论文摘要
我们提出了一种使用中频过滤器搜索极地候选物的方法。 Polars的光谱奇异性之一是$ HEII \ lambda4686 $ Å〜强发射线。我们选择了中央波长为470、540和656 nm的Edmund光学滤器和10 nm的传输带宽。这些过滤器分别涵盖了$ heii \ lambda4686 $ Å〜LINE,CONTINUUM和$H_α$线的区域。我们根据SDSS档案中的零红移构建了一个颜色图。我们表明,大多数Porars都是具有独特颜色指数的组。实际上,该方法是在Zeiss-1000望远镜的Sao Ras中实现的,具有新的多模式光度计光度计(MMPP)。对该方法的认可使我们能够制定两个标准,以选择高达75 \%的候选人。
We present a method for searching for polar candidates using mid-band filters. One of the spectral singularities of polars is the $HeII \lambda4686$Å~ strong emission line. We selected the Edmund Optics filters with central wavelengths of 470, 540, and 656 nm and a transmission bandwidth of 10 nm. These filters cover the regions of the $HeII \lambda4686$Å~ line, continuum, and the $H_α$ line respectively. We constructed a color diagram based on the available spectra of polars and objects with a zero redshift from the SDSS archive. We show that most polars make a group with unique color indices. In practice, the method is implemented in SAO RAS at the Zeiss-1000 telescope with a new multi-mode photometer-polarimeter (MMPP). Approbation of the method with the known polars allowed us to develop two criteria to select candidates with an efficiency of up to 75\%.
