Properties of the Photometric Components of Lenticular Galaxies

Distribution of the triaxiality parameter 𝑇 for the 115 bulges of S0 and early-type galaxies. Values of 𝑇=0 indicate oblate bulges and 𝑇=1 prolate ones. The distributions of T for bulges with 𝑛<2 (dotted line) and 𝑛>2 (dashed line) are shown in (a). (b) shows the 𝑇 distributions for bulges of galaxies with 𝐵/𝑇<0.3 (dotted line) and 𝐵/𝑇>0.3 (dashed line). See [104] for more details.
