In this article I will briefly review the current status of radio observations of nearby supernovae and their remnants. This review will initially address observations of the radio light curves of nearby core-collapse supernovae, followed by a more detailed summary of recent Very Long Baseline Interferometric observations of the expansion of nearby supernovae and their remnants. These later sec...
متن کاملEvidence of nearby supernovae affecting life on Earth
Observations of open star clusters in the solar neighborhood are used to calculate local supernova (SN) rates for the past 510 million years (Myr). Peaks in the SN rates match passages of the Sun through periods of locally increased cluster formation which could be caused by spiral arms of the Galaxy. A statistical analysis indicates that the Solar System has experienced many large short-term i...

We consider the explosion of supernovae and the possible production of a variety of high energy transients by delayed black hole formation in massive stars endowed with rotation. Following the launch of a " successful " shock by the usual neutrino powered mechanism, the inner layers of the star move outwards, but lack adequate energy to eject all the matter exterior to the neutron star. Over a ...
متن کاملSupernovae and Neutrinos
A long-standing problem in supernova physics is how to measure the total energy and temperature of νμ, ντ , ν̄μ, and ν̄τ . While of the highest importance, this is very difficult because these flavors only have neutral-current detector interactions. We propose that neutrino-proton elastic scattering, ν + p → ν + p, can be used for the detection of supernova neutrinos in scintillator detectors. It...
