PDS 70b Shows Stellar-like Carbon-to-oxygen Ratio

PDS 70b Shows Stellar-like Carbon-to-oxygen Ratio

The ~5 Myr PDS 70 is the only known system with protoplanets residing in the cavity of the circumstellar disk from which they formed, ideal for studying exoplanet formation and evolution within its natal environment. Here, we report the first spin constraint and C/O measurement of PDS 70b from Keck/...
