Physics Teacher Events & News
TEACHER IN SERVICE CREDITS:
LIPTA will provide you with a 3 hour CTLE certificate for attending our Fall Conference
SUNYSB will provide attendance certification for each of the lectures attended during the Fall 2017 semester. NYS teachers who wish to receive CTLE credit for any of these lectures must register HERE You must register for each lecture you attend and sign-in at the lecture. The Graduate School will send a CTLE certificate about six weeks after each lecture.
ASTRONOMY LECTURE at SUNYSB Friday 12-1-17, 7:30 PM ESS 001 Jim Lattimer "When Neutron Stars Collide: The Story of GW170817" The recent LIGO/VIRGO observation of gravitational waves from the merger of two neutron stars, and follow-up observations in gamma ray, X-rays, ultraviolet, optical, infrared, millimeter and radio radiation was the most intensively studied astronomical event of all time. These observations revealed that two approximately 1.4 solar mass neutron stars merged after being born in supernova explosions and orbiting each other for around 11 billion years, and in the process, created a short gamma-ray burst and ejected about 20,000 Earth masses of heavy elements into space. The merger occurred in a galaxy far, far, away, about 130 million light years distant. It seems likely that the remnant collapsed into a black hole within a second. The optical and infrared radiation observed for over a week following the merger likely originates from the radioactive decay of nuclei formed from ejected neutron star matter, which apparently solves the century-old mystery of the origin of half of elements heavier than iron, the so-called r-process elements, which include gold and platinum. This event also confirmed the association between short gamma-ray bursts and mergers.
