Asymmetry of Lines in the Spectra of the Sun and Solar-Type Stars
V. A. Sheminova
We have analysed the asymmetry of lines Fe I and Fe II in spectra of a solar flux using three FTS atlases and the HARPS atlas and also in spectra of 13 stars using observation data…
Imaging polarimetry and photometry of comet 21P/Giacobini-Zinner
E. Chornaya E. Zubko, I. Luk'yanyk, A. Kochergin +8
We report results of polarimetric observations of comet 21P/Giacobini-Zinner made at phase angles, α=76-78 deg, between 10 and 17 of September 2018, and compare them with previous…
A comparison of methods for finding magnetic nulls in simulations and in situ observations of space plasmas
Vyacheslav Olshevsky, David Pontin, Benjamin Williams +5
Magnetic nulls are ubiquitous in space plasmas, and are of interest as sites of localized energy dissipation or magnetic reconnection. As such, a number of methods have been propos…
Two types of distribution of the gas velocity dispersion of MaNGA galaxies
L. S. Pilyugin, I. A. Zinchenko, M. A. Lara-Lopez +2
The distribution of the gas velocity dispersion sigma across the images of 1146 MaNGA galaxies is analyzed. We find that there are two types of distribution of the gas velocity dis…
Monitoring polarization in comet 46P/Wirtanen
M. Zheltobryukhov, E. Zubko, E. Chornaya +9
We measure the degree of linear polarization of comet 46P/Wirtanen during two months, embracing the perihelion passage in 2018 December with phase angles ranging from α=18.1 to 46.…
A Photometric and Dynamic Study of Comet C/2013 A1 (Siding Spring) from Observations at a Heliocentric Distance of ~4.1 AU
Yu. S. Andrienko, A. V. Golovin, A. V. Ivanova +3
An analysis is presented for the photometric data on comet C/2013 A1 (Siding Spring) from observations at a large heliocentric distance (near 4.1 AU). Comet C/2013 A1 (Siding Sprin…
