类太阳振荡星作为银河系研究的标准时钟和标尺
Solar-like oscillating stars as standard clocks and rulers for Galactic studies
摘要:
CoRoT和开普勒太空任务已经探测到数百颗类太阳恒星和数千颗红巨星的振荡。这为银河系恒星星族研究的新时代打开了大门。我们报告了收集空间测光数据用于合奏asteroseismology的现状和未来前景,并强调了使用这些恒星作为银河系研究的精确时钟和标尺所需面临的一些挑战。
英文摘要:
The CoRoT and Kepler space missions have detected oscillations in hundreds of Sun-like stars and thousands of field red-giant stars. This has opened the door to a new era of stellar population studies in the Milky Way. We report on the current status and future prospects of harvesting space-based photometric data for ensemble asteroseismology, and highlight some of the challenges that need to be faced to use these stars as accurate clocks and rulers for Galactic studies.
