Resolved star formation in the metal-poor star-forming region Magellanic Bridge C
(Oxford University Press, 2020)
Magellanic Bridge C (MB-C) is a metal-poor (similar to 1/5 Z(circle dot)) low-density star-forming region located 59 kpc away in the Magellanic Bridge, offering a resolved view of the star formation process in conditions ...
A SEARCH FOR UNRECOGNIZED CARBON-ENHANCED METAL-POOR STARS IN THE GALAXY
(IOP PUBLISHING LTD, 2010)
We have developed a new procedure to search for carbon-enhanced metal-poor (CEMP) stars from the Hamburg/ESO (HES) prism-survey plates. This method employs an extended line index for the CH G band, which we demonstrate to ...
An overview of the rotational bechavior of metal-poor stars
(Sociedade Astronômica Americana, 2020)
Metal-poor stars observed with the Magellan Telescope. II. Discovery of four stars with [Fe/H] <= −3.5
(American Astronomical SocietyChicago, 2014)
We report on the discovery of seven low-metallicity stars selected from the Hamburg/ESO Survey, six of which are
extremely metal-poor (EMP, [Fe/H] −3.0), with four having [Fe/H] −3.5. Chemical abundances or upper
limits ...
Lithium abundance in lower red giant branch stars of Omega Centauri
(EDP Sciences, 2018-10)
We present Li, Na, Al, and Fe abundances of 199 lower red giant branch star members of the stellar system Omega Centauri, using high-resolution spectra acquired with FLAMES at the Very Large Telescope. The A(Li) distribution ...
An Overview of the Rotational Behavior of Metal-poor Stars
(2009)
We describe the behavior of the rotational velocity in metal-poor stars ([Fe/H] ~ -0.5 dex) at different evolutionary stages, based on v sin i values from the literature. Our sample is composed of stars in the field and ...

Elemental abundances and classification of carbon-enhanced metal-poor stars
(EDP SCIENCES S ALES ULIS CEDEX A, 2012)
We present a detailed study of carbon-enhanced metal-poor (CEMP) stars, based on high-resolution spectroscopic observations of a sample of 18 stars. The stellar spectra for this sample were obtained at the 4.2 m William ...
[O/Fe] ESTIMATES FOR CARBON-ENHANCED METAL-POOR STARS FROM NEAR-INFRARED SPECTROSCOPY
(IOP PUBLISHING LTD, 2011)
We report on oxygen abundances determined from medium-resolution near-infrared spectroscopy for a sample of 57 carbon-enhanced metal-poor (CEMP) stars selected from the Hamburg/ESO Survey. The majority of our program stars ...
