Simulated the XRISM observations of the iconic supernova remnant SN1987 A. The study: “Probing Shocked Ejecta in SN 1987A: A novel diagnostic approach using XRISM−Resolve” of V. Sapienza (UNIPA/OAPA) accepted on ApJL

SN1987 A is one of the most significant objects for studying supernova explosions and their remnants. This is because it is the only core-collapse supernova that has occurred relatively close to us (approximately 170000 light-years away, in the Large Magellanic Cloud) in the modern epoch. Therefore, it is the sole object of this type for which we have telescope observations

Predictions on the observability of the neutron star in SN1987A. The study: “Investigating the Time Evolution of the Thermal Emission from the Putative Neutron Star in SN 1987A for 50+ Years” of A. Dohi (Kyushu University) appeared on ApJ

SN1987A, located in the Large Magellanic Cloud, is an object of great importance for the study of supernovae and supernova remnants. In fact, it is the only supernova that has occurred recently and is close enough to allow us to obtain detailed observations across the entire electromagnetic spectrum. SN1987A was a core-collapse supernova, resulting from the collapse of the core

The magnetic field in SN1987A revealed from radio observations. The study: “Polarized radio emission unveils the structure of the pre-supernova circumstellar magnetic field and the radio emission in SN1987A” of O. Petruk (INAF-OAPA) appeared on A&A

Without any doubts, the supernova remnants SN1987A is the one that taught us more about this class of objects and supernova exposions. Produced by a supernova exploded in the Large Magellanic Cloud on February 23rd 1987, this is the only case in which we have observations of the progenitor, of the supernova explosion, and in which we follow the development

Confirmed the existence of a neutron star in the center of SN1987A. The paper: “Additional Evidence for a Pulsar Wind Nebula in the Heart of SN 1987A from Multiepoch X-Ray Data and MHD Modeling” of E. Greco (University of Amsterdam; INAF-OAPA) recently appeared on Apj

SN1987A, the supernova exploded in the Large Magellanic Cloud (at about 170000 light years of distance) on February 23rd 1987, was an iconic event for the study of supernovae and supernova remnants. In fact, it is the only case where it was possible to observe (with telescopes) the explosion and to follow with periodic observations the evolution of the supernova

An aspherical explosion to explain SN 1987 A properties. The study “Matter Mixing in Aspherical Core-collapse Supernovae: Three-dimensional Simulations with Single Star and Binary Merger Progenitor Models for SN 1987A” of M. Ono (Astrophysical Big Bang Laboratory) recently appeared on ApJ

A supernova exploded on 1987 February 23rd in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. Being at a distance of “only” 170000 light years from us, this supernova, named SN 1987 A, is the closest supernova exploded in the modern era, and thus it is a template to understand the physics of supernova explosions and the
