WBVR CBS HZ Her/Her X-1的光度测定

WBVR Photometry of the CBS HZ Her/Her X-1

A. N. Sazonov

摘要:

本文报道了1986-1994年对密近双星HZ HER/HER X-1进行的四色WBVR光电测光。在1986-1990年、1992年和1994年的观测季节中,我们的测光通常至少覆盖两个35天的岁差周期。我们用X射线源对这颗恒星进行了长达10年的光电观测,其精度和持续时间使我们有可能研究它的长期行为。我们对CBS光变曲线上的一些“精细”光度效应进行了修正,并试图用CBS的光学组分到中子星(NS)的吸积盘(AD)的质量传递模型来解释它们。

英文摘要:

We report four-color WBVR photoelectric photometry of the close binary system (CBS) HZ HER/HER X-1 made in 1986-1994. Our photometry usually covered at least two 35d precession periods during each of the 1986-1990, 1992, and 1994 observing seasons. The accuracy and duration of our 10-year long photoelectric observations of the star with an x-ray source made it possible to study its long-term behavior. We refine some of the "fine" photometric effects on the light curves of the CBS and try to interpret them in terms of the model of mass transfer from the optical component of the CBS to the accretion disk (AD) of the neutron star (NS).
