MOLYBDENUM AND RUTHENIUM ABUNDANCES IN COOL STARS OF THE GALACTIC DISC
Journal Title: Odessa Astronomical Publications - Year 2017, Vol 30, Issue
Abstract
We revise the molybdenum and ruthenium abundances in FGK stars with metallicities ranging from −1.0 < [Fe/H] < +0.3. The observed stars belong to the substructures of the Galaxy. The observations were conducted using the 1.93 m telescope at Observatoire de Haute-Provence (OHP, France) equipped with the echelle type spectrographs ELODIE and SOPHIE. The results are based on analyses of spectra that have a typical S/N ~ 100-300 and a resolution of 42 000. These estimates were obtained using synthetic spectra computed with LTE model atmosphere.

3D NUMERICAL HYDRODYNAMICAL SIMULATIONS OF A RADIATION-DRIVEN JET LAUNCH AND DISAPPEARING OVER LOW/HARD STATE
In the present research we have calculated 3D numerical hydrodynamical simulations of a radiation-driven jet launch and disappearing over low/hard state. The calculations show that the jet launch occurs at the beginning...
