The envelope thickens

TL;DR: In this paper, it is concluded that the expected optical echo from the cloud should be resolvable and this, rather than an internal energy source, may cause the observed slowdown in dimming of the supernova.

TL;DR: The detection of a pulsar a l'interieur de la supernova SN 1987 A laisse apparaitre des proprietes tout a fait etonnantes: une periode d'une demi-milliseconde and la presence d'un compagnon jusqu'alors inconnu en orbite de 8 heures autour du pulsar as mentioned in this paper.

TL;DR: In this paper, a gaussian line profile gives an acceptable fit to the 1238 keV line and the measured linewidth is a factor of about two greater than model predictions, although the discrepancy represents only two standard deviations.

TL;DR: In this article, the mass, location and nature of the emitting dust from SN1987A have been discussed, and it was shown that the dust grains cannot have formed in the ejecta of the supernova, nor do they appear to be symmetrically distributed about it; rather, they are located at a distance of about 1 light year from, and mostly behind, the SO.
