| תקציר: | Observing Supernovae (SNe) shortly after they explode is key to probing the final stages of their progenitor demise and its properties. Recent studies have shown that the majority of core-collapse SNe explode within a distribution of circumstellar material (CSM), ejected by the progenitor star in processes yet to be understood.
By studying the nearby decadal SN2023ixf, we developed a framework mapping this CSM based on panchromatic observations. UV-optical observations track the inner confined and dense CSM following the SN luminosity and tracking the CSM narrow lines. Later, the shock moves onto thinner extended CSM wind, where X-rays can be observed, mapping thinner parts of the CSM. Thus, we can map the distribution of CSM above the exploding star.
In this talk, I will present this framework and discuss how it can be expanded to more distant SNe, to gather statistics on the distribution of CSM around dying stars. |
