Title: | 3D Hydrodynamic Modeling of SN 1987A from the SN explosion till the Athena Era | Authors: | ORLANDO, Salvatore Miceli, Marco PUMO, MARIA LETIZIA BOCCHINO, Fabrizio |
Issue Date: | 2015 | Volume: | Exploring the Hot and Energetic Universe: The first scientific conference dedicated to the Athena X-ray observatory | First Page: | 64 | Abstract: | The proximity of SN 1987A and the wealth of observations collected at all wavelength bands since its outburst allow us to study in detail the transition of a supernova (SN) in a supernova remnant(SNR) and the link between the morphological properties of a SNRand the complex phases in the SN explosion. Here we investigate theinteraction between the remnant of SN 1987A and the surroundingcircumstellar medium (CSM) through three-dimensional hydrodynamic modeling. The aim is to identify the imprint of SN 1987A on the X-ray emission of its remnant and to determine the contribution of shocked ejecta and shocked CSM to the detected X-ray flux, thusproviding clues on both the ejecta and the density structure of theinhomogeneous CSM. Our model describes the evolution of the blast wave from the breakout of the shock wave at the stellar surface till its transition from SN to SNR, making predictions on the future observations of SN 1987A with the instruments on board Athena. Our model is able to reproduce alltogether the main observables of both the progenitor supernova (e.g. the bolometric lightcurve during the first 250 days) and of its remnant (X-ray lightcurves and spectra during the following 26 years of evolution), providing for the first time an accurate description of the structure of ejecta and of the CSM around the progenitor. | Conference Name: | Exploring the Hot and Energetic Universe: The first scientific conference dedicated to the Athena X-ray observatory | Conference Place: | Madrid, Spain | Conference Date: | 8-10 September, 2015 | URI: | http://hdl.handle.net/20.500.12386/23383 | URL: | https://www.cosmos.esa.int/web/conferences-archive/athena-2015 | Bibcode ADS: | 2015eheu.conf...64O | Fulltext: | open |
