Stellar substructures in the Galactic disc and halo: Properties, origins, and evolution

Deepak

Spatial, kinematic, and orbital properties, along with ages and chemical compositions of the thin disc, thick disc, and various stellar substructures in the halo, are studied based…

On the Metallicity Gradients in the Galactic Disk using Open Clusters

Yogesh C. Joshi, Deepak, Sagar Malhotra

We study the metallicity distribution and evolution in the Galactic disk based on the largest sample of open star clusters in the Galaxy. From the catalogue of 1879 open clusters i…

Lithium in red giants: the roles of the He-core flash and the luminosity bump

Deepak, David L. Lambert

Lithium abundances for red giants in the GALAH DR3 survey are studied. The rare examples of Li-enriched stars with abundances A(Li) are confirmed to be He-core burning s…

Lithium abundances and asteroseismology of red giants: understanding the evolution of lithium in giants based on asteroseismic parameters

Deepak, David L. Lambert

In this study, we explore the evolution of lithium in giant stars based on data assembled from the literature on asteroseismology and Li abundances for giants. Our final sample of…

Abundance analyses of Li-enriched and normal giants in the GALAH survey

Deepak, David L. Lambert, Bacham Eswar Reddy

Compositions of lithium-enriched and normal giants among the GALAH survey are compared. Except for Li, the only detectable abundance difference between lithium-enriched and normal…

Study of Lithium Rich Giants with the GALAH Spectroscopic Survey

Deepak, Bacham Eswar Reddy

In this article, we speculate on the possible mechanisms for Li enhancement origin in RGB stars based on a large data set of around 340,299 stars collected from the GALAH survey co…
