摘要

在某些双色图上，晚巨支的斜率与其他层序的斜率以及变红线的斜率有很大的不同。这一事实使红巨星成为研究恒星参数和星际灭绝的不可或缺的数据来源。本研究旨在寻找适合M巨星参数化的双色图，并发展基于观测光度数据的参数化技术。因此，我们获得了一台仪器，用于测定\(WBVR\)和\(ugriz\)光度系统的本征色指数、光谱类型和星际消光。这篇论文部分基于“现代恒星天文学- 2024”会议上的演讲。

Parameterization of M Giants Based on WBVR and UGRIZ Photometric Data

The slope of the late-giant branch in some two-color diagrams differs considerably from the slope of other sequences as well as from the slope of reddening lines. This fact makes red giants an indispensable sourse of data on stellar parameters as well as on interstellar extinction. This study aims at finding two-color diagrams suitable for parameterization of M giants and developing techniques of parameterisation based on observed photometric data. As a result, we obtained an instrument for determination of intrinsic color indices, spectral types, and interstellar extinction for the \(WBVR\) and \(ugriz\) photometric systems. This paper is based, in part, on the talk presented at the “Modern Stellar Astronomy—2024” conference.
