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.

在这个综合赠款投标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的一系列问题。在恒星方面，拟议的项目涉及恒星磁场的作用、恒星耀斑和恒星演化的后期阶段。特别是，我们的目标是了解磁场的起源在白色矮星，在太阳型恒星和质量较小的恒星和一些最奇特的和令人费解的富含金属的恒星的能量耀斑。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致密气体云的分布图来了解伽马射线粒子的起源，切伦科夫望远镜阵列很快就会观测到这种粒子。最后，我们的目标是了解椭圆星系和透镜状星系是如何通过吸积其他卫星星系而生长的，通过深入研究它们的恒星外围的性质，这些事件的记录仍然保存着。
