Title: The 2D Distribution of Iron Rich Ejecta in the Remnant of SN 1885 in M31 Authors: Robert A. Fesen, Peter Hoeflich, Andrew J.S. Hamilton First Author’s Institution: Dartmouth College Paper Status: Submitted to The Astrophysical Journal Supernova 1885 In August of 1885, a powerful supernova erupted in our neighboring galaxy, Andromeda. Astronomers name supernovae by […]
There are arguably a lot of things defy categorization, but it’s not everyday that we find something that suggests we do away with our categories altogether. The authors of today’s paper believe that the recently-discovered Type II supernova ASASSN-13co — read that as “assassin”, please — might just be one of the latter.
How do the most massive stars explode? A new model of massive stars predicts new observational evidence.
How does a massive star’s rotation affect the properties of its eventual explosion?
Some GRB-SNe pairs show interesting correlations across their light curves.
Spectra from the light echoes of distant supernovae can be used to probe the three dimensional structure of these massive and poorly-understood explosions.
Archival data are able to place constraints on the origin of supernova 2011fe.
By examining their expansion rate over time, Type II supernovae provide a way to measure extragalactic distances.
There might be more information in the Hubble diagram of supernovae than we first thought. Far away supernovae are subject to gravitational lensing and in the upcoming decades, they could be used to determine how much matter there is in the Universe and how it clusters.
This month’s undergraduate research post features pulsars as a probe of our galaxy’s magnetic field, and the possibility of asymmetries in supernovae associated with gamma-ray bursts.
