The matter beyond the ring: the recent evolution of SN 1987A observed by the Hubble Space Telescope
J. Larsson, C. Fransson, D. Alp +14
The nearby SN 1987A offers a spatially resolved view of the evolution of a young supernova remnant. Here we precent recent Hubble Space Telescope imaging observations of SN 1987A,…
Three-dimensional distribution of ejecta in Supernova 1987A at 10 000 days
J. Larsson, C. Fransson, J. Spyromilio +19
Due to its proximity, SN 1987A offers a unique opportunity to directly observe the geometry of a stellar explosion as it unfolds. Here we present spectral and imaging observations…
SN 2012aa - a transient between Type Ibc core-collapse and superluminous supernovae
R. Roy, J. Sollerman, J. M. Silverman +21
Context: Research on supernovae (SNe) over the past decade has confirmed that there is a distinct class of events which are much more luminous (by mag) than canonical core-…
Long-rising Type II supernovae from PTF and CCCP
F. Taddia, J. Sollerman, C. Fremling +17
Supernova (SN) 1987A was a peculiar H-rich event with a long-rising (LR) light curve (LC), stemming from a compact blue supergiant star (BSG). Only a few similar events have been p…
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…
Metallicity at the explosion sites of interacting transients
F. Taddia, J. Sollerman, C. Fremling +8
Context. Some circumstellar-interacting (CSI) supernovae (SNe) are produced by the explosions of massive stars that have lost mass shortly before the SN explosion. There is evidenc…
