Vela (XYZ) ADS: search title/keyword/abstract or fulltext

• Right Ascension: 08 34 00
• Declination: −45 50
• Size (/arcmin): 255
• Type: C
• Flux density at 1 GHz (/Jy): 1750
• Spectral Index: varies

Notes: This refers to the whole Vela XYZ complex, of which X has at times been classified as a separate (filled-centre) remnant. This remnant is overlapped by G260.4−3.4 and G266.2−1.2.

Radio: Large shell, with flatter spectrum component (Vela X), and pulsar nebula.

Optical: Filaments.

X-ray: Patchy shell, with extensions, central nebula and pulsar.

Point sources: Pulsar within Vela X, with one-sided ‘jet’.

Distance: Vela pulsar parallax gives 0.3 kpc, optical spectra and HI studies suggest 0.25 kpc.
