Detection of Diatomic Molecules in the Dust Forming Nova V2676 Oph
Autor: Nagashima, M.; Arai, A.; Kajikawa, T.; Kawakita, H.; Kitao, E.; Arasaki, T.; Taguchi, G.; Ikeda, Y.
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)Novae are generally considered to be hot astronomical objects and show effective temperatures up to 10,000 K or higher at their visual maximum. But, it is theoretically predicted that the outer envelope of the nova outflow ... -
