A team of UW researchers has determined a more precise solar neutrino production figure, finding that the fusion rate is 17% greater than previously estimated. This new finding means the sun must be producing 17% more energetic neutrinos, with an accuracy of 3-4 percentage points.
Researchers at Texas A&M University have made a precise measurement of solar neutrinos, resolving a long-standing puzzle. By studying the proton transfer reaction, they found that the number of solar neutrinos is lower than expected by around 20 percent compared to previous calculations.
Dana Longcope, a Montana State University physicist, has received the Presidential Early Career Award for Scientists and Engineers. He was recognized for his work on modeling the sun's magnetic fields, which helps explain solar flares and coronal mass ejections that affect Earth's technology.
Loren Acton, a former astronaut and solar physicist, has won the prestigious George Ellery Hale Prize for his outstanding contributions to solar astronomy. Acton's research focuses on understanding the Sun's behavior, shapes, colors, and motions.
Raymond Davis Jr.'s groundbreaking work on detecting solar neutrinos led to a significant discovery of the sun's energy production and sparked ongoing investigations into the cause of the solar neutrino deficit. Masatoshi Koshiba's contributions to neutrino astronomy with his Kamiokande detectors also earned him the Wolf Prize.
Scientists at NASA's Marshall Space Flight Center have accurately predicted the current phase of Cycle 23 of the sunspot cycle. The team predicts that Cycle 23 will be above average but not a record setter, with the sun now on the upswing of its 23rd activity cycle.
The UNC-CH physics and astronomy department has launched a new program called SOLAR, which allows North Carolina public school teachers and students to use and remotely control the Morehead Observatory telescope. The program offers students access to real scientific data and the opportunity to capture their own images of the universe.
Researchers John H. Thomas and Benjamin Montesinos present a more realistic version of the siphon-flow model, predicting how gas flows from sunspots into the solar atmosphere. Their results match observations in considerable detail, shedding light on astrophysical processes involving strong magnetic fields and jets of gas.
