Briefings

On October 22, 2026, APOD featured WD J1330+6435, a white dwarf star with an accretion disk. The image illustrates the star surrounded by gas and rocks, noting that some white dwarfs appear yellow, green, cyan, pink, or purple due to trace elements shifting their color. The author expressed hope that future observations would reveal these faint colors, though none were visible that night.

Key points

• The featured object is WD J1330+6435, a white dwarf star with an accretion disk containing gas and rocks.
• Trace elements accreted to the star shifted its color to yellow, green, cyan, pink, or purple, though none were visible on October 22, 2026.

Context

APOD presents daily images of the cosmos with explanations by professional astronomers. This specific image illustrates a white dwarf star surrounded by an accretion disk, highlighting how trace elements can alter stellar color despite the star's name.

Limitations

The evidence is a single APOD article from October 22, 2026, with no additional data on the star's properties, observations, or future discoveries.
