论文摘要
我们介绍了由4LGSF及其激光层析成像自适应光学模块Galacsi提供的VLT/Muse Integralliant光谱仪获得的最新结果。虽然这种所谓的窄场缪斯模式并非旨在直接对系外行星和流出进行成像，但我们表明，在适度的对比下，它可以改变并以突出的排放线（即Hα，示踪剂）（即Hα，示踪剂）来检测和表征年轻的系外行星。得益于接近划分有限的PSF和中等分辨率光谱仪以及后处理中的互相关方法的组合，可以实现这些性能。我们在地面和空间，红外和可见的波长的背景下进行讨论，为JWST和WFIRST等任务做准备，并在Great Synergy中，作为未来ELT/GSMT的探路者（极大的和/或巨大的分段镜像望远镜）仪器。
We present recent results obtained with the VLT/MUSE Integral Field Spectrograph fed by the 4LGSF and its laser tomography adaptive optics module GALACSI. While this so-called narrow-field mode of MUSE was not designed to perform directly imaging of exoplanets and outflows, we show that it can be a game changer to detect and characterize young exoplanets with a prominent emission lines (i.e Hα, tracer of accretion), at moderate contrasts. These performances are achieved thanks to the combo of a near-diffraction limited PSF and a medium resolution spectrograph and a cross-correlation approach in post-processing . We discuss this in the context of ground and space, infrared and visible wavelengths, preparing for missions like JWST and WFIRST in great synergy and as pathfinder for future ELT/GSMT (Extremely Large and/or Giant Segmented Mirror Telescopes) instruments.
