Klein-Gordonization: mapping superintegrable quantum mechanics to resonant spacetimes
Oleg Evnin, Hovhannes Demirchian, Armen Nersessian
We describe a procedure naturally associating relativistic Klein-Gordon equations in static curved spacetimes to non-relativistic quantum motion on curved spaces in the presence of…
Mg/Si mineralogical ratio of low-mass planet hosts. Correction for the NLTE effects
V. Adibekyan, H. M. Goncalves da Silva, S. G. Sousa N. C. Santos +2
Mg/Si and Fe/Si ratios are important parameters that control the composition of rocky planets. In this work we applied non-LTE correction to the Mg and Si abundances of stars with…
A search for peculiar stars in the open cluster Hogg 16
Stefano Cariddi, Naira M. Azatyan, Petr Kurfürst +5
The study of chemically peculiar (CP) stars in open clusters provides valuable information about their evolutionary status. Their detection can be performed using the photomet…
Supernovae and their host galaxies - V. The vertical distribution of supernovae in disc galaxies
A. A. Hakobyan, L. V. Barkhudaryan, A. G. Karapetyan +6
We present an analysis of the height distributions of the different types of supernovae (SNe) from the plane of their host galaxies. We use a well-defined sample of 102 nearby SNe…
Note on constants of motion in conformal mechanics associated with near horizon extremal Myers-Perry black holes
Hovhannes Demirchian
We investigate dynamics of probe particles moving in the near-horizon limit of (2N+1)-dimensional extremal Myers-Perry black hole (in the cases of N=3,4,5) with arbitrary rotation…
Investigation of faint galactic carbon stars from the first Byurakan spectral survey. III. Infrared characteristics
K. S. Gigoyan, A. Sarkissian, C. Rossi +5
Infra-Red(IR) astronomical databases, namely, IRAS, 2MASS, WISE, and Spitzer, are used to analyze photometric data of 126 carbon stars whose spectra are visible in the First Byurak…
