ABSTRACT
We have obtained high-resolution (R ’ 50;000 or 90,000), high-quality (S=N k100) spectra of 22 very metal-
poor stars ([Fe/H?P ? 2:5) with the High Dispersion Spectrograph fabricated for the 8.2 m Subaru Telescope.
The spectra cover the wavelength range from 3500 to 5100 8; equivalent widths are measured for isolated lines
of numerous elemental species, including the ?-elements, the iron-peak elements, and the light and heavy
neutron-capture elements. Errors in the measurements and comparisons with previous studies are discussed.
These data will be used to perform detailed abundance analyses in the following papers of this series. Radial
velocities are also reported and are compared with previous studies. At least one moderately r-process–enhanced
metal-poor star, HD 186478, exhibits evidence of a small-amplitude radial velocity variation, confirming the
binary status noted previously. During the course of this initial program, we have discovered a new moderately
r-process–enhanced, very metal-poor star, CS 30306?132 ([Fe/H? ¼ ?2:4; [Eu/Fe? ¼ þ0:85), which is discussed
in detail in the companion paper.

1. INTRODUCTION
Very metal-poor stars ([Fe/H? P ? 2:5)13are believed to
have been born in the early Galaxy; their chemical composi-
tions are living records of the nucleosynthesis processes that
preceded their formation. As a result of considerable efforts
by many astronomers, a large list of candidate stars with
[Fe/H? < ?2:5 have been provided by wide-field objective-
prism surveys in the past two decades (e.g., the HK survey:
Beers, Preston, & Shectman 1985, 1992, Beers 1999; and the
Hamburg/ESO Survey: Christlieb & Beers 2000, Christlieb
et al. 2001, Christlieb 2003). Over the past several years, high-
resolution spectroscopic studies have enabled the measure-
ment of elemental abundances for many of the metal-poor
stars found by these surveys (e.g., McWilliam et al. 1995a;
Ryan, Norris, & Beers 1996; Burris et al. 2000; Carretta et al.
2002; Cayrel et al. 2004), including detailed studies of the
lowest metallicity stars yet identified (e.g., Norris, Ryan, &
Beers 2001; Christlieb et al. 2002). These observational
studies, which continue at present, are providing strong con-
straints on models of the dominant nucleosynthesis processes
in the earliest epochs of star formation in our Galaxy, in
particular those associated with massive stars and Type II
supernovae.
Remarkable progress has been made, in particular, through
studies of the neutron-capture elements in very metal-poor
stars. High-resolution spectroscopic studies of very metal-
poor stars have revealed, for example, that a small fraction
(presently estimated to be on the order of 2%–3%, T. C. Beers
2003, private communication) of giants with ½Fe=H? < ?2:5
exhibit large overabundances (e.g., ½r-process=Fe? > þ1:0) of
neutron-capture elements associated with the r-process (e.g.,
[r-process/Fe? > þ1:0 ; McWilliam et al. 1995a; Sneden et al.
2000, 2003; Cayrel et al. 2001; Hill et al. 2002). These, along
with a handful of other metal-poor stars with moderately en-
hanced r-process elements (þ0:5 ? ½r-process/Fe? ? þ1:0,
e.g., Westin et al. 2000; Johnson & Bolte 2001; Cowan et al.
2002), display remarkably similar abundance patterns in the
range 56 ? Z < 76, all apparently in good agreement with
the solar-system r-process component. In addition, some of

the neutron-capture–enhanced, metal-poor stars exhibit abun-
dance patterns associated with s-process nucleosynthesis (e.g.,
Norris, Ryan, & Beers 1997; Van Eck et al. 2001; Aoki et al.
2002; Lucatello et al. 2003).
These efforts are having a large collective impact on studies
on the origin of the neutron-capture elements in the Galaxy
(e.g., Ishimaru & Wanajo 1999; Fields, Truran, & Cowan
2002; Qian & Wasserburg 2002), and on the underlying
physics and astrophysical sites of the r- and s-processes (e.g.,
Gallino et al. 1998; Wanajo et al. 2002, 2003; Schatz et al.
2002; Truran et al. 2002). Furthermore, detailed studies of the
r-process–enhanced, very metal-poor stars have provided
new, potentially quite powerful, methods for obtaining hard
lower limits on the age of the Galaxy and the universe, from
the application of cosmo-chronometry based on the observed
(present-day) abundance ratios of radioactive nuclei (Th and
U), as compared with one another, and with stable elements
originating in the r-process, (e.g., Eu, Sneden et al. 1996;
Westin et al. 2000; Cayrel et al. 2001; Schatz et al. 2002;
Wanajo et al. 2002, 2003; Sneden et al. 2003).
In order to develop a more clear understanding of the in-
dividual nucleosynthetic processes that were operating in the
early Galaxy, further abundance studies are required, based on
high-quality spectra, for much larger samples of very metal-
poor stars than have been examined to date. We have initiated
such a set of investigations with the Subaru Telescope High
Dispersion Spectrograph (HDS, Noguchi et al. 2002). In this
paper we present observations of 22 very metal-poor stars
observed during the commissioning phase of this instrument.
In x 2 we discuss the selection of targets and details of the
observations that have been carried out. Our spectra cover the
wavelength range from 3500 to 5100 8 with high spectral
resolution (a resolving power of R ¼ 50;000 or 90,000) and
high signal-to-noise (S=N k100 per resolution element). We
report the equivalent widths measured for the spectra in x 3,
where we also discuss the random errors of our measurements
and make comparisons with previous studies of stars in
common. Radial velocity measurements for our program stars
are presented in x 4, along with a comparison with previous
measurements for a number of stars. These data will be used in
the detailed abundance analyses that will follow in additional
papers of this series.
2. OBSERVATIONS
2.1. Selection of Targets
The present work is focused primarily on the observed
abundance patterns of r-process elements in very metal-poor
stars. Accordingly, our sample was selected to include stars
that fall into one of several categories: (1) very metal-poor
stars that were previously known to exhibit extremely large
enhancements of their r-process elements (CS 22892?052 and
CS 31082?001: Sneden et al. 1996; Cayrel et al. 2001);
(2) bright metal-poor stars that were studied by previous
authors (e.g., McWilliam et al. 1995a; Burris et al. 2000) and
shown to be moderately r-process-element–rich; and (3) can-
didate very metal-poor giants discovered in the course of
the HK survey of Beers and colleagues (Beers et al. 1992;
Fig. 1.—Examples of spectra for nine stars in our sample over the wave-
length range 4000–4040 8. The star names and [Fe/H] values reported in
Paper II are presented in the figure. This spectral region includes the line of
Th ii at 4019 8; detections are indicated with a vertical arrow. The apparent
emission lines seen in some of the spectra result from imperfect cosmic-ray
cleaning.

temperatures of these stars are quite similar to one another) and the Eu ii
