| ABSTRACT | |
| Accretion in young, low-mass stars causes emission from X-ray to NIR wavelengths. The UV emission component of protostellar accretion will be studied by the HST DDT legacy program ULLYSES in a once-in-a-generation investment of HST resources. However, most of the accretion-powered emission, including the UV regime, is reprocessed X-ray radiation from the immediate post-shock emission. Therefore, we propose simultaneous XMM-Newton RGS spectroscopy accompanying the ULLYSES monitoring targets (3 stars, 5 epochs each). This will allow us, for the first time, to directly identify physically related phenomena through their shared variability and to decipher the physics of accretion through line-resolved spectroscopy at X-ray and UV wavelengths. | |
