nova
any sudden brightening of a previously inconspicuous star
Star that suddenly erupts into an object of great brilliance, surpassing the Sun's luminosity by a factor of hundreds of thousands to millions of times and then fading more slowly
A star that abruptly and temporarily increases its brightness by a factor of hundreds of thousands Unlike supernovae (much more violent explosions which destroy the stars that produce them), stars that "go nova'' can do so more than once Novae are thought to occur in binary stars in which one member is a compressed dwarf star (such as a white dwarf or a neutron star) orbiting close to a much larger star According to this theory, material from the larger star's outer layers accumulates on the dwarf's surface, becoming ever hotter and more compressed by the dwarf's strong gravity, until the ~stolen'' material explodes [See supernova, binary star, white dwarf, and neutron star]
an object that greatly increases in brightness rapidly, so it appears as a ``new star'' It is caused by the buildup on a white dwarf's surface of hydrogen gas from a companion star to the point where the hydrogen fuses explosively into helium The super-rapid fusion does not blow up the white dwarf, so the process can repeat itself (contrast with a Type I supernova)
A star which suddenly becomes many times brighter than previously, and then gradually fades
A star that flares up to several times its original brightness for some time before returning to its original state
A new star, usually appearing suddenly, shining for a brief period, and then sinking into obscurity
a star that ejects some of its material in the form of a cloud and become more luminous in the process
A star that abruptly increases in brightness by a factor of a million A nova is caused in a binary star system where hydrogen-rich material is transferred to the surface of a white dwarf until sufficient material and temperatures exist to kindle explosive nuclear fusion
An explosion on the surface of a binary star because of a chain reaction
A star that explodes, temporarily increasing its brightness 100000 or more
A "new" star or a very old dying star A sudden brightening of a star making it appear "new" in the sky; believed associated with eruptions on white dwarfs in binary systems Observations can help us understand what a nova is
A star that suddenly and temporarily brightens, thought to be due to new material being deposited on the surface of a white dwarf
A star which suddenly flares up to many times its original brightness before fading again
A type of suddenly brightening star (from the Latin for ``new'') resulting from explosive brightening when gas is dumped from one member of a binary star pair onto the other
NGO: Vietnam/Australian Program, AusAID
An existing star which suddenly increases its brightness by more than 10 magnitudes and then slowly fades O
= 1 'Mech Star and 1 infantry Star (5 'Mechs 25 Elementals) Supernova =1 'Mech Binary and 2 infantry Stars (10 'Mechs 50 Elementals)
A star which, from natural causes, experiences a sudden increase in brightness Stars experiencing an explosive increase are called supernovas
