摘要:

2013年2月,LEECH(LBTI Exozodi Exoplanet Common Hunt)调查开始了100个夜晚的活动,从亚利桑那州格雷厄姆山上的大型双目望远镜开始。LEECH几乎补充了其他高对比度行星成像工作,通过观察L'波段(3.8微米)的恒星,而不是较短波长的近红外波段(1-2.3微米)。这部分光谱为中等年龄(几百万年)的系统提供了更深的质量敏感性,因为它们的木星质量行星主要在中红外辐射。在这篇论文中,我们提出了LEECH的科学目标和一些早期数据的初步对比曲线。

英文摘要:

In February 2013, the LEECH (LBTI Exozodi Exoplanet Common Hunt) survey began its 100-night campaign from the Large Binocular Telescope atop Mount Graham in Arizona. LEECH nearly complements other high-contrast planet imaging efforts by observing stars in L' band (3.8 microns) as opposed to the shorter wavelength near-infrared bands (1-2.3 microns). This part of the spectrum offers deeper mass sensitivity for intermediate age (several hundred Myr-old) systems, since their Jovian-mass planets radiate predominantly in the mid-infrared. In this proceedings, we present the science goals for LEECH and a preliminary contrast curve from some early data.
