Mapping accretion variability in NGC 2264
Listed in IVOA Registry (Virtual Observatory)
Our study aims at characterizing the accretion properties of several hundred members of the star-forming region NGC 2264 (3Myr).
Description
We performed a deep u,g,r,i mapping of the cluster with CFHT/MegaCam, and monitored the simultaneous u+r variability of its members over a baseline of two weeks. Stellar parameters are determined homogeneously for about 750 monitored young objects, 40% of which are accreting T Tauri stars.
Accretion properties and accretion variability are investigated and characterized from UV excess measurements. Non-accreting members of the cluster define the reference UV emission level over which flux excess is detected and measured.
