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…
Initial Results from the USNO Dispersed Fourier Transform Spectrograph
Arsen R. Hajian, Bradford B. Behr, Andrew T. Cenko +15
We have designed and constructed a ``dispersed Fourier Transform Spectrometer'' (dFTS), consisting of a conventional FTS followed by a grating spectrometer. By combining these two…
Elemental Abundance Ratios in Stars of the Outer Galactic Disk. III. Cepheids
David Yong, Bruce W. Carney, Luisa de Almeida +1
We present metallicities, [Fe/H], and elemental abundance ratios, [X/Fe], for a sample of 24 Cepheids in the outer Galactic disk. The sample have Galactocentric distances covering…
Solar cycle variation in solar f-mode frequencies and radius
H. M. Antia, Sarbani Basu, J. Pintar +1
Using data from the Global Oscillation Network Group (GONG) covering the period from 1995 to 1998, we study the change with solar activity in solar f-mode frequencies. The results…
