Observational Astrophysics at Armagh (Travel Funds)

阿尔马天文台对多种恒星的起源和演化进行研究。其中一些行星的质量比太阳小得多，而且从未真正开启过它们的核引擎。另一些恒星的质量要大得多，它们的核燃料已经消耗殆尽。这两种类型的起源和结构的线索都来自于研究它们的表面，来自脉动或耀斑的活动，来自对它们大气中化学丰度的研究，以及对它们的磁场的研究。除了了解恒星起源，对耀斑和场的研究还有助于了解太阳的活动--太阳是我们唯一可以近距离研究的恒星。这笔赠款将提供前往天文台的旅费，以使天文台成为探索这些问题所必需的天文台。

The Armagh Observatory carries out research into the origin and evolution of many types of stars. Some of these are much less massive than the Sun, and have never really switched on their nuclear engine. Others started life as much more massive stars, and have burnt up their nuclear fuel. Clues to the origin and structure of both types come from studying their surfaces, from activity due to pulsation or flares, from studies of chemical abundances in their atmospheres, and from studies of their magnetic fields. As well as learning about stellar origins, studies of flares and fields help to understand activity in the Sun -- the only star we can study at close range. This grant will provide support for travel to observatories to make the observatons necessary to explore these questions.
