Disintegrating Rocky Exoplanets

TL;DR

This paper introduces a new class of close-in, disintegrating rocky exoplanets with dusty tails, offering insights into their composition through dust analysis.

Contribution

It presents the discovery and characterization of disintegrating rocky exoplanets, highlighting their dusty effluents as a novel probe of planetary material.

Findings

Disintegrating planets have dusty tails revealing their composition.

These planets are located close to their host stars with hot, molten surfaces.

Dust properties can directly inform about planetary constituent materials.

Abstract

We discuss a new class of exoplanets that appear to be emitting a tail of dusty effluents. These disintegrating planets are found close to their host stars and have very hot, and likely molten, surfaces. The properties of the dust should provide a direct probe of the constituent material of these rocky bodies.
