Precise and efficient modeling of stellar-activity-affected solar spectra using SOAP-GPU

The simulated spectral time series generated using SOAP-GPU is based on the extraction of active regions from Solar Dynamics Observatory (SDO) data. The positions of sunspots and faculae on the solar disk at each time step are obtained from magnetogram and intensity maps, which are then input into SOAP-GPU to simulate the corresponding spectra. Comparison with HARPS-N solar spectra demonstrates that SOAP-GPU can accurately model the solar RV time series with a precision of 0.9 m/s.本数据集包含的由SOAP-GPU生成的模拟光谱时间序列，其构建基础为从太阳动力学天文台（Solar Dynamics Observatory, SDO）观测数据中提取的太阳活动区信息。各时间步下太阳黑子与光斑在日面的位置信息均取自磁图与强度分布图，随后将此类位置信息输入SOAP-GPU以模拟对应光谱。经与HARPS-N太阳光谱比对验证，SOAP-GPU可精准模拟太阳视向速度（Radial Velocity, RV）时间序列，建模精度可达0.9 m/s。
