Jasność Słońca




Jasność Słońca – używana w astronomii pozaukładowa jednostka miary używana do określania jasności gwiazd. Równa się obecnej jasności bolometrycznej Słońca:



1L⊙=3,827×1026W{displaystyle 1,L_{odot }=3,827times 10^{26},{hbox{W}}}{displaystyle 1,L_{odot }=3,827times 10^{26},{hbox{W}}}.

Określa ona moc promieniowania elektromagnetycznego Słońca we wszystkich zakresach fal, nie tylko widzialnym. Jasność Słońca podlega pewnym zmianom w trakcie cyklu słonecznego, ale są one małe w porównaniu ze średnią wartością[1].
