G. Fabbiano, M. Elvis, A. Accomazzi +46
We write in response to the call from the 2020 Decadal Survey to submit white papers illustrating the most pressing scientific questions in astrophysics for the coming decade. We p…
Infrared observations of the 2006 outburst of the recurrent nova RS Ophiuchi: the early phase
A. Evans, T. Kerr, Bin Yang +20
We present infrared spectroscopy of the recurrent nova RS Ophiuchi, obtained 11.81, 20.75 and 55.71 days following its 2006 eruption. The spectra are dominated by hydrogen recombin…
Major Scientific Challenges and Opportunities in Understanding Magnetic Reconnection and Related Explosive Phenomena in Solar and Heliospheric Plasmas
