Astronomers find double debris disk around dead star, offering glimpse of Solar System's fate

A rare discovery using the ESO's Very Large Telescope reveals a unique double-disk structure that may foreshadow what happens to planetary systems as their stars die.

What to know

  • A white dwarf system exhibits a rare double debris disk with two gaseous rings separated by a clear gap—the first known system with quadruple-peaked emission lines instead of the double-peaked profiles seen in all 21 previously known gas disks around white dwarfs.
  • Two surviving planetary bodies, possibly including one the size of Pluto, appear to be sculpting the disk structure through their gravitational influence.
  • The discovery challenges existing models of how debris disks form and evolve around white dwarfs and may offer insights into the eventual fate of our own Solar System billions of years from now.

“Unlike in similar systems previously found, the debris—the leftovers of planets that once orbited the star—is organized in a double disk, the two parts separated by a clear gap.”

    Research details unique quadruple-peaked emission line signatures

    Further analysis reveals that the system exhibits quadruple-peaked emission line profiles from two separate gaseous rings, unlike all 21 previously known gas disks around white dwarfs which show double-peaked profiles. The discovery challenges current models of debris disk formation and evolution.

      A dying star 1,600 light-years from Earth is surrounded by two rings of gas and dust that astronomers believe are the remnants of the planetary bodies it once hosted.

    • This is the part that really sticks with me — a dead star still holding on to planetary leftovers. When a Sun-like star becomes a white dwarf, it can shred asteroids and small bodies that wander too close, and that debris forms a ring like this. It makes you wonder how much of our own outer Solar System could survive the Sun's red giant phase and…

    Astronomers spot rare double debris disk around white dwarf

    Astronomers using the ESO's Very Large Telescope discovered a unique debris disk around a dead star with two distinct components separated by a clear gap, shaped by two surviving planetary bodies—one possibly as large as Pluto.
