Rotational Disruption of Dust Grains by Radiative Torques in Strong Radiation Fields

Thiem Hoang, Le Ngoc Tram, Hyeseung Lee +1

Massive stars, supernovae, and kilonovae are among the most luminous radiation sources in the universe. Observations usually show near- to mid-infrared (NIR--MIR, $λ \sim 1 - 5 μ$ m) e…

Broad Wings around H $α$ and H $β$ in the Two S-Type Symbiotic Stars Z Andromedae and AG Draconis

Seok-Jun Chang, Hee-Won Lee, Ho-Gyu Lee +3

Symbiotic stars often exhibit broad wings around Balmer emission lines, whose origin is still controversial. We present the high resolution spectra of the S type symbiotic stars Z…

Escape of Resonantly Scattered Ly $β$ and H $α$ from Hot and Optically Thick Media

Seok-Jun Chang, Hee-Won Lee, Sang-Hyeon Ahn +4

We investigate the escape of Ly $β$ from emission nebulae with a significant population of excited hydrogen atoms in the level $n = 2$ , rendering them optically thick in H $α$ . The tra…
