摘要:

我们提出了超新星候选者AT 2018we的光度跟踪观测,它是由盖亚光度警报系统发现的。盖亚对该物体的第一次探测是在2018年2月12日。我们的观测是在2018年2月20日至5月5日期间在Reinins R和Johnson B波段进行的。根据我们的观察,我们已经构建了一个光变曲线,它支持盖亚警报中包含的Ia型的初始预测。基于这种分类,我们还估计了它与假定的宿主星系的距离,发现大约为43 Mpc。

英文摘要:

We present photometric follow-up observations of the supernova candidate AT 2018we, which was discovered by the Gaia photometric alerts system. The first Gaia detection of the object was made Feb 12, 2018. Our observations, made in Cousins R and Johnson B band, range from Feb 20 to May 5, 2018. From our observations, we have constructed a light curve, which supports the initial prediction of type Ia, included in the Gaia alert. Based on this classification, we have also estimated the distance to its assumed host galaxy, which was found to be around 43 Mpc.
