新星的射电研究：现状报告和新结果的亮点
Radio studies of novae: a current status report and highlights of new results
摘要：
新星，是一种在吸积中的白矮星表面由失控的热核燃烧所引发的视觉上的突然变亮，是相当常见和明亮的事件。尽管它们作为研究核燃烧和吸积现象的附近实验室具有天文学意义，但这些常见恒星爆炸的许多方面在观测上没有很好的约束，并且仍然知之甚少。无线电观测、建模和解释可能在解决其中一些令人困惑的问题方面发挥关键作用。在这篇综述中，我们着重讨论了利用射电观测来检验和改进新星模型的可能性，并对观测前沿和理论发展的现状进行了报告。我们具体解决的问题，喷出物的质量，多相和复杂的喷射现象，以及周围的新星密集的环境的影响的准确估计。随着新的观测结果的亮点，我们说明了无线电观测如何揭示这些长期存在的难题。
英文摘要：
Novae, which are the sudden visual brightening triggered by runaway thermonuclear burning on the surface of an accreting white dwarf, are fairly common and bright events. Despite their astronomical significance as nearby laboratories for the study of nuclear burning and accretion phenomena, many aspects of these common stellar explosions are observationally not well-constrained and remain poorly understood. Radio observations, modeling and interpretation can potentially play a crucial role in addressing some of these puzzling issues. In this review on radio studies of novae, we focus on the possibility of testing and improving the nova models with radio observations, and present a current status report on the progress in both the observational front and theoretical developments. We specifically address the issues of accurate estimation of ejecta mass, multi-phase and complex ejection phenomena, and the effect of a dense environment around novae. With highlights of new observational results, we illustrate how radio observations can shed light on some of these long-standing puzzles.
