Spectroscopic study of Ba and CEMP-s stars: Mass distribution of AGB progenitors
Partha Pratim Goswami, Aruna Goswami
We have performed detailed high-resolution spectroscopic analysis on seven metal-poor stars (BD+75 348, BD+09 3019, HD238020, HE0319-0215, HE0507-1653, HE0930-0018, HE1023-1504) an…
The peculiar abundances of HE 1005-1439. A carbon-enhanced extremely metal-poor star contaminated with products of both s-and i-process nucleosynthesis
Partha Pratim Goswami, Aruna Goswami
We performed a detailed, high-resolution spectroscopic analysis of HE 1005-1439 based on SUBARU/HDS spectra with an R ~ 50000. Abundances of ten light elements from C through Ni an…
Spectroscopic study of CEMP-(s & r/s) stars- Revisiting classification criteria and formation scenarios, highlighting i-process nucleosynthesis
Partha Pratim Goswami, Rajeev Singh Rathour, Aruna Goswami
We have derived the stellar atmospheric parameters, the effective temperature T, the microturbulent velocity , the surface gravity log g, and the metallicity [Fe/H] for…
i-process nucleosynthesis: observational evidences from CEMP stars
Partha Pratim Goswami, Aruna Goswami
The surface chemical compositions of a large fraction of Carbon-Enhanced Metal-Poor (CEMP) stars, the so-called CEMP-r/s stars, are known to exhibit enhancement of both s- and r-pr…
Characterizing the companion AGBs using surface chemical composition of barium stars
J. Shejeelammal, Aruna Goswami, Partha Pratim Goswami +2
Barium stars are one of the important probes to understand the origin and evolution of slow neutron-capture process elements in the Galaxy. These are extrinsic stars, where the obs…
Chemical analysis of CH stars - III: Atmospheric parameters and elemental abundances
Meenakshi Purandardas, Aruna Goswami, Partha Pratim Goswami +2
Elemental abundances of CH stars can provide observational constraints for theoretical studies on the nucleosynthesis and evolution of low- and intermediate-mass stars. However, av…
