NASA's Kepler spacecraft has observed superflares

NASA's Kepler spacecraft has observed superflares on Sun-like stars thousands of times larger than the solar flares produced by our own Sun. Brad Schaefer points out that a similar superflare on our Sun could have disastrous consequences for us on Earth. Two 2000 papers by Schaefer suggested that superflares could be caused by interactions of stellar magnetic field lines with nearby planets, although this is not confirmed by the recent Kepler observations.

International Conference Held In Honor of Roy P. Daniels Professor and LSU Distinguished Research Master Jerry P. Draayer

International Conference Held In Honor of Roy P. Daniels Professor and LSU Distinguished Research Master Jerry P. Draayer

More than 100 people, including some of the most prominent scientists from the U.S. and abroad, paid tribute to Draayer's world-wide recognized research and academic achievements, honored during Horizons of Innovative Theories, Experiments, and Supercomputing in Nuclear Physics, or HITES 2012, international conference held June 4 - 7 in the historic New Orleans French Quarter. The conference opening speech was offered by Prof. Michael Cherry (Chair, Department of Physics & Astronomy, LSU), and the meeting was closed by the director of Oak Ridge National Lab (ORNL) Physics Division Dr. David Dean. Many Draayer's colleagues from LSU, LA Board of Regents, and Southeastern Universities Research Association (SURA), as well as family members joined the celebratory ceremony in his honor. The closing speech was offered by Dean Kevin Carman, Dean of LSU's College of Basic Sciences, who acknowledged Draayer's contribution to our university.

Studying the Fundamental Properties of Neutrinos

Studying the Fundamental Properties of Neutrinos

Profs. Thomas Kutter, Martin Tzanov and William Metcalf (Emeritus) are studying the fundamental properties of neutrinos, the most ghostly and numerous of the basic building blocks of nature. Along with a LSU based team consisting of post-docs (Oleg Perevozchikov, Jonathan Insler, Flor Blaszcyk) and students (Jeremiah Haremza, Corey Myers) they perform this research in Japan, where their experiment is located. Their recent paper describing a new type of neutrino oscillations, that is the transformation of one type (or flavor) of neutrino into another has recently been selected by the French popular science magazine La Recherche (the French equivalent of Scientific American) for an award amongst many outstanding papers in all fields of science.

IDC Announces New Winners of HPC Innovation Excellence Awards

IDC Announces New Winners of HPC Innovation Excellence Awards

A talk presented by Wayne Newhauser at the 2012 International Supercomputing Conference (ISC 12) in Hamburg, Germany was awarded an HPC Innovation Excellence Award. The paper described clinical trials performed via computer simulation "that would have been prohibitively expensive and taken longer to conduct with traditional methods." The joint LSU-Mary Bird Perkins Cancer Center program "compared the effectiveness of multiple therapy options leading to better-informed clinical decisions" and resulting in estimated savings of over $100M in infrastructure and research costs.

Grad student reaches stars

Grad student reaches stars

n January, LSU astronomers published a solution to a long-standing fundamental problem of astrophysics: what produces thermonuclear, or Type Ia, supernovae, which are tremendous explosions where the light is often brighter than a whole galaxy? LSU Professor of Physics & Astronomy Bradley Schaefer and graduate student Ashley Pagnotta have proven that these supernovae are caused by a pair of white dwarf stars. Their research was featured in Nature, one of the most prestigious scientific journals in the world, considered quite a feat for a graduate student. But then, Pagnotta is no average student.

Halo Nucleus Be11: A Spectroscopic Study via Neutron Transfer

Halo Nucleus Be11: A Spectroscopic Study via Neutron Transfer

A research team, led by a group from the Univ. of Tennessee and including Jeff Blackmon and Milan Matos from LSU, has elucidated the puzzling properties found in nearly pure neutron matter surrounding a short-lived atomic nucleus of beryllium. The "neutron halos" were produced in experiments at Oak Ridge National Laboratory in nuclei with 2 more neutrons than normal beryllium. The results show how the unusual properties of these halos originate from a mixing of a single neutron between two different quantum mechanical states.

LSU Team Wins NASA Robert H. Goddard Exceptional Achievement Outreach Award

LSU Team Wins NASA Robert H. Goddard Exceptional Achievement Outreach Award

A team at LSU has won a NASA Robert H. Goddard Exceptional Achievement Outreach award for the development of the Wallops Ballooning Experience for Educators (WBEE) program. WBEE was based upon the highly successful LaACES program, but adapted into a one week workshop for high school teachers. The first WBEE workshop was conducted during the summer of 2011 for 30 teachers from across the country. One of these teachers, Mark Arseneault from Zachary High School, then led a group of high school students to develop their own balloon payload which flew as part of the LaACES launch expedition in May 2012. The second WBEE will be held during July 2012. LSU personnel who participated in the WBEE program and received the NASA award include Brad Ellison, Jim Giammanco, Doug Granger, Greg Guzik, Steven Summerville, and John Wefel.
