  "description": "<p>Rieger type periodicity is a mid-range periodicity of 150-200 days in solar activity (Rieger et al. 1984). The periodicity can be found in many solar activity indices. Total solar irradiance permits Sun as a star to study stellar light curves from recent space missions. We study periodic variations of total solar irradiance (TSI) based on SATIRE-S and SOHO/VIRGO data during solar cycles 23-24 on time scales of Rieger-type periodicity. We then compare the power spectrum of oscillations in total solar irradiance to those of sunspot and faculae data to determine their contributions.</p>",
