Novae reaching first or second magnitude occur only several times per century. Most are found telescopically, perhaps only one every year to eighteen months reaching naked-eye visibility. They occur far more frequently than galactic supernovae, averaging about ten per year. Novae most often occur in the sky along the path of the Milky Way, especially near the observed galactic centre in Sagittarius however, they can appear anywhere in the sky. Recurrent nova processes are the same as the classical nova, except that the fusion ignition may be repetitive because the companion star can again feed the dense atmosphere of the white dwarf. A few novae produce short-lived nova remnants, lasting for perhaps several centuries. This atmosphere is mostly hydrogen and is thermally heated by the hot white dwarf, which eventually reaches a critical temperature causing rapid runaway ignition by fusion.įrom the dramatic and sudden energies created, the now hydrogen-burnt atmosphere is then dramatically expelled into interstellar space, and its brightened envelope is seen as the visible light created from the nova event, and previously was mistaken as a "new" star. When the orbital period falls in the range of several days to one day, the white dwarf is close enough to its companion star to start drawing accreted matter onto the surface of the white dwarf, which creates a dense but shallow atmosphere. They are likely created in a close binary star system consisting of a white dwarf and either a main sequence, sub-giant, or red giant star. Also with similar names are the much more energetic supernovae (SNe) and kilonovae.Ĭlassical nova eruptions are the most common type of nova. Luminous red novae share the name and are also cataclysmic variables, but are a different type of event caused by a stellar merger. They are all considered to be cataclysmic variable stars.
The main sub-classes of novae are classical novae, recurrent novae (RNe), and dwarf novae. All observed novae involve closely located binary stars (the progenitors), either a pair of red dwarfs in the process of merging, or a white dwarf and another star. Novae involve an interaction between two stars that cause the flareup that is perceived as a new entity that is much brighter than the stars involved.Ĭauses of the dramatic appearance of a nova vary, depending on the circumstances of the two progenitor stars. Wikipedia (5.00 / 1 vote) Rate this definition:Ī nova (plural novae or novas) or classical nova (CN, plural CNe, or Q) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star, that slowly fades over several weeks or many months.
