Abstract

Among the main science cases that have motivated the proposal of CUBES, a new high-resolution spectrograph for the Very Large Telescope at the European Southern Observatory, there is the study and the characterisation of the nucleosynthesis of beryllium. Classical novae have been proposed since the ’70s as one of the main factories of lithium in the Galaxy, but this hypothesis has been demonstrated on empirical basis only recently thanks to the direct identification of lithium in V1369 Cen and through the observations of the resonance transition of \(^{7}\)Be II, the \(^{7}\)Li parent, at 313.0 nm in the near-UV range. CUBES is then the ideal instrument to quantify the amount of \(^{7}\)Be and therefore of \(^{7}\)Li produced by the different novae types hosted in the different components of the Milky Way and also in its nearby satellite galaxies. As important by-product of high resolution spectroscopic observations obtained with CUBES, there are the study of the properties of nova ejecta abundances, the shocks evolution in novae and their connection with the high-energy emission observed in these transients, from satellites as Fermi and Swift.

带有立方体的经典新星
欧洲南方天文台(European Southern Observatory)的甚大望远镜(甚大望远镜)配备了一种新的高分辨率光谱仪,在这些主要的科学案例中,有一项是对铍核合成的研究和表征。自70年代以来,经典新星就被认为是银河系中锂的主要工厂之一,但这一假设直到最近才在经验基础上得到证实,这要归功于在半人马座V1369中直接发现了锂,并通过对\(^{7}\) Li母星\(^{7}\) Be II在313.0 nm近紫外范围内的共振跃迁的观测。立方体是一个理想的仪器,可以量化在银河系的不同组成部分及其附近的卫星星系中不同类型的新星产生的\(^{7}\) Be和\(^{7}\) Li的数量。作为用CUBES获得的高分辨率光谱观测的重要副产品,研究了新星喷出物丰度的特性,新星中的冲击演化及其与这些瞬态中观测到的高能发射的关系,这些瞬态观测来自Fermi和Swift卫星。

期刊介绍: Many new instruments for observing astronomical objects at a variety of wavelengths have been and are continually being developed. Furthermore, a vast amount of effort is being put into the development of new techniques for data analysis in order to cope with great streams of data collected by these instruments. Experimental Astronomy acts as a medium for the publication of papers of contemporary scientific interest on astrophysical instrumentation and methods necessary for the conduct of astronomy at all wavelength fields. Experimental Astronomy publishes full-length articles, research letters and reviews on developments in detection techniques, instruments, and data analysis and image processing techniques. Occasional special issues are published, giving an in-depth presentation of the instrumentation and/or analysis connected with specific projects, such as satellite experiments or ground-based telescopes, or of specialized techniques.
