Abstract
We analyzed the distribution of surface gravities,
log
g
, of a sample of classical T Tauri stars in Taurus to examine the relationship between stellar ages and circumstellar disk evolution. This is critical to understanding the timescales for planet formation. Given the uncertainties in
log
g
, we find no distinction between the ages of stars with and without disks beyond that identified previously. This approach, while avoiding the contamination that plagues young star luminosity measurements, will require precisions in
log
g
of 0.05 dex or better to be effective.
