摘要:

综述了相互作用双星中的不稳定性类型。"经度间天文学"项目是一系列关于具体恒星或恒星群的较小项目。它没有特别基金,在设立非正式工作组时,由参加组织的资源和赠款支助。我们总共研究了1900多颗不同类型的变星。典型的时间尺度是从几秒到几十年,(外推)甚至更多。对我们的样本AM Her的第一颗恒星的监测是由V.P. Tsesevich教授(1907 - 1983)发起的。自2005年以来,共发表了358篇ADS论文。介绍了我们对不同类型的相互作用双星进行光度和偏振监测和数学模拟的一些重点:经典、异步、中间极和磁矮星新星(DO Dra),它们有25个时标,对应于不同的物理机制及其组合(部分"极地");在类新星和许多矮新星中的负和正超级巨星("Superhumper");食"非磁性"激变变星;共生系统("共生");超软源(SSS,QR And);发现(并且没有发现)使变量黯然失色,(和没有)目前的质量转移(“质量转移”)的证据,特别强调系统的直接影响流到gainer星的大气层,或V361天琴座型恒星。ILA项目的其他部分是"Stellar Bell"(不同类型和周期的有趣脉动变星-M,SR,RV Tau,RR Lyr,Delta Sct)和"新手"(="新变星")发现和分类,随后监测搜索和研究可能的多个变星成分。已经开发了特殊的数学方法来创建一套补充软件,用于不同类型的变星的统计最佳建模。

英文摘要:

The types of instability in the interacting binary stars are reviewed. The project "Inter-Longitude Astronomy" is a series of smaller projects on concrete stars or groups of stars. It has no special funds, and is supported from resources and grants of participating organizations, when informal working groups are created. Totally we studied 1900+ variable stars of different types. The characteristic timescale is from seconds to decades and (extrapolating) even more. The monitoring of the first star of our sample AM Her was initiated by Prof. V.P. Tsesevich (1907-1983). Since more than 358 ADS papers were published. Some highlights of our photometric and photo-polarimetric monitoring and mathematical modelling of interacting binary stars of different types are presented: classical, asynchronous, intermediate polars and magnetic dwarf novae (DO Dra) with 25 timescales corresponding to different physical mechanisms and their combinations (part "Polar"); negative and positive superhumpers in nova-like and many dwarf novae stars ("Superhumper"); eclipsing "non-magnetic" cataclysmic variables; symbiotic systems ("Symbiosis"); super-soft sources (SSS, QR And); spotted (and not spotted) eclipsing variables with (and without) evidence for a current mass transfer ("Eclipser") with a special emphasis on systems with a direct impact of the stream into the gainer star's atmosphere, or V361 Lyr-type stars. Other parts of the ILA project are "Stellar Bell" (interesting pulsating variables of different types and periods - M, SR, RV Tau, RR Lyr, Delta Sct) and "Novice"(="New Variable") discoveries and classification with a subsequent monitoring for searching and studying possible multiple components of variability. Special mathematical methods have been developed to create a set of complementary software for statistically optimal modelling of variable stars of different types.
