天体物理学家越来越多地考虑到轨道伴星对恒星演化的影响。新的发现突显了双星相互作用在一系列天体物理事件中的作用，包括一些以前被解释为独一无二的单星演化。我们回顾了经典的双星现象，如Ia型超新星，并讨论了新的现象，如中等光度瞬变，产生引力波的双黑洞，以及恒星与其行星之间的相互作用。最后，我们根据包括单星和双星的解释，重新评估众所周知的现象，如发光的蓝色变星。同时，我们在双星演化的框架内对新的发现进行了背景分析。在过去的十年里，随着恒星观测的复杂性越来越多地被解释为单情景和双情景的相互作用，恒星天体物理学出现了复兴。在接下来的十年里，随着诸如平方公里阵列、詹姆斯·韦伯太空望远镜等大规模项目的到来，以及越来越复杂的计算方法，将看到一个扩展的恒星演化框架的诞生，它将在许多其他天体物理学领域产生影响，如星系演化和核合成。
Abstract Astrophysicists are increasingly taking into account the effects of orbiting companions on stellar evolution. New discoveries have underlined the role of binary star interactions in a range of astrophysical events, including some that were previously interpreted as being due uniquely to single stellar evolution. We review classical binary phenomena, such as type Ia supernovae, and discuss new phenomena, such as intermediate luminosity transients, gravitational wave-producing double black holes, and the interaction between stars and their planets. Finally, we reassess well-known phenomena, such as luminous blue variables, in light of interpretations that include both single and binary stars. At the same time we contextualise the new discoveries within the framework of binary stellar evolution. The last decade has seen a revival in stellar astrophysics as the complexity of stellar observations is increasingly interpreted with an interplay of single and binary scenarios. The next decade, with the advent of massive projects such as the Square Kilometre Array, the James Webb Space Telescope, and increasingly sophisticated computational methods, will see the birth of an expanded framework of stellar evolution that will have repercussions in many other areas of astrophysics such as galactic evolution and nucleosynthesis.
