Summary
Supernova remnants are what is left after a star explodes: a good part of their emission happens in radio and in X-rays. Here we present the analysis of Vela Jr, carried out with the X-ray all-sky survey dataset provided by the MPE-led mission eROSITA. This dataset allows to image the entire remnant for the first time after the ROSAT mission launched in 1990. We find the spectrum of Vela Jr is featureless and we provide a new measurement for the geometric center. We investigate also the NW rim of the remnant, where particle acceleration is supposed to take place, a process still poorly known.
