测光精度的新水平:食双星的WIRE观测

A new level of photometric precision: WIRE observations of eclipsing binary stars

Hans Bruntt, John Southworth

摘要:

WIRE卫星于1999年3月发射,是第一个从空间对大量恒星进行星震学研究的空间飞行任务。WIRE已经对几百颗亮星(V <6)进行了非常高精度的测光,时间覆盖数周,包括K巨星、类太阳恒星、盾牌座δ恒星和造父β星。在目前的工作中,我们将描述在七个分离的食双星系统上完成的科学状况。我们的研究结果强调了一些挑战和令人兴奋的结果,预计从未来的卫星任务,如COROT和开普勒。不幸的是,在2006年10月23日,与WIRE的通信在太空中将近八年后失败。由于这个不幸的消息,我们将在本文的最后简要介绍WIRE的历史。

英文摘要:

The WIRE satellite was launched in March 1999 and was the first space mission to do asteroseismology from space on a large number of stars. WIRE has produced very high-precision photometry of a few hundred bright stars (V<6) with temporal coverage of several weeks, including K giants, solar-like stars, delta Scuti stars, and beta Cepheids. In the current work we will describe the status of science done on seven detached eclipsing binary systems. Our results emphasize some of the challenges and exciting results expected from coming satellite missions like COROT and Kepler. Unfortunately, on 23 October 2006, communication with WIRE failed after almost eight years in space. Because of this sad news we will give a brief history of WIRE at the end of this paper.
