the total absorption A(H alpha) in the Ha
line for the nuclear region," wrote V.Z. Adibekyan and colleagues
(see also Astrophysics).

The researchers concluded: "The average value of A(H alpha) for our
samples is found to be A(H alpha)=1.3 +/- 0.09 magnitudes."

Adibekyan and colleagues published their study in Astrophysics (Study
of the dependence of the star formation rate in the nuclear regions
of 39 Kazarian galaxies on their integral parameters. Astrophysics,
2009;52(2):192-204).
