Photometric observations of weak-line T Tauri stars. II. WTTS in Taurus-Auriga, Orion and Scorpius OB2-2.

Abstract (from CDS):

We present uvby-β photometry of 116 X-ray flux-selected active stars in the directions of the Orion (40), Taurus-Auriga (58) and Scorpius OB2-2 (18) star forming regions. Additionally, we give near IR JHK photometry of 20 active stars in the Taurus-Auriga direction. The program stars were selected from the ROSAT All Sky Survey and EINSTEIN X-ray surveys and are spectroscopically confirmed weak-line T Tauri stars and weak-line T Tauri star candidates. The photometry confirms the young nature of the program stars and also indicates that a significant fraction of the sample could be foreground objects. The data given here probably represent the largest homogeneous uvby-β photometric sample of new WTTS and WTTS candidates. Many objects in the sample are observed photometrically for the first time.
