论文摘要
MIRC-X是Chara阵列的六个望远镜梁组合仪,它在J和H波长频段中起作用,并提供了相当于A $ B $ = 3.31亿台直径望远镜的角度分辨率。传统MIRC组合商在恒星天体物理学和二进制领域取得了出色的成绩。但是,我们需要更高的灵敏度,以对诸如年轻恒星对象,具有系外行星和主动银河系核等微弱目标的科学测量进行雄心勃勃的科学测量。为此,MIRC-X是自2017年中以来建造并提供给社区的。 MIRC-X以最佳案例H <= 8的方式证明了多达两种改善的微弱幅度灵敏度。在这里我们介绍了该仪器的评论并提出了早期的科学结果,并突出了一些我们正在进行的科学计划。
MIRC-X is a six telescope beam combiner at the CHARA array that works in J and H wavelength bands and provides an angular resolution equivalent to a $B$=331m diameter telescope. The legacy MIRC combiner has delivered outstanding results in the fields of stellar astrophysics and binaries. However, we required higher sensitivity to make ambitious scientific measurements of faint targets such as young stellar objects, binary systems with exoplanets, and active galactic nuclei. For that purpose, MIRC-X is built and is offered to the community since mid-2017. MIRC-X has demonstrated up to two magnitudes of improved faint magnitude sensitivity with the best-case H <= 8. Here we present a review of the instrument and present early science results, and highlight some of our ongoing science programs.
