Abstract
Young stars are surrounded by proto-planetary disks, the birthplaces of exoplanets, for the first few Myrs of their existence. Low-mass stars, called classical T Tauri stars (CTTS) in this phase, accrete mass from the inner rim of the disk. This accretion process causes emission from the X-ray to NIR. The UV component of this excess emission will be studied by a large HST DDT program called ULLYSES which includes spectroscopic monitoring of four nearby low-mass stars. We propose contemporaneous NICER observations to identify correlations between X-ray emission from corona and accretion shock and FUV lines and continuum from reprocessed shock emission. Temporal correlations will allow us to identify which components are physically related.
