Abstract : | T Tauri stars (TTS) are young, low mass (M ≤ 2M☉) pre-main sequence stars, usually associated with molecular clouds, and often found in young associations. The X-ray emission from these stars has been studied earlier but not well understood. In Sun-like stars, X-rays from the corona are due to the presence of the magnetic dynamo, and a similar phenomenon is proposed for the TTS as they possess a sub-surface convective layer. A collective analysis of TTS in different environments might give better insights into this puzzle which has never been explored before. In this work, we obtain the X-ray parameters (X-ray luminosity, plasma temperature, absorption column density, and emission measure) of the TTS in three active star-forming regions - Rho Ophiuchi, Serpens, and Carina from the Chandra data archive and compare them with their optical and infrared properties. This comprehensive study will provide a better understanding of the processes involved in the origin of X-ray emission from TTS. |
