Abstract

The ArmazoNes high Dispersion Echelle Spectrograph (ANDES) is the optical and near-infrared high-resolution echelle spectrograph envisioned for the Extremely Large Telescope (ELT). We present a selection of science cases, supported by new calculations and simulations, where ANDES could enable major advances in the fields of stars and stellar populations. We focus on three key areas, including the physics of stellar atmospheres, structure, and evolution; stars of the Milky Way, Local Group, and beyond; and the star-planet connection. The key features of ANDES are its wide wavelength coverage at high spectral resolution and its access to the large collecting area of the ELT. These features position ANDES to address the most compelling questions and potentially transformative advances in stellar astrophysics of the decades ahead, including questions which cannot be anticipated today.

ELT-ANDES 的发现空间。恒星和恒星群

ArmazoNes高色散埃歇尔摄谱仪（ANDES）是为超大望远镜（ELT）设想的光学和近红外高分辨率埃歇尔摄谱仪。在新计算和模拟的支持下，我们介绍了一些科学案例，在这些案例中，ANDES 可以在恒星和恒星群领域取得重大进展。我们将重点放在三个关键领域，包括恒星大气、结构和演化的物理学；银河系、本星系和其他星系的恒星；以及恒星与行星的联系。ANDES的主要特点是具有高光谱分辨率的宽波长覆盖范围和ELT的大收集区。这些特点使 ANDES 能够在未来几十年内解决恒星天体物理学中最引人注目的问题和可能带来的变革性进展，包括今天还无法预料的问题。

期刊介绍： Many new instruments for observing astronomical objects at a variety of wavelengths have been and are continually being developed. Furthermore, a vast amount of effort is being put into the development of new techniques for data analysis in order to cope with great streams of data collected by these instruments. Experimental Astronomy acts as a medium for the publication of papers of contemporary scientific interest on astrophysical instrumentation and methods necessary for the conduct of astronomy at all wavelength fields. Experimental Astronomy publishes full-length articles, research letters and reviews on developments in detection techniques, instruments, and data analysis and image processing techniques. Occasional special issues are published, giving an in-depth presentation of the instrumentation and/or analysis connected with specific projects, such as satellite experiments or ground-based telescopes, or of specialized techniques.
