Supernova Explosions: Lessons from Spectropolarimetry

Supernova can be polarized by an asymmetry in the explosion process, an off-center source of illumination, scattering in an envelope distorted by rotation or a binary companion, or scattering by the circumstellar dust. Careful polarimetry is the most powerful tool to study the 3-D geometry of supernovae. A deep understanding of the 3-D geometry of SNe is essential in using them as calibrated di...

Eye injuries from car battery explosions.

CASE I An 18-year-old engineer was measuring the charge of a car battery which had been on overnight trickle charge, when there was a spark and the battery exploded, injuring his left eye. On examination the corrected visual acuity was found to be 6/4 R and 6/24 L. There was an extensive acid burn of the left conjunctiva and cornea and a secondary uveitis. Intraocular pressure was 37 mm/Hg. The...

GRAVITATIONAL RADIATION FROM SUPERNOVA EXPLOSIONS * Ronald

As a simple model of a supernova explosion we study a point mass exploding into two equal point masses moving back to back at high velocity, or a superposition of such elementary explosions. We employ two calculational methods. In one method we assume an infinite acceleration for zero time and calculate the gravitational field and the distribution of emitted energy. A cutoff frequency in the po...

From nuclear multifragmentation reactions to supernova explosions

In this talk I discuss properties of hot stellar matter at sub-nuclear densities which is formed in supernova explosions. I emphasize that thermodynamic conditions there are rather similar to those created in the laboratory by intermediate-energy heavy-ion collisions. Theoretical methods developed for the description of multi-fragment final states in such reactions can be used also for descript...
