Description
We studied the fraction and properties of bars in a sample of about 3000
galaxies extracted from SDSS-DR5. This represents a volume limited
sample with galaxies located between redshift 0.01-20, and inclination i < 60°.
Interacting galaxies were excluded from the sample. The fraction of
barred galaxies in our sample is 45%. We found that 32% of S0s, 55% of
early-type spirals, and 52% of late-type spirals are barred galaxies.
The bars in S0s galaxies are weaker than those in later-type galaxies.
The bar length and galaxy size are correlated, being larger bars located
in larger galaxies. Neither the bar strength nor bar length correlate
with the local galaxy density. On the contrary, the bar properties
correlate with the properties of their host galaxies. Galaxies with
higher central light concentration host less and weaker bars.

Starsbursts play a key role in the cosmic evolution of galaxies, and thus in the star formation (SF) history of the universe, the production of metals, and the feedback coupling galaxies with the cosmic web. Extreme SF conditions prevail early on during the formation of the first stars and galaxies, therefore, the starburst phenomenon constitutes a
