论文摘要
我们为Bifrost仪器提供了科学案例和仪器设计注意事项,该仪器将为VLT干涉仪打开短波长(Y/J/H波段),高光谱分散(最高R = 25,000)窗口。 Bifrost将成为ASGARD仪器套件的一部分,并解锁了在Stellar Evolution的早期/晚期阶段研究积聚和损失过程的强大场所,用于检测到年轻恒星周围的原生类星et,并探测直接层次的行星系统和多个恒星系统中的旋转轨道对齐。我们对GAIA二进制文件的调查旨在为一千颗恒星提供质量和精度年龄,提供一个旧数据集,用于改善恒星进化模型以及银河考古学。 Bifrost将在0.025-1“分离范围内实现外轴的外轴光谱法,从而实现高SNR,高光谱分辨率的随访,对ELT和JWST检测到的系外行星的随访。我们对项目的状态进行了更新,对项目的状态进行了更新,概述了我们的关键技术选择,并与其他工具进行了协会,并与Supped Assports insupsgard assgard assgard assgard assgard assgard assgard assgard suite。
We present science cases and instrument design considerations for the BIFROST instrument that will open the short-wavelength (Y/J/H-band), high spectral dispersion (up to R=25,000) window for the VLT Interferometer. BIFROST will be part of the Asgard Suite of instruments and unlock powerful venues for studying accretion & mass-loss processes at the early/late stages of stellar evolution, for detecting accreting protoplanets around young stars, and for probing the spin-orbit alignment in directly-imaged planetary systems and multiple star systems. Our survey on GAIA binaries aims to provide masses and precision ages for a thousand stars, providing a legacy data set for improving stellar evolutionary models as well as for Galactic Archaeology. BIFROST will enable off-axis spectroscopy of exoplanets in the 0.025-1" separation range, enabling high-SNR, high spectral resolution follow-up of exoplanets detected with ELT and JWST. We give an update on the status of the project, outline our key technology choices, and discuss synergies with other instruments in the proposed Asgard Suite of instruments.
