VizieR Online Data Catalog: Abundance analysis of 4 HES metal-poor stars (Shejeelammal+, 2022)

All the four objects analyzed in this study --HE0457-1805, HE0920-0506, HE1241-0337, and HE1327-2116-- are selected from the candidate metal-poor stars identified from the Hamburg/ESO Objective-prism Survey (HES; Christlieb 2003RvMA...16..191C).

The wavelength-calibrated, high-resolution (R~50000) spectrum of HE1241-0337 is taken from the SUBARU/HDS archive (http://jvo.nao.ac.jp/portal/v2/). The wavelength coverage of this spectrum is 4100-6850Å with a wavelength gap between 5440 and 5520Å.

The high-resolution (R~86000) spectra of the objects HE0457-1805, HE0920-0506, and HE1327-2116 were obtained using the High-Efficiency and High-Resolution Mercator Echelle Spectrograph (HERMES) attached to the 1.2m Mercator telescope at the Roque de los Muchachos Observatory in La Palma, Canary Islands, Spain, operated by the Institute of Astronomy of the KU Leuven, Belgium. The HERMES spectra cover the wavelength range 3770-9000Å. Multiple frames of each object were taken on different nights: 15 frames with exposures of 1800 and 2100s for HE 0457-1805 during the period 2013-2016, 10 frames with exposures ranging from 750 to 1800s for HE0910-0506 during 2018-2020, and three frames with exposures of 1200s for HE 1327-2116 on 2019 January 31 and 2019 February 1.
