These data sets will contain numerous events detected very early in their evolution, shortly after explosion. In a recent <a href=\"https:\/\/dx.doi.org\/10.1093\/mnras\/stx2093\">study<\/a>, a team around&nbsp;Ulrich N\u00f6bauer from the Max Planck Institute for Astrophysics, including PSO researcher Markus Kromer, used numerical simulations to calculate synthetic observables for a number of different explosion models, specifically focusing on the first few days after explosion. They show that overall the early light curve evolution is similar for most of the investigated models. Characteristic imprints are induced by radioactive material located close to the surface. However, these are very similar to the signatures expected from ejecta\u2013CSM or ejecta\u2013companion interaction. Apart from pure deflagration explosion models, none of the synthetic light curves exhibit the commonly assumed power-law rise. They demonstrate that this can lead to substantial errors in the determination of the time of explosion.<\/p>\n\n\n\n<p>Publication: U. M. Noebauer, M. Kromer, S. Taubenberger, P. Baklanov, S.
