Abundance analysis of s-process enhanced barium stars

Mahanta, Upakul; Drisya, K; Goswami, A; Duorah, K (Oxford University Press on behalf of the Royal Astronomical Society, 2016-12-01)

Detailed chemical composition studies of stars with enhanced abundances of neutron-capture elements can provide observational constraints for neutron-capture nucleosynthesis studies and clues for understanding their ...
Contribution of Proton Capture Reactions to the Ascertained Abundance of Fluorine in the Evolved Stars of Globular Cluster M4, M22, 47 Tuc and NGC 6397

Mahanta, Upakul; Goswami, A; Duorah, H. L; Duorah, K (Indian Academy of Sciences, 2017-12)

The origin of the abundance pattern and also the (anti)correlation present among the elements found in stars of globular clusters (GCs) remains unimproved until date. The proton-capture reactions are presently recognised ...
p-capture reaction cycles in rotating massive stars and their impact on elemental abundances in globular cluster stars: A case study of O, Na and Al

Mahanta, Upakul; Goswami, A; Duorah, H. L; Duorah, K (IOP Publishing, 2017-08)

Elemental abundance patterns of globular cluster stars can provide important clues for understanding cluster formation and early chemical evolution. The origin of the abundance patterns, however, still remains poorly ...
