A Rotational Period Study of a Large Sample of Pre-Main Sequence stars in NGC 2264
Published online by Cambridge University Press: 26 May 2016
Abstract
We present the results of a photometric monitoring program of pre-main sequence (PMS) stars in the young (2-4 Myr) open cluster NGC 2264 (d=700 pc). We find that the rotation periods are mass dependent and show a bimodal distribution for higher mass stars with M ≳ 0.3 M⊙ and a unimodal distribution for lower mass stars with M ≲ 0.3 M⊙.
