Electrical conductivity of warm neutron star crust in magnetic fields: Neutron-drip regime
Arus Harutyunyan, Armen Sedrakian, Narine T. Gevorgyan +1
We compute the anisotropic electrical conductivity tensor of the inner crust of a compact star at non-zero temperature by extending a previous work on the conductivity of the outer…
Bulk viscosity from Urca processes: matter in the neutrino-transparent regime
Mark Alford, Arus Harutyunyan, Armen Sedrakian
We study the bulk viscosity of moderately hot and dense, neutrino-transparent relativistic matter arising from weak-interaction direct Urca processes. This work parallels ou…
The star in RNO 54 -- a post-FUor with short faint jet?
T. Yu. Magakian, T. A. Movsessian, H. R. Andreasyan +2
The aim of the present study was the spectral analysis of an unusual pre-main-sequence star in the cometary nebula RNO 54, which was suspected by several researchers as a FUori-lik…
Herbig-Haro Flows and Young Stars in the Dobashi 5006 Dark Cloud
T. A. Movsessian, T. Yu. Magakian, A. S. Rastorguev +1
Two new Herbig-Haro flows were found in a study of the isolated Dobashi 5006 dark cloud (l, b= 13): one certain (HH 1179) and one presumable, associated…
FUors, EXors and the role of intermediate objects
T. Yu. Magakian, T. A. Movsessian, H. R. Andreasyan
The studies of FUors, EXors and other young eruptive stars are very important for the understanding of the earliest stages of pre-main-sequence evolution. We describe the current s…
Origin of multiwavelength emission from flaring high redshift blazar PKS 0537-286
N. Sahakyan, G. Harutyunyan, D. Israyelyan
The high redhsift blazars powered by supermassive black holes with masses exceeding have the highest jet power and luminosity and are important probes to test the p…
