摘要：我们提出了2013年海豚座新星的UBVJHKLM光度观测，该观测在最大光之前几个小时开始，持续了130个夜晚。使用所获得的数据，我们得出了几个光度参数的新星：最大光的时间，亮度在最大值，下降率，t2 = 11天。根据Payne-Gaposchkin的分类，这将Nova Del 2013置于快速新星之列。我们使用银河系消光图和最大光下的绝对亮度通过MMRD关系估计星际变红EB−V = 0.18，MMRD关系使我们能够确定距离D <$2.7 kpc和银河平面以上的高度z <$440 pc。低分辨率光谱显示Nova Del 2013属于Fe II光谱类型的新星。在2013年8月和9月期间观测到的6825附近的宽发射特征可能是拉曼散射的OVI 1032线。
Abstract We present UBVJHKLM photometric observations of Nova Delphini 2013 that started several hours before maximum light and lasted for 130 nights. Using the obtained data, we derived several photometric parameters of the Nova: the time of maximum light, brightness at maximum, rate of decline, t2 = 11 d. This places Nova Del 2013 among fast novae according to the classification introduced by Payne-Gaposchkin. We estimated the interstellar reddening EB−V = 0.18 using maps of Galactic extinction and the absolute brightness in maximum light via the MMRD relation that allowed us to determine the distance D ≈ 2.7 kpc and height above the Galactic plane z ≈ 440 pc. Low-resolution spectroscopy shows that Nova Del 2013 belongs to the Fe II spectral type of novae. The broad emission feature near 6825 Å observed during 2013 August and September may be the Raman-scattered OVI 1032 Å line.
