Description
Many barred galaxies show a set of symmetric enhancements at the ends of
the stellar bar, called the ansae, or ``handles'', of the bar. In this
poster, we make a quantitative analysis of the occurrence of ansae in
barred galaxies, making use of The de Vaucouleurs Atlas of Galaxies by
Buta and collaborators. We find that ˜40% of SB0s show ansae in
their bars, thus confirming that ansae are common features in barred
lenticulars. The ansae frequency decreases dramatically with later
types, and hardly any ansae are found in galaxies of type Sb or later.
