A spatially-resolved large cavity of the J0337 protoplanetary disk in Perseus

Abstract

We present Keck/NIRC2 $K_{\mathrm{p}}{L}_{\mathrm{p}}$ 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 LkH$\hat{I}\pm$~330 system. Our data and forward modeling using RADMC-3D suggests $\sim 80$~au for the cavity radius. There is discrepancy between J0337's SED and the modeled SED at $\sim10\micron$ and this suggests an unseen inner disk. We also searched for companions around J0337 but did not detect any companion candidates at separations between $0\farcs1$ and $2\farcs5$. The $L_{\mathrm{p}}$-band detection limit corresponds to $\sim 20M_{\mathrm{Jup}}$ at 60~au, $\sim 9-10M_{\mathrm{Jup}}$ at 90~au, and $\sim 3M_{\mathrm{Jup}}$ 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.
