Profiles of the Resonance Doublets Formed in Bipolar Winds in Symbiotic Stars
Jerry Jaiyul Yoo, Hee-Won Lee, Sang-Hyeon Ahn
We compute the profiles of resonance doublet lines formed in bipolar winds with velocity greater than the doublet separation in symbiotic stars. Particular attention has been paid…
Lyman alpha line formation in starbursting galaxies II. Extremely Thick, Dustless, and Static HI Media
Sang-Hyeon Ahn, Hee-Won Lee, Hyung Mok Lee
The Lya line transfer in an extremely thick medium of neutral hydrogen is investigated by adopting an accelerating scheme in our Monte Carlo code to skip a large number of core or…
The Kramers-Heisenberg Formula and the Gunn-Peterson Trough from the First Objects in the Universe
Kiehunn Bach, Hee-Won Lee
Recent cosmological observations indicate that the reionized universe may have started at around z=6, where a significant suppression around Ly alpha has been observed from the neu…
Raman Scattered He II Line in the Planetary Nebula M2-9 and the Symbiotic Stars RR Telescopii and He 2-106
Hee-Won Lee, Yong-Woo Kang, Yong-Ik Byun
In this Letter, we report the detection of an emission feature around 6545 Åin the spectra of the bipolar planetary nebula M2-9 and the symbiotic stars RR Telescopii and He 2-106 a…
