标题： WISEP J180026.60+013453.1: A Nearby Late L Dwarf Near the Galactic Plane

摘要： 我们报告发现了一颗附近的L7.5矮星，该天体是利用广域红外线巡天探测器（WISE）的初步数据发布和2微米全天巡天（2MASS）发现的。WISEP J180026.60+013453.1具有0.42角秒/年的运动，并且估计距离为8.8 \pm 1.0 pc。凭借这一距离，它目前被列为第六近的已知L型矮星，尽管需要三角视差来确认这一距离。由于它靠近银河平面（b=12），之前被忽略了。作为一颗相对较亮且靠近的晚期L型矮星，具有正常的近红外颜色，W1800+0134将成为研究冷亚恒星大气中云相关现象的基准。 显示英文摘要

摘要： We report a nearby L7.5 dwarf discovered using the Preliminary Data Release of the Wide-field Infrared Survey Explorer (WISE) and the Two Micron All-Sky Survey (2MASS). WISEP J180026.60+013453.1 has a motion of 0.42 arcsec/yr and an estimated distance of 8.8 \pm 1.0 pc. With this distance, it currently ranks as the sixth closest known L dwarf, although a trigonometric parallax is needed to confirm this distance. It was previously overlooked because it lies near the Galactic Plane (b=12). As a relatively bright and nearby late L dwarf with normal near-infrared colors, W1800+0134 will serve as a benchmark for studies of cloud-related phenomena in cool substellar atmospheres.
