👉 Nova fluid, also known as nova ejecta or circumstellar material, is the material expelled during a nova explosion, a cataclysmic event in binary star systems where a white dwarf accretes hydrogen-rich material from its companion star. This material forms a dense, rapidly expanding envelope around the white dwarf, consisting primarily of hydrogen and helium, along with heavier elements. The nova fluid undergoes a series of complex physical and chemical processes, including ionization, heating, and cooling, leading to the emission of intense radiation across various wavelengths. This dynamic environment is crucial for understanding the evolution and behavior of novae, as well as the chemical enrichment of their surrounding space.
