Protoplanetary disk lifetimes vs. stellar mass and possible implications for giant planet populations
Aims. We study the dependence of protoplanetary disk evolution on stellar mass using a
large sample of young stellar objects in nearby young star-forming regions. Methods. We …

Pre-main-sequence isochrones–II. Revising star and planet formation time-scales
CPM Bell, T Naylor, NJ Mayne… - Monthly Notices of …, 2013 - academic.oup.com
We have derived ages for 13 young (< 30 Myr) star-forming regions and find that they are up
to a factor of 2 older than the ages typically adopted in the literature. This result has wide …
