摘要：

我们介绍了Keck/NIRC 2 $K_{\rm p}L_{\rm p}$高对比度成像观测的J 0337原行星盘。这是继LkH $α$ ~330系统之后，在英仙座恒星形成区的原行星盘中发现的第二个空间分辨的大空洞。我们的数据和正演模拟使用RADMC-3D建议$\sim80$ ~au的空腔半径。J 0337的SED与$\sim10\micron$的模拟SED之间存在差异，这表明存在一个不可见的内部磁盘。我们还搜索了J 0337周围的伴星，但在$0\farcs1$和$2\farcs5$之间的分离处没有检测到任何伴星候选者。$L_{\rm p}$带检测限对应于60 μ m处的$\sim20 M_{\rm Jup}$、90 μ m处的$\sim9-10 M_{\rm Jup}$和$>120$ ~au处的$\sim3 M_{\rm Jup}$.与PDS~70和RX~J1604等年轻的大空洞系统相比，该空洞内可能存在多颗类木行星、一颗偏心类木行星或一颗大质量棕矮星。

英文摘要：

We present Keck/NIRC2 $K_{\rm p}L_{\rm p}$ 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$α$~330 system. Our data and forward modeling using RADMC-3D suggests $\sim80$~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 $L_{\rm p}$-band detection limit corresponds to $\sim20 M_{\rm Jup}$ at 60~au, $\sim9-10 M_{\rm Jup}$ at 90~au, and $\sim3 M_{\rm Jup}$ 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.
