  • We investigate the scatter in the fundamental plane (FP) of early-type galaxies (ETGs) and its dependence on age and internal structure of ETGs, using 16, 283 ETGs with Mr ≤ −19.5 and 0.025 ≤ z < 0.055 in Sloan Digital Sky Survey data. We use the relation between the age of ETGs and photometric parameters such as color, absolute magnitude, and central velocity dispersion of ETGs and find that the scatter in the FP depends on age. The FP of old ETGs with age & 9 Gyrs has a smaller scatter of ∼ 0… CONTINUE READING
