Towards a better understanding of the distance scale from RR Lyrae variable stars: A case study for the inner halo globular cluster NGC 6723
Jae-Woo Lee, Mercedes Lopez-Morales, Kyeong-Soo Hong +3
We present BV photometry for 54 variables in the metal-rich inner halo globular cluster NGC6723. With the discovery of new RR Lyrae variables (RRLs), we obtain <P_ab> = 0.541 +/- 0…
Enrichment by supernovae in globular clusters with multiple populations
Jae-Woo Lee, Young-Woon Kang, Jina Lee +1
The most massive globular cluster in the Milky Way, omega Centauri, is thought to be the remaining core of a disrupted dwarf galaxy, as expected within the model of hierarchical me…
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…
