This work finds a systematic offset of 5.5 ± 1.1 Myr between estimates of the ages of stars made with two popular techniques: isochronal fitting and dynamical traceback. This offset is proposed to represent the time a young star remains bound to its parental cloud before dispersing and could help to improve stellar evolutionary models.
