Title: | The search for longer period pre-main sequence stars with SuperWASP |
Topic: | Time Domain |
Abstract: | The longer period pre-main-sequence (PMS) and T Tauri stars present a puzzle to the expected angular momentum evolution of young stars, and additional photometric observations to increase current sample sizes and probe longer period systems are needed. Here we present a sample of previously identified PMS and T Tauri stars observed with SuperWASP-North in La Palma during the 2004-2009 observing seasons. Our main goal was to search for periods longer than 8 days using the extended baseline of SuperWASP observations, and the SuperWASP temporal coverage is over 500 days for selected stars, up to a factor of 15 to 20 greater than those of previous surveys. We will also compare variability measured from SuperWASP optical light curves to a sample of PMS stars observed with the Wide-Field Infrared Survey Explorer (WISE) and Spitzer and as part of YSOVAR. |
