J/A+A/417/557      Rotation & variability of PMS Stars in NGC 2264 (Lamm, 2004)

A Rotational and Variability Study of a Large Sample of PMS Stars in NGC 2264 Lamm M.H., Bailer-Jones C.A.L., Mundt R., Herbst W., Scholz A. <Astron. Astrophys. 417, 557 (2004)> =2004A&A...417..557L
ADC_Keywords: Clusters, open ; Stars, pre-main sequence Keywords: open clusters and associations: individual (NGC 2264) - stars: pre-main sequence, rotation, activity, spots - methods: data analysis, time series analysis, periodogram Description: Table 4 lists the 10554 stars in the area of NGC 2264 between IC=9.8mag and IC=21mag on which we did photometry. It contains information on the position, brightness, colours and the variability of these stars. It also lists the spectral type taken from the literature (if available) as well as the identification numbers of the stars in other studies. Table 6 lists the stars detected as periodic in this study and gives their brightness, periods determined by different periodogram techniques, and the period finally adopted as well as the estimated period error. Stars which passed the two adopted PMS tests are also indicated. Time series data were obtained in the IC band in 44 nights between Dec. 2000 and March 2001 with the Wide Field Imager (WFI) on the MPG/ESO 2.2m telescope on La Silla (Chile). File Summary:
