Towards Nebular Spectral Modeling of Magnetar-Powered Supernovae
Conor M. B. Omand, Anders Jerkstrand
Many energetic supernovae (SNe) are thought to be powered by the rotational-energy of a highly-magnetized, rapidly-rotating neutron star. The emission from the associated luminous…
On the Validity of Steady-State for Nebular Phase Kilonovae
Quentin Pognan, Anders Jerkstrand, Jon Grumer
The radioactively powered transient following a binary neutron star (BNS) merger, known as a kilonova (KN), is expected to enter the steady-state nebular phase a few days after mer…
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…
Superluminous supernova 2015bn in the nebular phase: evidence for the engine-powered explosion of a stripped massive star
M. Nicholl, E. Berger, R. Margutti +25
We present nebular-phase imaging and spectroscopy for the hydrogen-poor superluminous supernova SN 2015bn, at redshift z=0.1136, spanning +250-400 d after maximum light. The light…
Long-duration superluminous supernovae at late times
A. Jerkstrand, S. J. Smartt, C. Inserra +13
Nebular-phase observations and spectral models of Type Ic superluminous supernovae are presented. LSQ14an and SN 2015bn both display late-time spectra similar to galaxy-subtracted…
Late-time spectral line formation in Type IIb supernovae, with application to SN 1993J, SN 2008ax, and SN 2011dh
A. Jerkstrand, M. Ergon, S. J. Smartt +5
We investigate line formation processes in Type IIb supernovae (SNe) from 100 to 500 days post-explosion using spectral synthesis calculations. The modeling identifies the nuclear…
