论文摘要
我们介绍Keck/Nirc2 $ K _ {\ rm P} l _ {\ rm P} $高对比度成像观测值J0337 Protoplanetary Disk。数据发现了空间分辨的大型腔，这是在LKH $α$ 〜330系统之后，在珀尔修斯星形成区域中的原星盘中的第二份报告。我们使用RADMC-3D进行的数据和正向建模建议$ \ sim80 $ 〜AU用于腔半径。 J0337的SED和以$ \ sim10 \ micron $为单位的SED之间存在差异，这表明一个看不见的内磁盘。我们还搜索了J0337附近的同伴，但没有在$ 0 \ farcs1 $和$ 2 \ farcs5 $之间检测到任何同伴候选人。 $ l _ {\ rm p} $ - 频段检测极限对应于$ \ sim20 m _ {\ rm jup} $ 60〜au，$ \ sim9-10 m _ {\ rm jup} $ at 90〜 au和$ \ sim3 m _ _ _ {与其他具有较大空腔的年轻系统（例如PDS〜70和RX〜J1604），多个Jovian行星，单个偏心的Jovian行星或内部分离的巨大棕色矮人。
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.
