论文摘要
GAIA光度计算警报（GPSA）发布了Gaia G幅度和蓝色光度计（BP）和红色光度计（RP）瞬态事件的低分辨率时期光谱。还发布了12个GPSA的Gaia径向速度光谱仪（RV）的27个高分辨率光谱。这27个RVS时期的光谱首次在单个位置呈现在相应的BP和RP时期光谱旁边。我们还提出了第13个GPSA的一个新的RVS频谱，该频谱无法由GPSA系统发布。在带有RVS光谱的13个GPSA中，有5个被归类为未知的，其中5个为超新星（三个为SN IA，一个为SN II，一个为SN IIP），一个是灾难性变量，一个是二进制微验证事件，一个是年轻的恒星对象。被归类为未知的五个GPSA是潜在的科学机会，而所有GPSA都是将在Gaia的第四个数据发布中发布的时期RVS光谱的预览。
Gaia Photometric Science Alerts (GPSA) publishes Gaia G magnitudes and Blue Photometer (BP) and Red Photometer (RP) low-resolution epoch spectra of transient events. 27 high-resolution spectra from Gaia's Radial Velocity Spectrometer (RVS) of 12 GPSAs have also been published. These 27 RVS epoch spectra are presented next to their corresponding BP and RP epoch spectra in a single place for the first time. We also present one new RVS spectrum of a 13th GPSA that could not be published by the GPSA system. Of the 13 GPSA with RVS spectra, five are photometrically classified as unknown, five as supernovae (three as SN Ia, one as SN II, one as SN IIP), one as a cataclysmic variable, one as a binary microlensing event and one as a young stellar object. The five GPSAs classified as unknown are potential scientific opportunities, while all of them are a preview of the epoch RVS spectra that will be published in Gaia's fourth data release.
