[astro-ph.EP] Interplanetary dust particles (IDPs) are present throughout the Solar System, with Earth experiencing a mass flux of roughly 100 tonnes of IDPs per day.
![Simulated ablation heights of IDPs in exoplanet atmospheres. Our fiducial simulation is marked in red. Solid and dashed curves signify IDP compositions of MgSiO3 and Fe, respectively. The black dashed curve on the left most panel shows the approximation of the mass injection function Fv(p) for an arbitrary IDP mass flux for comparison with the ablation profiles. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/Interplanetary-Dust.png?resize=1200%2C721&ssl=1)
