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…
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…
The Gaia-ESO Survey: Lithium measurements and new curves of growth
E. Franciosini, S. Randich, P. de Laverny +37
The Gaia-ESO Survey (GES) is a large public spectroscopic survey that was carried out using the multi-object FLAMES spectrograph at the Very Large Telescope. The survey provides ac…
Calibration-based abundances in the interstellar gas of galaxies from slit and IFU spectra
Pilyugin L. S., Lara-Lopez M. A., Vilchez J. M. +3
In this work we make use of available Integral Field Unit (IFU) spectroscopy and slit spectra of several nearby galaxies. The pre-existing empirical R and S calibrations for abunda…
Three-nucleon system: Irreducible and reducible contributions of the three-nucleon force
A. Deltuva, P. U. Sauer
The three-nucleon bound and scattering equations are solved in momentum space for a coupled-channel Hamiltonian. The Hamiltonian couples the purely nucleonic sector of Hilbert spac…
Improving Black Hole Accretion Treatment in Hydrodynamical Simulations
Matas Tartėnas, Kastytis Zubovas
The large galactic scales are connected to the many orders of magnitude smaller supermassive black hole (SMBH) scales by an episodic cycle of feeding and feedback. Active galactic…
