Abstract (from CDS):

We present the results from a survey of interstellar absorptions towards the supernova remnant (SNR) RX J0852.0–4622. The distribution of KI absorbers along the distance of the background stars is indicative of a local region (d < 600pc) strongly depopulated by KI line-absorbing clouds. This fact is supported by the behaviour of the interstellar extinction. We find four high-velocity CaII components with velocities of >100km/s towards three stars and we identify these with shocked clouds of the Vela SNR. We reveal and measure the acceleration of two shocked clouds on the approaching and receding sides of the Vela SNR along the same line of sight. The acceleration, velocity and CaII column density of the clouds are used to probe their parameters. The total hydrogen column density of both accelerating clouds is found to be similar ( ∼ 6 {x} 1017/cm2), which indicates that there is possibly a significant number of small-sized clouds in the vicinity of the Vela SNR.

Based on observations collected at the European Southern Observatory, Chile, 080.D-0012(A)
