  • Distribution of sources in all sky (l,b)

    Save as PNG, Save as EPS

  • Distribution of sources in all sky using Aladin

    Tip: Click on some source to get more informaiton


  • Distribution of sources in IRAS color-color diagram

    Tip: Use "Box select" or "Lasso select" to display colour-selected sources in Aladin all-sky view

    Tip: Click on some source to look at the different surveys. You must select some surveys in previous page at "View images"

    Original color diagram is taken form van der Veen & Habing (1987)

    Type Description
    I Oxygen-rich non-variable stars without circumstellar shells
    II Variable stars with "young" O-rich circumstellar shells
    IIIa Variable stars with more evolved O-rich circumstellar shells
    IIIb Variable stars with thick O-rich circumstellar shells
    IV Variable stars with very thick O-rich circumstellar shells
    V Planetary nebulae and non- variable stars with very cool circumstellar shells
    VIa Variable stars with relatively cold dust at large distances; a significant part of the stars is carbon-rich
    VIb Variable stars with relatively hot dust close to the star and relatively cold dust at large distances; Some of the objects have proven to be O-rich
    VII Variable stars with more evolved C-rich circumstellar shells
    VIII Different sort of objects

  • Distribution of the detection velocities versus galactic longitude from LAN92

    Tip: Use "Box select" or "Lasso select" to display velocity-selected sources in Aladin all-sky view
