Equivalent widths of 26 metal-poor stars
Listed in IVOA Registry (Virtual Observatory)
The chemical compositions of 26 metal-poor stars that exhibit strong CH and/or C2 molecular bands are determined.
Description
Twenty-two stars in our sample satisfy our definition for carbon-enhanced metal-poor (CEMP) stars based on the carbon abundance ratio ([C/Fe]) and the evolutionary status. In addition, we measure Na abundances for nine known carbon-enhanced stars.
Combining our new sample with the results of previous work, we investigate the abundance and evolutionary status of a total of 64 CEMP stars.
