摘要
年轻主序星周围的碎片盘通常具有间隙和空洞，长期以来被解释为可能由行星引起。近年来，在拥有这种性质盘的系统中发现了几个巨行星，进一步表明与行星的相互作用可能是这种盘结构的常见原因。作为SEEDS高对比度成像巡天的一部分，我们正在巡天一群由光谱能量分布暗示具有间隙和空洞的碎片盘宿主星，以尝试空间分辨盘以及探测可能造成盘结构的任何行星。这里我们报告该巡天的中期结果。五个碎片盘已被空间分辨，并发现了一些暗点源，其中大多数已经过共同自行测试，在每种情况下都排除了与目标星的物理伴星关系。从已观测的50个目标的探测极限，我们发现类似β Pic b的行星（围绕G-A型星的~10 Mjup行星）在间隙边缘附近的出现频率低于15-30%，这意味着如果巨行星是这些宽间隙（平均27 AU）的主要原因，那么它们的质量通常小于β Pic b。
