Abstract

Results of the time variability monitoring of the two classical T Tauri stars, RU Lup and IM Lup, are presented. Three photometric data sets were utilized:(1) simultaneous (same field) MOST satellite observations over four weeks in each of the years 2012 and 2013,(2) multicolour observations at the South African Astronomical Observatory in April– May of 2013,(3) archival V-filter All Sky Automated Survey (ASAS) data for nine seasons, 2001–2009. They were augmented by an analysis of high-resolution, public-domain VLT- ...
