FH Serpentis

FH Serpentis (FH Ser) was a Nova, which appeared in 1970 in the constellation of the Serpent. FH Serpentis reached a maximum in the visual apparent magnitude of 4.4 mag and is about 3,000 light- years ( 950 pc) away from us. The name part " FH" follows the rules for naming variable stars and states that FH Serpentis is the 172te variable star, which was discovered in the constellation of the Serpent.

Importance

FH Ser was identified as " the Rosetta stone of nova energetics " - called " Rosetta Stone of the Nova Physics" ( Gallagher 1977), because the observations of this Nova over a wide wavelength range aufzeigten that a nova outburst is much more complex than previously was adopted by observations of "classical" novae.

FH Ser was one of the first supernovae, which was also observed in the optical, far ultraviolet, far-infrared and radio waves. These observations led to the discovery of unexpected phenomena, such as the maximum in the infrared 100 days after outburst ( a property that may be in other novae common with similar light curves ) or the constancy of the bolometric luminosity for the first two months after the optical maximum.
