Late Spectral Evolution of the Ejecta and Reverse Shock in SN1987A
Claes Fransson, Josefin Larsson, Jason Spyromilio +10
We present observations with VLT and HST of the broad emission lines from the inner ejecta and reverse shock of SN 1987A from 1999 until 2012 (days 4381 -- 9100 after explosion). W…
The morphology of the ejecta in Supernova 1987A: a study over time and wavelength
Josefin Larsson, Claes Fransson, Karina Kjaer +9
We present a study of the morphology of the ejecta in Supernova 1987A based on images and spectra from the HST as well as integral field spectroscopy from VLT/SINFONI. The HST obse…
