【摘要】 老新星武仙V533(V533Her=武仙1963年新星)是一颗光度变化极其复杂的天体。本文给出了我们用双筒天体照相仪于1980年6月至1982年11月间对其所做的照相观测结果。从所得结果可以看到:(1)该星亮度在此期间已基本恢复到其爆前的宁静期亮度;(2)高时频观测指出V533 Her具有时标为小时级,变幅Δm～0.2~m的小幅度光变;(3)在此期间其亮度有上升趋势,上升幅度～1.5等。本文还讨论了V533 Her在爆发前后的光度变化情况,通过分析指出新星在爆发前可能有可觉察的光度变化。更多还原

【Abstract】 The old nova V533 Her (=N Her 1963) is a celestial object with complicated light variations. The photographic observing results of V533 Her using the 40/200 cm Double Astrograph of Beijing Observatory, from June 1980 to November 1982 are given in this paper. The photographic magnitudes were measured with an Iris Photometer and calibrated by the photo-sequence of the Selected Area SA 88.These results indicate that:(1) During the observing period the old nova declined approximately to the pre-nova level at mpg f33 15. But the brightness fluctuation is unstable.(2) From the light-curve of V533 Her we have found that a long-term brightness fluctuation existed with a range of more than one magnitude (Δm ≈ 1.m5).(3) Short-term fluctuations (Δm ≈ 0.m2) also existed during one night of our observations.更多还原
