摘要:

我们展示了长期M31监测WeCAP项目中检测到的新星的光变曲线。WeCAPP的目标是用微透镜观测来约束M31晕中致密的暗物质部分。作为一个副产品,我们已经检测到91新星受益于高节奏和高灵敏度的差异成像技术所需的像素化。因此,我们现在可以提供最大的CCD和光学滤波器为基础的新星光变曲线样本最新的M31。由于长期的监测,我们还获得了火山爆发前后光变曲线的全面覆盖。我们将Strope等人(2010)提出的新星分类法应用于我们的新星候选者,发现了29颗S级新星,10颗C级新星,2颗O级新星和1颗J级新星。我们研究了Hachichu和Kato(2006)关于S级新星的普适衰减定律。此外,我们将我们的目录与文献相关联,发现4个潜在的复发新星。我们的部分目录已被用于搜索在M31中探测到的超软X射线源的光学对应物(Pietsch等人,2005)。像WeCAPP这样的光学测量,并与多波长观测相协调,将在未来继续揭示新星的潜在物理机制。

英文摘要:

We present light curves from the novae detected in the long-term, M31 monitoring WeCAPP project. The goal of WeCAPP is to constrain the compact dark matter fraction of the M31 halo with microlensing observations. As a by product we have detected 91 novae benefiting from the high cadence and highly sensitive difference imaging technique required for pixellensing. We thus can now present the largest CCD and optical filters based nova light curve sample up-to-date towards M31. We also obtained thorough coverage of the light curve before and after the eruption thanks to the long-term monitoring. We apply the nova taxonomy proposed by Strope et al. (2010) to our nova candidates and found 29 S-class novae, 10 C-class novae, 2 O-class novae and 1 J-class nova. We have investigated the universal decline law advocated by Hachichu and Kato (2006) on the S-class novae. In addition, we correlated our catalogue with the literature and found 4 potential recurrent novae. Part of our catalogue has been used to search for optical counter-parts of the super soft X-ray sources detected in M31 (Pietsch et al. 2005). Optical surveys like WeCAPP, and coordinated with multi-wavelength observation, will continue to shed light on the underlying physical mechanism of novae in the future.
