AI 中文摘要
地基和空间望远镜上的过往及现有仪器提供了海量大质量恒星的光谱数据，已超出人工检查流程的处理能力，因此迫切需要全自动的机器辅助工具来处理传入数据。为此，我们开发了大质量恒星光谱交互式数据库 Astro+，旨在为用户提供可靠、通用且易用的平台，这对理解大质量恒星具有重要意义，也为未来开放获取的天体物理研究树立重要先例。该工具允许授权用户上传自己的光谱，通过基于 Python 的全自动工具 HiLineThere，可完全自主地利用 FASTWIND 模型的太阳金属丰度网格，均匀推导大质量 O、B 型恒星的 v_rad、v sin i、Teff 和 log g 等基本恒星参数，以及红超巨星的 v_rad、[Fe/H]、Teff 和 log g 等参数。本文呈现了 HiLineThere 工具对 O、B 型恒星和红超巨星光学光谱的首批结果：我们将 O、B 型恒星的分析输出与大量已深入研究天体的文献值对比，发现差异在预期误差范围内，即 Teff 约 800 K，log g 约 0.1 dex，v sin i 约 10 km/s；对早 B 型恒星的初步测试显示，其向更低温度过渡期间结果一致；对两个红超巨星测试样本，v_rad 差异在 7 km/s 以内，Teff 差异约 300 K。
英文摘要
The vast amounts of spectroscopic data for massive stars provided by previous and existing instruments on ground-based and space-based telescopes have saturated our capability to process them by human inspection routines. Consequently, there is a pressing need for fully automatic machine-assisted tools to help handle incoming data. To this end, we present the development of a massive star spectroscopic interactive database, Astro+. We aim to provide users with a reliable, versatile, and user-friendly platform that will be significant for understanding massive stars and set an important precedent for future open-access astrophysical research. This tool allows authorized users to upload their own spectra and, by using the fully automated tool HiLineThere, a Python-based program, it can homogeneously derive basic stellar parameters, such as v_rad, v sin i, Teff and log g for massive OB-type stars, using a solar-metallicity grid of FASTWIND models, and v_rad, [Fe/H], Teff and log g for red supergiant stars, in a completely autonomous way. Here we present the first results of the tool HiLineThere on optical spectra for OB-type stars and red supergiants. We compare the output of our analysis for OB-type stars with literature values for a large sample of well-studied objects, finding differences within the expected error ranges: Teff ~ 800 K, log g ~ 0.1 dex, and v sin i ~ 10 km/s. Preliminary tests on early-B stars also show consistent results during the transition to lower temperatures. For red supergiants, we find differences within 7 km/s in v_rad and ~300 K in Teff for two test samples.
