Observational constraints on first-star Nucleosynthesis: II. spectroscopy of an ultra metal-poor CEMP-no star
We report on the first high-resolution spectroscopic analysis of HE 0020-1741, a bright ( V = 12.9), ultra metal-poor ( ##IMG## [http://ej.iop.org/images/0004-637X/833/1/21/apjaa431dieqn1.gif] $[\mathrmFe/\rmH]$ = −4.1), carbon-enhanced ( ##IMG## [http://ej.iop.org/images/0004-637X/833/1/21/apjaa431...
