Abundances in the Local Region I: G and K Giants
R. Earle Luck
Parameters and abundances for 1133 stars of spectral types F, G, and K of luminosity class III have been derived. In terms of stellar parameters, the primary point of interest is t…
Oxygen abundance distribution in Galactic disc
S. A. Korotin, S. M. Andrievsky, R. E. Luck +3
We have performed a NLTE analysis of the infrared oxygen triplet for a large number of cepheid spectra obtained with the Hobby-Eberly telescope. These data were combined with our p…
The Pulsation Mode and Distance of the Cepheid FF Aquilae
D. G. Turner, V. V. Kovtyukh, R. E. Luck +1
The determination of pulsation mode and distance for field Cepheids is a complicated problem best resolved by a luminosity estimate. For illustration a technique based on spectrosc…
Barium Abundances in Cepheids
S. M. Andrievsky, J. R. D. Lepine, S. A. Korotin +3
We derived the barium atmospheric abundances for a large sample of Cepheids, comprising 270 stars. The sample covers a large range of galactocentric distances, from about 4 to 15 k…
The Distribution of the Elements in the Galactic Disk III. A Reconsideration of Cepheids from l = 30 to 250 Degrees
R. Earle Luck, David L. Lambert
This paper reports on the spectroscopic investigation of 238 Cepheids in the northern sky. Of these stars, about 150 are new to the study of the galactic abundance gradient. These…
The Distribution of the Elements in the Galactic Disk II. Azimuthal and Radial Variation in Abundances from Cepheids
R. E. Luck, S. M. Andrievsky, V. V. Kovtyukh +2
This paper reports on the spectroscopic investigation of 101 Cepheids in the Carina region. These Cepheids extend previous samples by about 35% in number and increase the amount of…
