We present results of X-ray spectroscopy for TWA 5, a member o f the young TW Hydrae association, observed with XMM-Newton. TWA 5 is a multiple system which shows H α emission, a signature typical of classical T Tauri stars, bu t no infrared excess. From the analysis of the RGS and EPIC spec tra, we have derived the emission measure distribution vs. temperature of the X-ray emitting plasma, its abundances, a nd the electron density. The characteristic temperature an d de sity of the plasma… CONTINUE READING
