21,864 Unresolved, Low-mass Binaries Identified via their Overluminosity in Gaia DR3 and a Catalog of 347,440 Systems within 100 pc of the Sun

This dataset contain the catalogs accompanying the paper "21,864 Unresolved, Low-mass Binaries Identified via their Overluminosity in Gaia DR3 and a Catalog of 347,440 Systems within 100 pc of the Sun" by Zachary Way, Sébastien Lépine, Jonathon Gagné, and Ilija Medan submitted to AAS Journals in January 2026. There are two data files: overluminous_catalog.csv: csv table with 164,297 rows and 7 columns. This table represents the measured and predicted magnitudes/colors of the Full Sample defined in the paper. This corresponds to Table 2. catalog_of_systems_100pc.csv: csv table with 347,440 rows and 206 columns. This table aggregates the signs of multiplicity from several sources and attempts to build a Catalog of Systems. This corresponds to Table 3. catalog_of_systems_100pc_lite.csv: csv table with 347,440 rows and 26 columns. This table is a smaller version of Table 3 that does not include the crossmatched Gaia data. This table is the version uploaded to the AAS journal article. Notes on the Overluminosity Catalog: Reddening for each star was calculated using the dustmaps (Green 2018 [2018JOSS....3..695G]) code and the 3D dust map from Edenhofer et al. (2024) [2024A&A...685A..82E]. We include a match to the BANYAN {Sigma} young associations catalog to flag possible overluminosity due to youth rather than binarity Gagné et al. (2018) [2018ApJ...856...23G]; Gagné (2024) [2024PASP..136f3001G]. Notes on the Catalog of Systems: For multiple components, columns are repeated for each Gaia Source ID in the system. The full version of this catalog, with cross-matched values taken from Gaia DR3, is available on Zenodo: 10.5281/zenodo.18500082. An integer whose binary representation identifies catalog membership. Only the first five bits of the 8 bit array are used. As an example a catalogs-1 value of 176 corresponds to the binary representation as an array [1, 0, 1, 1, 0, 0, 0, 0] and the presence of the source in Shariat et al. (2025), Medan & Lépine (2023), and Hartman & Lépine (2020), and the lack of the same source in El-Badry et al. (2021) and Table 2. The full bit values are as follows: 1st bit = Shariat et al. (2025) [2025PASP..137i4201S]; 2 = El-Badry et al. (2021) [2021MNRAS.506.2269E]; 3 = Medan & Lépine (2023) [2023AJ....166..218M]; 4 = Hartman & Lépine (2020) [2020ApJS..247...66H]; 5 = the overluminosity catalog, Section 3.4, Table 2. List of "|" delimited references (ADS bibcodes) that this source_id belongs to according to MOCAdb, Gagné et al. (2026), accepted. Cifuentes et al. (2025) [2025A&A...693A.228C] Gaia DR3 multiplicity flag本数据集配套于2026年1月投稿至美国天文学会（AAS）期刊的论文《通过盖亚DR3（Gaia DR3）超光度特性识别21864颗未解析低质量双星及太阳100秒差距内347440个系统星表》，作者为Zachary Way、Sébastien Lépine、Jonathon Gagné与Ilija Medan。 本数据集包含三个数据文件： 1. `overluminous_catalog.csv`：该CSV表格共164297行、7列，对应论文中的表2，记录了论文定义的全样本的实测与预测星等及色指数。 2. `catalog_of_systems_100pc.csv`：该CSV表格共347440行、206列，对应论文中的表3，整合了多来源的多重星迹象，旨在构建系统星表。 3. `catalog_of_systems_100pc_lite.csv`：该CSV表格共347440行、26列，是表3的精简版本，不含交叉匹配的盖亚数据，为上传至AAS期刊论文的版本。 ### 超光度星表说明 单颗恒星的红化量通过`dustmaps`（Green 2018 [2018JOSS....3..695G]）工具与Edenhofer等人2024年发布的三维尘埃图[2024A&A...685A..82E]计算得到。 本星表匹配了BANYAN Σ年轻星团目录，用于标记因年轻而非双星造成的超光度信号（Gagné et al. 2018 [2018ApJ...856...23G]; Gagné 2024 [2024PASP..136f3001G]）。 ### 系统星表说明 对于多重星系统，表格会为系统内每个盖亚源ID重复对应列。带有盖亚DR3交叉匹配值的完整版本星表已上传至Zenodo：10.5281/zenodo.18500082。 存在一个整数，其二进制表示用于标识该源的星表成员属性，仅使用8位二进制数组的前5位。示例：catalogs-1值为176时，对应二进制数组为`[1, 0, 1, 1, 0, 0, 0, 0]`，表明该源存在于Shariat等人2025、Medan & Lépine 2023及Hartman & Lépine 2020的研究中，而未出现在El-Badry等人2021的研究及表2中。各比特位含义如下： - 第1位：Shariat et al. (2025) [2025PASP..137i4201S] - 第2位：El-Badry et al. (2021) [2021MNRAS.506.2269E] - 第3位：Medan & Lépine (2023) [2023AJ....166..218M] - 第4位：Hartman & Lépine (2020) [2020ApJS..247...66H] - 第5位：本超光度星表（3.4节，表2） 此外还包含一列以`|`分隔的ADS文献编码（ADS bibcodes），代表根据MOCAdb、Gagné等人2026年已接收论文，该source_id所属的文献。 Cifuentes等人2025 [2025A&A...693A.228C]的盖亚DR3多重性标记
