### Spectroscopic Study Of Light Curve And Physical Properties For SN2010jl

#### Abstract

Abstract:In this work, The physical properties were studies for ( supernova 2010jl) - which discovered on 2010 Nov. 3 - depending on (Oort Model ), optical spectrum curve and by applying special mathematical equations. The physical properties represented by explosion energy, initial velocity of ejecta, mass of ejecta, mass of 56Ni, distance from the earth, radius of ejecta, the momentum, expansion velocity and the age. Also, temperature of black body of SN2010jl during photospheric phase were calculated depending on data taken from optical spectrum curve and by applying special mathematical equation. The curve between temperature of black body and time in days were plotted, rang of temperature between (7300 °k – 9700 °k ) noticed.
