From Stellar to Extragalactic Astronomy at the Armagh Observatory and Planetarium 2021-2024

这项综合拨款招标所涵盖的项目涵盖了恒星、银河系和河外天文学和天体物理学方面的一系列问题。在恒星方面，拟议的项目涉及恒星磁场、恒星耀斑和恒星演化的后期阶段的作用。特别是，我们的目标是了解白矮星磁场的起源，太阳类型恒星和质量较小恒星的高能耀斑的起源，以及一些最奇异和令人费解的富金属恒星的起源。在我们的银河系中，我们的目标是通过绘制产生伽马射线的最稠密气体云的分布，来了解切伦科夫望远镜阵列即将观测到的伽马射线粒子的起源。最后，我们的目标是了解椭圆形和透镜状星系是如何通过吸积其他卫星星系而成长起来的，方法是深入研究它们的恒星外围的性质，在那里这些事件的记录仍然被保存下来。

The projects covered in this consolidated grant bid covers a range of questions in stellar, galactic and extragalactic astronomy and astrophysics. On the stellar side, the proposed projects deals with the role of stellar magnetic fields, stellar flares and the late stages of stellar evolution. In particular, we aim to understand the origin of magnetic fields in white dwarves, of energetic flares in Solar-type stars and less massive stars and of some of the most exotic and puzzling metal-rich stars. In our Galaxy we aim to understand the origin gamma-ray particles as will be soon observed by Cherenkov Telescope Array by mapping the distribution of the densest clouds of gas where gamma rays are produced. Finally, we aim to understand how elliptical and lenticular galaxies grew by accreting other satellite galaxies, by delving in the properties of their stellar outskirts where the record of such events are still preserved.
