Classification and characterization using HCT/HFOSC spectra of carbon stars selected from the HES survey

Meenakshi Purandardas, Aruna Goswami

We present results from the analysis of 88 carbon stars selected from Hamburg/ESO (HES) survey using low-resolution spectra (R1330 \& 2190). The spectra were obtained with th…

Peculiar abundances of the cool carbon star HE 1104-0957

Meenakshi Purandardas, Aruna Goswami, Sridharan Rengasamy

We present, for the first time, a detailed abundance analysis of the carbon star HE 11040957 based on high resolution (R 50\,000) spectra. Our analysis shows that the ob…

On the potential of Carbon-Enhanced Metal-Poor stars for Galactic Archaeology

Aruna Goswami, J Shejeelammal, Partha Pratim Goswami +1

The low-mass metal-poor stars in the Galaxy that preserve in their atmosphere, the chemical imprints of the gas clouds from which they were formed can be used as probes to get insi…

LAMOST J045019.27+394758.7, with peculiar abundances of N, Na, V, Zn, is possibly a Sculptor dwarf galaxy escapee

Meenakshi Purandardas, Aruna Goswami, J. Shejeelammal +5

We present the results of the high-resolution (R60,000) spectroscopic analysis of the star LAMOSTJ045019.27+394758.7 (hereafter J045) from the list of carbon stars of LAMOST…

Observational evidence points at AGB stars as possible progenitors of CEMP-s & r/s stars

Meenakshi Purandardas, Aruna Goswami

Origin of enhanced abundance of heavy elements observed in the surface chemical composition of carbon-enhanced metal-poor (CEMP) stars still remain poorly understood. Here, we pres…

Chemical analysis of two extremely metal-poor stars HE 2148-2039 and HE 2155-2043

Meenakshi Purandardas, Aruna Goswami

We present elemental abundance results for HE 2148-2039 and HE 2155-2043 based on a detailed high-resolution spectroscopic analysis. The high-resolution SUBARU/HDS spectra used for…
