Discovery of molecular hydrogen in SN 1987A
Claes Fransson, Josefin Larsson, Jason Spyromilio +3
Both CO and SiO have been observed at early and late phases in SN 1987A. H_2 was predicted to form at roughly the same time as these molecules, but was not detected at early epochs…
The diversity of Type II supernova versus the similarity in their progenitors
S. Valenti, D. A. Howell, M. D. Stritzinger +19
High-quality collections of Type II supernova (SN) light curves are scarce because they evolve for hundreds of days, making follow-up observations time consuming and often extendin…
The Destruction of the Circumstellar Ring of SN 1987A
Claes Fransson, Josefin Larsson, Katia Migotto +23
We present imaging and spectroscopic observations with HST and VLT of the ring of SN 1987A from 1994 to 2014. After an almost exponential increase of the shocked emission from the…
Constraints on explosive silicon burning in core-collapse supernovae from measured Ni/Fe ratios
A. Jerkstrand, F. X. Timmes, G. Magkotsios +7
Measurements of explosive nucleosynthesis yields in core-collapse supernovae provide tests for explosion models. We investigate constraints on explosive conditions derivable from m…
X-ray illumination of the ejecta of Supernova 1987A
J. Larsson, C. Fransson, G. Östlin +25
We present the late-time optical light curve of the ejecta of SN 1987A measured from HST imaging observations spanning the past 17 years. We find that the flux from the ejecta decl…
