A Spatially-resolved Large Cavity of the J0337 Protoplanetary Disk in Perseus
Abstract
We present Keck/NIRC2 K p L p high-contrast imaging observations of a J0337 protoplanetary disk. The data discover the spatially-resolved large cavity, which is the second report among protoplanetary disks in the Perseus star-forming region after the LkHα 330 system. Our data and forward modeling using RADMC-3D suggests ~80 au for the cavity radius. There is discrepancy between J0337's spectral energy distribution (SED) and the modeled SED at ~10 μm and this suggests an unseen inner disk. We also searched for companions around J0337 but did not detect any companion candidates at separations between 0.″1 and 2.″5. The L p-band detection limit corresponds to ~20M Jup at 60 au, ~9-10M Jup at 90 au, and ~3M Jup at >120 au. Compared with other young systems with large cavities such as PDS 70 and RX J1604, multiple Jovian planets, a single eccentric Jovian planet, or a massive brown dwarf at an inner separation could exist within the cavity.
