Long-term variability of T Tauri stars using WASP

The research leading to these results has received funding from the European Union Seventh Framework Programme FP7-2011 under grant agreement no 284405. WASP-South is hosted by the South African Astronomical Observatory, and Super-WASP-North by the Isaac Newton Group and the Instituto de Astrofisica de Canarias; we are grateful for their ongoing support and assistance. Funding for WASP comes from consortium universities and from the UK’s Science and Technology Facilities Council. This publication makes use of VOSA, developed under the Spanish Virtual Observatory project supported from the Spanish MICINN through grant AyA2008-02156.
