RX J0852.0−4622 ADS: search title/keyword/abstract or fulltext

• Right Ascension: 08 52 00
• Declination: −46 20
• Size (/arcmin): 120
• Type: S
• Flux density at 1 GHz (/Jy): 50?
• Spectral Index: 0.3?

Notes: This remnant overlaps the Vela SNR (G263.9−3.3).

Radio: Incomplete shell, confused by the Vela SNR.

Optical: Nebulosity offset to NE.

X-ray: Non-thermal shell, confused by the Vela SNR, with central source, and possible associated pulsar.

Point sources: Central X-ray source, with optical nebula, and possible associated pulsar.

Distance: X-ray data suggest an upper limit of 1 kpc.
