VizieR Online Data Catalog: UV variability and accretion in NGC 2264 (Venuti+, 2015)
Abstract
Our study aims at characterizing the variability signatures at short wavelengths for several hundred accreting and non-accreting members of the star-forming region NGC 2264 (~3Myr). We performed simultaneous, 2-week-long UV (u-band) and optical (r-band) monitoring of the cluster with CFHT/MegaCam, with several flux measurements per observing night to retrace the variability features on timescales from hours to a couple of weeks. Photometric amplitudes and color behaviors are explored to investigate the physical origin of the observed variability in the different cases.
In table2, we present the average u and r photometry measured for individual sources in our sample, their amplitudes of variability, the amount of variability measured via the light curve rms and Stetson's (1996PASP..108..851S) J-index indicator, the r-to-(u-r) amplitude ratio and the uncertainty associated with the latter.
