论文摘要
我们报告了光带中隐藏共生星Su lyn的光度观测。在五个晚上，我们检测到幅度约为0.05的U带中的弱闪烁。在B，V，G'和r'频段中未发现视频变化。这又表明次要成分是以低积聚率积聚的白色矮人。我们还搜索了十几个相关对象（RR Boo，Rt Boo，Am Cyg，Ag PEG，BF Cyg，NQ Gem，STHA190，V627 CAS，XX OPH，FS CET和Y GEM），其中未检测到观察误差以上的可变性。
We report photometric observations of the hidden symbiotic star SU Lyn in the optical bands. In five nights we detect a weak flickering in U band with amplitude of about 0.05 magnitudes. No intranight variations are found in B, V, g' and r' bands. This is one more indication that the secondary component is a white dwarf accreting at low accretion rate. We also searched for intranight variability of a dozen related object (RR Boo, RT Boo, AM Cyg, AG Peg, BF Cyg, NQ Gem, StHa190, V627 Cas, XX Oph, FS Cet and Y Gem) in which no variability above the observational errors is detected.
