Stellar mass distribution of S${}^4$G disk galaxies and signatures of bar-induced secular evolution

Simón Díaz-García, Heikki Salo, Eija Laurikainen

We use 3.6 $\mu$m photometry from the Spitzer Survey of Stellar Structure in Galaxies (S${}^4$G) to trace the stellar distribution in nearby disk galaxies ($z\approx 0$) with total st…
