Title: The E-Nova Project: A Multi-Wavelength Initiative to Probe the Ejecta and Environments of Novae
Speaker: Laura Chomiuk, Michigan State University
Abstract: When imagining a nuclear explosion, we often picture strong, spherical shock waves, like a bomb or supernova; however, nature's most common thermonuclear explosions look nothing like this, showing delayed and multiple phases of mass ejection that can last for months after the nuclear fuel is ignited. These most common explosions are novae---thermonuclear runaways on the surfaces of accreting white dwarfs---and their complexities are best revealed with an intensive multi-wavelength observational program highlighting radio and X-ray data---our E-Nova Project. I will discuss our recent results, featuring observations from the Karl G. Jansky Very Large Array, and spotlighting sources like recent novae with giant companions and novae that have recently been detected in GeV gamma rays (an emission process that was not predicted and remains an intriguing mystery).
