Active galactic nucleus activity in nearby disk galaxies: The roles of bar strength and spiral arm morphology
Zh. R. Martirosyan, A. A. Hakobyan, V. Adibekyan +3
(abridged) We investigate the dependence of AGN activity on bar strength and spiral arm morphology in nearby spiral galaxies, with a particular emphasis on disentangling their indi…
Supernovae Ia ejecta velocities and host galaxy environments: the role of survey-selection effects
L. V. Barkhudaryan, A. A. Hakobyan, M. H. Gevorgyan +6
The origin of the near-maximum-light Si II 6355 velocity diversity among supernovae Ia (SNe Ia) remains uncertain. Previous studies have suggested that high-velocity (HV) and no…
Inferring stellar metallicity and elemental abundances from kinematic and spectroscopic data using machine learning -- Implications for exoplanet host stars
V. Adibekyan, B. M. T. B. Soares, S. G. Sousa +7
(abridged) Elemental abundances of FGK stars can be derived routinely from high-resolution optical spectra, but this remains considerably more difficult for cooler stars. Machine-l…
Linking the primordial composition of planet building disks to the present-day composition of rocky exoplanets
V. Adibekyan, M. Deal, C. Dorn +16
The composition of rocky planets is strongly driven by the primordial materials in the protoplanetary disk, which can be inferred from the abundances of the host star. Understandin…
Density discrepancy between transit-timing variations and radial velocity: Insights from the host star composition
V. Adibekyan, S. G. Sousa, S. C. C. Barros +5
The determination of planetary densities from the masses derived with the radial velocity (RV) and transit-timing variation (TTV) methods reveals discrepancies. Specifically, plane…
