Abstract:
This paper presents the detailed abundances and r-process
classifications of 125 newly identified metal-poor stars as part of an
ongoing collaboration, the R-Process Alliance. The stars were
identified as metal-poor candidates from the RAdial Velocity
Experiment (RAVE) and were followed up at high spectral resolution
(R∼31500) with the 3.5m telescope at Apache Point Observatory. The
atmospheric parameters were determined spectroscopically from FeI
lines, taking into account <3D> non-LTE corrections and using
differential abundances with respect to a set of standards. Of the 125
new stars, 124 have [Fe/H]<-1.5, 105 have [Fe/H]<-2.0, and 4 have
[Fe/H]<-3.0. Nine new carbon-enhanced metal-poor stars have been
discovered, three of which are enhanced in r-process elements.
Abundances of neutron-capture elements reveal 60 new r-I stars (with
+0.3≤[Eu/Fe]≤+1.0 and [Ba/Eu]<0) and 4 new r-II stars (with
[Eu/Fe]>+1.0). Nineteen stars are found to exhibit a "limited-r"
signature ([Sr/Ba]>+0.5, [Ba/Eu]<0). For the r-II stars, the second-
and third-peak main r-process patterns are consistent with the
r-process signature in other metal-poor stars and the Sun. The
abundances of the light, α, and Fe-peak elements match those of
typical Milky Way (MW) halo stars, except for one r-I star that has
high Na and low Mg, characteristic of globular cluster stars.
Parallaxes and proper motions from the second Gaia data release yield
UVW space velocities for these stars that are consistent with
membership in the MW halo. Intriguingly, all r-II and the majority of
r-I stars have retrograde orbits, which may indicate an accretion
origin.
Description:
All targets were observed in 2015-2017 with the Astrophysical Research
Consortium (ARC) 3.5m telescope at Apache Point Observatory (APO). The
seeing ranged from 0.6" to 2", with a median value of 1.15". The ARC
Echelle Spectrograph (ARCES) was utilized in its default setting, with
a spectral resolution of R∼31500, covering the entire optical range,
from 3800 to 10400Å.
