Spectral Dataset of Young Type Ib Supernovae and their Time-evolution
收藏资源简介:
该数据集名为“年轻Ib型超新星及其时间演化的光谱数据集”,由Las Cumbres天文台创建,主要用于研究Ib型超新星的早期光谱特征。数据集包含82个光学光球光谱,其中38个是早期光谱,这些数据增加了已发表的至少有三个早期光谱的Ib型超新星的数量。数据集的创建过程包括使用高频自动化巡天观测,以及通过SNID模板转换和公开数据,以支持超新星的早期识别和分类。该数据集的应用领域主要集中在超新星的分类和早期探测,旨在解决超新星早期分类的复杂性问题,并为未来的大规模巡天项目如Vera C. Rubin天文台的LSST提供支持。
This dataset is named "Spectral Dataset of Young Type Ib Supernovae and Their Temporal Evolution", created by the Las Cumbres Observatory. It is primarily designed for research on the early spectral characteristics of Type Ib supernovae. The dataset contains 82 optical photospheric spectra, 38 of which are early-time spectra. These data increase the number of published Type Ib supernovae with at least three early-time spectra. The dataset was developed using high-cadence automated survey observations, as well as SNID template conversion and publicly available data, to support the early identification and classification of supernovae. Its main application fields focus on supernova classification and early detection, aiming to resolve the complexity of early supernova classification and provide support for future large-scale survey projects such as the LSST at the Vera C. Rubin Observatory.
