Today I got no research done at all. This behavior is deprecated.
After I spoke at MIT CSR Science Lunch, Burles noted that if (a) the K+A events are triggered by mergers or interactions, and if (b) morphological merger evidence lasts for N dynamical times, where N is relatively independent of dynamical time, then (1) some significant fraction of K+As should show morphological evidence of interactions (duh!), and (2) the fraction should be a linear function of dynamical time, which can be estimated (at least crudely) from the SDSS data themselves. Smart idea, lets do it.
Burles comment was actually about all galaxies, not just post-starburst galaxies. This is particularly interesting for Morad's close-pair project.
