[1] The proximity of this moving group makes it useful for studies of shared stellar properties, as well as detection of companions through direct imaging.
Luhman, Stauffer, & Mamajek (2005)[4] demonstrated that the AB Dor Moving Group and Pleiades open cluster have a similar pattern of Lithium depletion and color-magnitude diagram positions amongst their low-mass members, suggesting that the two groups were of similar age (~100-125 Myr).
Ortega et al. (2007)[5] integrated the past Galactic orbits of the AB Dor Moving Group and the Pleiades cluster, and concluded that they were in close proximity 119 ± 20 Myr ago.
In 2013, a color-magnitude analysis of the low-mass stars in the group by Barenfeld et al. (2013)[6] found that the members of spectral type K6 and hotter appeared to be on the main sequence, whereas the cooler M-type stars are pre-main sequence - consistent with a lower limit on the age of the AB Dor Moving Group of >110 Myr.
The latter study also concluded that some members of the moving group outside of the nucleus do not share a common chemical composition, implying that they are unrelated interlopers.
