Research News: Graduate student Alison Dreyfuss' work on the Hoyle State
in 12C is featured in the most recent edition of The Pursuit, the College of
Science's news magazine. The Hoyle State was originally proposed in 1954 by
Fred Hoyle as an excited state of 12C as a key step in stellar
nucleosynthesis. Dreyfuss, working with Kristina Launey, used a new nuclear structure model (the No-Core Symplectic Model) developed at LSU to provide the first detailed explanation of the physics responsible for the Hoyle
State, published in Physics Letters B. More news...
In a paper entitled "Lorentz transformation of blackbody radiation" (Phys. Rev. E 88, 044101, 2013), G. W. Ford and Robert O'Connell have solved a problem which numerous authors have worked on over a time span exceeding a hundred years. This is the question of how temperature behaves under a Lorentz transformation. Both Einstein in 1907 and Planck in 1908 published results which disagreed with each other and both of which proved to be incorrect. The reason why the problem remained unsolved for so many years was the fact that no experimental evidence existed to provide a check on the huge variety of theoretical methods employed. By constrast, Ford and O'Connell employed the experimental results for the spectrum of the universal cosmic blackbody radiation measured by Earth observers who are in different reference frames because of their motion through the 2.7K radiation. Despite the fact that kT behaves like an energy, it turns out that T does not change in a Lorentz transformation. More news...
The Landolt Standards and 21st Century Photometry meeting will be held here at LSU, Tuesday, May 19 - Thursday, May 21, 2015. The conference will celebrate the career of Dr. Arlo Landolt. Arlo Landolt is a Ball Family Professor Emeritus with the Department of Physics & Astronomy at Louisiana State University.
