RZ Piscium

[11] RZ Piscium has been found to emit large amounts of infrared radiation,[9] suggesting the presence of a substantial mass of gas and dust orbiting the star, possibly from a "disrupted planet".

[6][12] Because of the infrared excess and rapid light variations, astronomers conclude that: destruction of one or more massive orbiting bodies has recently occurred within 1 au of the star, and we are viewing the aftermath of such an event along the plane of the orbiting debris.

[8]According to astronomer Ben Zuckerman: Most sun-like stars have lost their planet-forming disks within a few million years of their birth.

The fact that RZ Piscium hosts so much gas and dust after tens of millions of years means it is probably destroying, rather than building, planets.

The incandescence of the companion star thus make up about one third of excess infrared emission previously attributed to the dust.
