ASTROPHYSICS RESEARCH: SUMMER 1995

HOT RESEARCH TOPICS!

Convection in Core-Collapse Supernovae

 John is working in a large collaboration on a study of postshock macro-convection in core collapse supernove.

Supernova Remnants at Shell Formation

Eric has finished a one dimensional simulation of the Sedov-Taylor shock with radiative cooling, and is preparing to do two dimensional simulations. Also in the works is an analysis of the data obtained from the one dimensional simulation.

High Mass X-ray Binaries

Michael Owen is currently working on including radiative transfer of x-rays in a 2D hydrodynamic simulation of an HMXB.

SN1987A: Blastwave Meets the Ring

John is modeling the expected impact of the blastwave from supernova SN1987A with the compact circumstellar ring observed around the SN by HST.

Astronomical Image Processing: SNR 3C396

Kristy Dyer is working on SNR 3C396

Data reduction of radiodata from SNR 3C397.

Areg spent his summer working on 3C397. As a result maps of radio intensity and polarization were received.

X-ray Spectra in Supernova Remnants

JayLyerly is coding like the wind to create x-ray spectra from SNR with non-equilibrium ionization. Also in the project is the variation of the ratio of electron temperature to ion temperature behind the shock front. The current model is a

Sod Shock MHD modelling

 Glen Double worked with Lee Bennett during the summer to explore a 1-d MHD Sod shock problem using Lee's hybrid code, and compare the results to those of Brio and Wu, J. Comp. Phys., Vol. 75, 400-422 (1988).
