Spatial orientation and shape of the velocity ellipsoids of the Gaia DR3 giants and subgiants in the Galactic plane
A. M. Dmytrenko, P. N. Fedorov, V. S. Akhmetov +8
We present the results of determining the parameters characterizing the shape and orientation of residual velocity ellipsoids from the Gaia DR3 red giants and subgiants. We show th…
Chemical enrichment in LINERs from MaNGA. I. Tracing Oxygen and Nitrogen Nuclear Abundances in LINERs with Varied Ionizing Sources
Borja Pérez-Díaz, Enrique Pérez-Montero, Igor A. Zinchenko +1
The chemical enrichment in low-ionization nuclear emission-line regions (LINERs) is still an issue with spatial resolution spectroscopic data due to the lack of studies and the unc…
NGC3521 as the Milky Way analogue: spectral energy distributon from UV to Radio and photometric variability
O. S. Pastoven, O. V. Kompaniiets, I. B. Vavilova +1
We studied the multiwavelength properties of NGC 3521, the Milky Way galaxy-twin, from UV- to radio, exploring the data from GALEX for UV-, SDSS for optical, 2MASS, WISE, MIPS (Spi…
Non-Local Thermodynamic Equilibrium inversions of the Si I 10827 A spectral line
C. Quintero Noda, N. G. Shchukina, A. Asensio Ramos +4
Inferring the coupling of different atmospheric layers requires observing spectral lines sensitive to the atmospheric parameters, particularly the magnetic field vector, at various…
Cosmological insights into the early accretion of r-process-enhanced stars II. Dynamical identification of lost members of Reticulum II
P. Berczik, M. Ishchenko, O. Sobodar +1
Aims. We identify the possible dynamical connection between individual r-process-enhanced stars and the ultra-faint dwarf galaxy Reticulum II based on the current phase-space infor…
Evolution of the disky second generation of stars in globular clusters on cosmological timescale
Peter Berczik, Taras Panamarev, Maryna Ishchenko +1
Context. Many Milky Way globular clusters (GCs) host multiple stellar populations, challenging the traditional view of GCs as single-population systems. It has been suggested that…
