High Resolution {\it BOES} Spectroscopy of Raman-scattered He~II6545 in Young Planetary Nebulae
Jin Lim, Seok-Jun Chang, Jaejin Shin +5
Young planetary nebulae (PNe) are characterized by their hot central stars and the presence of abundant neutral and molecular components, which result from significant mass loss du…
Discovery of Raman-scattered He II 6545 in the Planetary Nebulae NGC 6886 and NGC 6881
Bo-Eun Choi, Hee-Won Lee
Young planetary nebulae (PNe) retain a large amount of neutral material that was shed in the previous asymptotic giant branch stage. The thick H I region in young PNe can be effect…
Line Formation of Raman-Scattered He II 4851 in an Expanding Spherical H I Shell in Young Planetary Nebulae
Bo-Eun Choi, Seok-Jun Chang, Ho-Gyu Lee +1
We investigate line formation of Raman-scattered He II at 4851 in an expanding neutral spherical shell that surrounds a point-like He II source located at the center. A new grid-ba…
RAMSES II - RAMan Search for Extragalactic Symbiotic Stars. Project concept, commissioning, and early results from the science verification phase
R. Angeloni, D. R. Gonçalves, S. Akras +16
Symbiotic stars (SySts) are long-period interacting binaries composed of a hot compact star, an evolved giant star, and a tangled network of gas and dust nebulae. They represent un…
