Impact of Magnetic Activity on Disk Chemistry and Planet Atmospheres

Quantify how flares, coronal mass ejections, and magnetic reconnection events influence protoplanetary disk chemistry, ionization structure, and the early atmospheric evolution of close-in forming planets.

Background

The authors highlight that energetic magnetic events can affect disk ionization and chemistry, with implications for planet formation and habitability. Time-resolved spectroscopy is needed to connect event energetics to changes in disk conditions and nascent planetary atmospheres.

Here are the major open questions that the next big telescope developed by ESO will address through conducting a decadal spectroscopic survey of YSOs: How do these events influence disk chemistry, ionization structure, and the early atmospheric evolution of close-in forming planets?
