所有已知的银河系复发新星的综合光度历史

Comprehensive Photometric Histories of All Known Galactic Recurrent Novae

Bradley E. Schaefer

摘要:

我收集了几乎所有已知的银河系复发新星(RNe)和他们的37个已知的爆发测光。这包括我对几乎所有档案印版的现代测量(提供了37次已知喷发中一半的唯一数据),我自己从1987年到现在的10,000个CCD星等(提供了7个RNe的几乎所有静止星等),业余天文学家记录了超过140,000个视星等估计值(他发现了一半已知的火山爆发),以及所有文献中的小规模分散。由此,我生产各种统一的产品;(1)BVRIJHK比较星等和BV比较星序,以涵盖整个喷发范围,(2)所有喷发的完整光变曲线,(3)最佳拟合B和V光变曲线模板,(4)除一个RN外的所有RN的轨道周期,(5)对所有错过的喷发的详尽搜索,(6)自1890年以来测量的发现效率,(7)真实重现时间尺度,(8)预测的下一次喷发日期,(9)分钟、小时、天、月、年、十年和世纪时间尺度的变化,(10)到所有RNe的均匀距离和距离,(11)峰值BV颜色和最小值UBVRIJHK颜色,所有消光校正,以及(12)UBVRIJHK上的光谱能量分布。这项工作的亮点包括发现一个新的RN,六个以前未发现的爆发,以及发现一半RNe的轨道周期。这项工作的目标是提供统一的人口统计数据,以回答诸如“我们银河系中RNe的死亡率是多少?”“和”白矮星在每个喷发周期中质量是增加还是减少?'.这项工作的一个重要用途是研究RNe是否可以成为Ia型超新星的祖先。

英文摘要:

I collect virtually all photometry of the ten known galactic recurrent novae (RNe) and their 37 known eruptions. This consists of my modern measures of nearly all archival plates (providing the only data for half of 37 known eruptions), my own 10,000 CCD magnitudes from 1987 to present (providing virtually all of the magnitudes in quiescence for seven RNe), over 140,000 visual magnitude estimates recorded by amateur astronomers (who discovered half the known eruptions), and the small scattering of magnitudes from all the literature. From this, I produce various uniform products; (1) BVRIJHK comparison star magnitudes and BV comparison star sequences to cover the entire range of eruption, (2) complete light curves for all eruptions, (3) best fit B and V light curve templates, (4) orbital periods for all-but-one RN, (5) exhaustive searches for all missed eruptions, (6) measured discovery efficiencies since 1890, (7) true recurrence time scales, (8) predicted next eruption dates, (9) variations on time scales of minutes, hours, days, months, years, decades, and century, (10) uniform distances and extinctions to all RNe, (11) BV colors at peak and UBVRIJHK colors at minimum all with extinction corrections, and (12) the spectral energy distributions over UBVRIJHK. Highlights of this work include the discoveries of one new RN, six previously-undiscovered eruptions, and the discovery of the orbital periods for half the RNe. The goal of this work is to provide uniform demographics for answering questions like the `What is the death rate of RNe in our galaxy?' and `Are the white dwarfs gaining or losing mass over each eruption cycle?'. An important use of this work is for the question of whether RNe can be the progenitors of Type Ia supernovae.
