论文摘要
使用330 m基线的角度分辨率低至0.1-0.2毫秒的弧线，并访问600-900 nm的光谱域，Chara阵列是理想地配置的，可将其集中在精确且准确的恒星基本参数上。 chara/spica（带有Coph的阵列的恒星参数和图像）旨在对Hertzsprung-Russell图的整个恒星进行大量调查。该调查还将研究不同种类的变异性和表面结构对提取基本参数可靠性的影响。从本调查中提取了新的表面亮度彩色关系，以确定距离和微弱恒星的特征。 Spica由可见的6T纤维仪器和近红外边缘传感器制成。在本文中，我们详细介绍了科学计划和Spica-Vis的主要特征。我们最终介绍了在调试期间获得的初步表现。
With a possible angular resolution down to 0.1-0.2 millisecond of arc using the 330 m baselines and the access to the 600-900 nm spectral domain, the CHARA Array is ideally configured for focusing on precise and accurate fundamental parameters of stars. CHARA/SPICA (Stellar Parameters and Images with a Cophased Array) aims at performing a large survey of stars all over the Hertzsprung-Russell diagram. This survey will also study the effects of the different kinds of variability and surface structure on the reliability of the extracted fundamental parameters. New surface-brightness-colour relations will be extracted from this survey, for general purposes on distance determination and the characterization of faint stars. SPICA is made of a visible 6T fibered instrument and of a near-infrared fringe sensor. In this paper, we detail the science program and the main characteristics of SPICA-VIS. We present finally the initial performance obtained during the commissioning.
