FH Serpentis
FH Serpentis (FH Ser) was a nova that appeared in the constellation Snake in 1970 . FH Serpentis achieved a maximum apparent magnitude of 4.4 mag visually and is approximately 3,000 light years (950 pc ) from Earth . The name part "FH" follows the rules for naming variable stars and states that FH Serpentis is the 172nd variable star discovered in the constellation Snake.
meaning
FH Ser has been called " Rosetta stone of nova energetics " - " Rosetta stone of the Nova Physics " ( Gallagher , designated in 1977) because the observations of this Nova over a wide wavelength range maintained, showed that a nova outburst is much more complex than previously was accepted through observation of "classical" novae.
FH Ser was one of the first novae to be observed in the optical, far ultraviolet , far infrared, and radio wave ranges at the same time . These observations led to the discovery of unexpected phenomena such as B. the maximum in the infrared 100 days after the outbreak (a property that may be common in other novae with similar light curves) or the constancy of the bolometric luminosity for the first two months after the optical maximum.
