A Quiet Host in an Active Planet-Forming Disk: Optical Spectroscopy of WISPIT 2
C. Swastik, M. Bestha, L. S. Sonith +11
WISPIT 2 is a young pre-main-sequence star hosting a multi-ringed transition disk and two directly imaged protoplanets, including the accreting WISPIT 2b, making it the closest kno…
