Spectroscopic age estimates for APOGEE red-giant stars: Precise spatial and kinematic trends with age in the Galactic disc
F. Anders, P. Gispert, B. Ratcliffe +12
Over the last few years, many studies have found an empirical relationship between the abundance of a star and its age. Here we estimate spectroscopic stellar ages for 178 825 red-…
The Gaia-ESO Survey: Probing the lithium abundances in old metal-rich dwarf stars in the Solar vicinity
M. L. L. Dantas, G. Guiglion, R. Smiljanic +14
We test a scenario in which radial migration could affect the Li abundance pattern of dwarf stars in the solar neighbourhood. This may confirm that the Li abundance in these stars…
Ab-initio study of stable 3d, 4d and 5d transition metal based Quaternary Heusler compounds
Sashi Nepal, Ramesh Dhakal, Iosif Galanakis +3
The realization of the stable structure of Heusler compounds and the study of different properties is an important step for their potential application in spintronics and magnetoel…
The Gaia-ESO Survey: Chemical evolution of Mg and Al in the Milky Way with Machine-Learning
M. Ambrosch, G. Guiglion, Š. Mikolaitis +14
We aim to prepare the machine-learning ground for the next generation of spectroscopic surveys, such as 4MOST and WEAVE. Our goal is to show that convolutional neural networks can…
Prediction of half-metallicity and spin-gapless semiconducting behavior in the new series of FeCr-based quaternary Heusler alloys: an ab initio study
Ramesh Dhakal, Sashi Nepal, Iosif Galanakis +2
This paper presents a detailed investigation of FeCr-based quaternary Heusler alloys. By using ultrasoft pseudopotential, electronic and magnetic properties of the compounds are st…
Effect of doping on SGS and weak half-metallic properties of inverse Heusler Alloys
R. Dhakal, S. Nepal, R. B. Ray +2
Heusler alloys with Mn and Co have been found to exhibit interesting electronic and magnetic properties. MnCoAl is well known SGS compound while MnCoGa has weak half metall…
Ab initio study of the half-metallic full-Heusler compounds CoZAl [Z = Sc, Ti, V, Cr, Mn, Fe]; the role of electronic correlations
Sashi Nepal, Ramesh Dhakal, Iosif Galanakis
We study the structural, electronic, and magnetic properties of CoZAl compounds employing a pseudopotential electronic bandstructure method. The stability of the compounds is e…
