The spectroscopic evolution of the $\gamma$-ray emitting classical nova Nova Mon 2012. I. Implications for the ONe subclass of classical novae

S. N. Shore, I. De Gennaro Aquino, G. J. Schwarz +4

Nova Mon 2012 was the first classical nova to be detected as a high energy $\gamma$-ray transient, by Fermi-LAT, before its optical discovery. We study a time sequence of high resolutio…
