The Evolution of Stellar Exponential Discs

  title={The Evolution of Stellar Exponential Discs},
  author={Annette M. N. Ferguson and Cathie J. Clarke},
Models of disc galaxies which invoke viscosity-driven radial flows have long been known to provide a natural explanation for the origin of stellar exponential discs, under the assumption that the star formation and viscous timescales are comparable. We present models which invoke simultaneous star formation, viscous redistribution of gas and cosmologically-motivated gaseous infall and explore the predictions such models make for the scale length evolution and radial star formation history of… CONTINUE READING
