OGLE III EWS数据库中的二元晶状体。2005赛季
Binary Lenses in OGLE III EWS Database. Season 2005
摘要:
我们提出了九个新的二元透镜候选人从OGLE-III预警系统数据库的2005年赛季。我们还发现了四个事件解释为单质量透镜的双源。通过视觉光变曲线检查选择候选物。在我们以前的研究中检查二元透镜的模型(1997- 1999年OGLE-II季的10个焦散交叉事件和2002- 2004年OGLE-III季的34个双星透镜事件,包括一个行星事件),在这项工作和2005年三个关于行星事件的出版物中,我们发现了四个极端质量比双星的例子(q<0.01),以及几乎所有其他质量比在0.1<q<1.0范围内的模型,这可能表明行星系统和双星之间的划分。
英文摘要:
We present nine new binary lens candidates from OGLE-III Early Warning System database for the season of 2005. We have also found four events interpreted as single mass lensing of double sources. The candidates have been selected by visual light curves inspection. Examining the models of binary lenses in our previous studies (10 caustic crossing events of OGLE-II seasons 1997--1999 and 34 binary lens events of OGLE-III seasons 2002--2004, including one planetary event), in this work and in three publications concerning planetary events of season 2005, we find four cases of extreme mass ratio binaries (q<0.01), and almost all other models with mass ratios in the range 0.1<q<1.0, which may indicate the division between planetary systems and binary stars.
