The resemblance of RX J1713.7-3946 to "Vela Junior'' is particularly striking since both remnants have an identical type of central point source at the center (no optical nor radio counterparts, absence of pulsations, same temperature, luminosity and surface emitting radius), are X-ray synchrotron dominated, have a weak and quite complex radio emission, are found in a complex environment and present an extremely low density of thermally emitting material (Slane et al. 2001).
