The AzTEC mm-Wavelength Camera
G. W. Wilson, J. E. Austermann, T. A. Perera +13
AzTEC is a mm-wavelength bolometric camera utilizing 144 silicon nitride micromesh detectors. Herein we describe the AzTEC instrument architecture and its use as an astronomical in…
Interplay between diffusion, accretion and nuclear reactions in the atmospheres of Sirius and Przybylski's star
Alexander Yushchenko, Vera Gopka, Stephane Goriely +8
The abundance anomalies in chemically peculiar B-F stars are usually explained by diffusion of chemical elements in the stable atmospheres of these stars. But it is well known that…
Thorium-rich halo star HD221170: further evidence against the universality of the r-process
Alexander Yushchenko, Vera Gopka, Stephane Goriely +6
We report the abundance determination in the atmosphere of the bright halo star HD221170. The spectra were taken with the Terskol Observatory's 2.0-m telescope with a resolution R=…
Raman Scattered He II 6545 Line in the Symbiotic Star V1016 Cygni
Hee-Won Lee, Young-Jong Sohn, Young Woon Kang +1
We present a spectrum of the symbiotic star V1016 Cyg observed with the 3.6 m Canada-France-Hawaii Telescope, in order to illustrate a method to measure the covering factor of the…
Probing the Spatial Distribution of Extrasolar Planets with Gravitational Microlensing
Cheongho Han, Young Woon Kang
Under the current microlensing planet search strategy of monitoring events caused by stellar-mass lenses, only planets located within a narrow region of separations from central st…
Astrometric Detection of Double Gravitational Microlensing Events
Cheongho Han, Byeong-Gon Park, Wonyong Han +1
If a gravitational microlensing event is caused by a widely separated binary lens and the source approaches both lens components, the source flux is successively magnified by the i…
