Supernova 1987A
First, I summarize the main points that we have learned about the interior of SN1987A. Then, I describe in greater detail the rapidly developing impact of SN1987A with its inner circumstellar ring.
متن کاملFifteen Years of High-Resolution Radio Imaging of Supernova 1987A
Supernova 1987A in the Large Magellanic Cloud provides a spectacularly detailed view of the aftermath of a core-collapse explosion. The supernova ejecta initially coasted outward at more than 10% of the speed of light, but in 1990 were observed to decelerate rapidly as they began to encounter dense circumstellar material expelled by the progenitor star. The resulting shock has subsequently prod...
متن کاملThe Physics of Supernova 1987A
We describe multiwavelength observations of the evolving spectra and images of Supernova (SN) 1987A, and we review the principles used to infer the physical conditions in the explosion debris. We interpret the early optical and gammaray light curves with a simple diffusion model. We review the evidence for dust formation in the debris. We show X-ray and optical observations that enable us to ch...
متن کاملThe Remnant of Supernova 1987A
Although it has faded by a factor of ∼107, SN 1987A is still bright enough to be observed in almost every band of the electromagnetic spectrum. Today, the bolometric luminosity of the debris is dominated by a far-infrared (∼200 μm) continuum from ∼0.5 M of dust grains in the interior debris. The dust is heated by UV, optical, and near-infrared (NIR) emission resulting from radioactive energy de...
متن کاملSupernova 2008d: a Repetition of Supernova 1987a in a Binary
The Supernova 2008D is similar to that of SN 1987Awithout the H-envelope. Soderberg et al. (2008) reported the serendipitous discovery of the SN2008D at the time of the explosion, accompanied by an X-ray outburst XRF080109. The central remnant, which we believe to be the black-hole (BH) central engine in the Blandford-Znajek mechanism, is estimated, on the basis of the 7% Ni production, to have...
