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…
High resolution spectroscopy of the line emission from the inner circumstellar ring of SN 1987A and its hot spots
Per Groeningsson, Claes Fransson, Peter Lundqvist +8
We discuss high resolution VLT/UVES observations (FWHM ~ 6 km/s) from October 2002 (day ~5700 past explosion) of the shock interaction of SN 1987A and its circumstellar ring. A neb…
Infrared Integral Field Spectroscopy of SN 1987A
Karina Kjaer, Bruno Leibundgut, Claes Fransson +3
SN 1987A in the Large Magellanic Cloud is close enough for a study of the very late time evolution of a supernova and its transition to a supernova remnant. Nearly two decades afte…
SN 1987A at the end of its second decade
Karina Kjaer, Per Groeningsson, Rubina Kotak +2
After nearly two decades at least five emission mechanisms can be found in SN 1987A. The ejecta continue to glow as a result of the radioactive decay of long-lived nuclei (mostly 4…
