RT Journal Article T1 Pre main sequence stars as UV sources for the World Space Observatory-UV mission A1 Gómez De Castro, Ana Inés A1 Lamzin, Sergei A. AB Pre-main sequence stars are bright UV (UV) sources compared with their main sequence analogues. The source of this excess is the high energy processes associated with the physics of accretion/outflow during early stellar evolution. In this review, the main sources of UV excess are described as well as the most significant "unknowns" in the field. Special emphasis is made on the results from the last observations carried out with the Hubble Space Telescope and on the relevance of future dedicated monitoring programs with the World Space Observatory-UV.
