Direct Spectroscopic Confirmation of the Young Embedded Protoplanet WISPIT 2c

WISPIT 2 is a nearby young star with a multiringed disk that was recently confirmed to host a ∼4.9 M _Jup gas giant planet embedded in a large (60 au) gap at a radial separation of 57 au from the host star. We confirm and characterize a second, close-in planet in the WISPIT 2 system using a combinat...
