MAST has begun to post some research results!
1) I have started to do some dripping handrail models of accretion disks. You can find them here: http://www.madscitech.org/csg/accretion.html
2) James Firmiss and I have begun serious work on neutron star equations of state, results will be put up shortly.
3) Chris Winfield is giving a talk on local solvability at the American Mathematical Society meeting in New Orleans, that talk is located here: http://www.madscitech.org/csg/AMS10mintalk.pdf
4) We are doing research and development of database capabilities in Mathematica, mostly due to the efforts of Rocky Wenz.
More results will be reported as they occur!

Recent Papers of Interest 16 November 2010
Here are some ArXiv papers I found interesting of late.
1) Takami Kuroda and Hideyuki Umeda, Three Dimensional Magneto Hydrodynamical Simulations of Gravitational Collapse of a 15Msun Star
This is an important paper for those of us who study compact objects. It begins with a nice overview of the theory of core-collapse supernovae (CCSN) and the efforts to model these. The next two sections details the code used, both MHD and GR. This is followed by the adaptive mesh scheme used. Finally they discuss the tests of the code. This accounts for half of the paper and makes a very nice overview of modeling MHD in a GR environment. The results are very nice, great paper!
2) Manjit Bhatia, P. Narayana Swamy, Elementary Quantum Mechanics in a Space-time Lattice
This paper explores the particle-in-a-box problem under the assumption of a fundamental length scale forming a spacetime lattice. This is an interesting approach.
3) Oleg Korobkin, Ernazar B. Abdikamalov, et al, Stability of general-relativistic accretion disks,
This paper is a thorough treatment of a model of unstable accretion disks near a black hole.
4) T. Fischer, I. Sagert, et al, The revival of an explosion mechanism of massive stars - the quark hadron phase transition during the early post bounce phase of core collapse supernovae,
This is a long paper (30 pages) explores the bounce during a supernova core collapse caused by the so-called quark hadron phase transition. The introduction is a nicce overview of the topic and its history. The second section, no pun intended, forms the theoretical core of the paper, describing the hybrid equation of state and other issues. The third section describes the simulation scheme. The fourth section explores the results of the model runs. The conclusion is that the quark matter description leads to early onset of deconfinement, a quark-gluon plasma. A very interesting paper!
