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…

I. A. Zinchenko, L. S. Pilyugin
We constructed an oxygen abundance map and N/O ratio map of the unusually low excitation dwarf irregular galaxy NGC 4163 based on publicly available spectroscopy obtained by the Ma…
The Gaia-ESO Survey: Old super-metal-rich visitors from the inner Galaxy
M. L. L. Dantas, R. Smiljanic, R. Boesso +12
We report the identification of a set of old super metal-rich dwarf stars with orbits of low eccentricity that reach a maximum height from the Galactic plane between ~0.5-1.5 kpc.…
Distribution of shifted discrete random walk generated by distinct random variables and applications in ruin theory

In this paper, we set up the distribution function and the generating function of ,…
Non-Hermitian Mode Cleaning in Periodically Modulated Multimode Fibers
M. N. Akhter, S. B. Ivars, M. Botey +2
We show that the simultaneous modulation of the propagation constant and of the gain/loss coefficient along the multimode fibers results in unidirectional coupling among the modes,…
Signatures of the isobar in spin observables of electrodisintegration
A. Deltuva
The electrodisintegration of is considered focusing on the effects of the isobar excitation which is treated dynamically on the same footing as nucleons. In t…
MINCE I. Presentation of the project and of the first year sample
G. Cescutti, P. Bonifacio, E. Caffau +20
In recent years, Galactic archaeology has become a particularly vibrant field of astronomy, with its main focus set on the oldest stars of our Galaxy. In most cases, these stars ha…
Extremely Narrow, Sharp-Peaked Resonances at the Edge of the Continuum
Ignas Lukosiunas, Lina Grineviciute, Julianija Nikitina +2
We report a critical narrowing of resonances of a driven potential well, when their eigenfrequencies approach the edge of the continuum. The resonances also obtain unusual sharp-pe…
