SUMMARY:Structural properties of isolated galaxies 
DESCRIPTION:Structural properties of isolated galaxies \nDr. Mirian Fernand
 ez Lorenzo\n\nDifferent components of galaxies are the result of internal 
 and  environmental processes during their lifetimes. Disentangling these  
 processes is an important issue for understanding how galaxies form and  e
 volve. In this context isolated galaxies provide a fruitful sample for  ex
 ploring galaxies which have  evolved mainly by internal processes  (minima
 l merger/accretion/tidal effects). I will present the structural  analysis
  performed as part of the AMIGA (Analysis of the interstellar  Medium of I
 solated GAlaxies; http://www.amiga.iaa.es)  project. The analysis of the s
 tellar mass-size relation of our spiral  galaxies reveals a larger size fo
 r disks in low-density environments, as  well as a dependence of disk size
  on the number of satellites. A 2D  bulge/disk/bar decomposition of SDSS i
 -band images was performed in  order to identify the pseudobulges in our s
 ample. We derived (g-i) bulge  colors and find a large fraction of pseudob
 ulges in the red sequence of  early-type galaxies. The bluer pseudobulges 
 in our sample tend to be  located in those galaxies more affected by tidal
  interactions. The  properties of the majority of bulges in isolated galax
 ies suggest that  pseudobulges formed most of their mass at an early epoch
 , and that  specific environmental events may rejuvenate pseudobulges.
