SN 1978K is one of the X-ray rich supernova with long lasting X-ray emission in the recent times. SN 1978K was observed with XMM-Newton telescope in 2006 for 120ks. We present the X-ray spectral analysis of SN 1978K. The spectrum is best fit with a "dual vnei" model having variable elemental abundances. Our analysis shows the presence of two temperature plasma - one with a higher temperature and other with a lower temperature. We combine the X-ray analysis with the optical to study the evolution of velocity structure of the circumstellar medium. |
