THE PHYSICAL PARAMETERS OF THE GAS AND DUST IN COMETARY ATMOSPHERES
Journal Title: Odessa Astronomical Publications - Year 2015, Vol 28, Issue 2
Abstract
The results of observations and studies of comets on the basis of the optical spectra with an average resolution were presented. Spectral material was mainly produced in 2009–2012 with the help 2-m telescope Zeiss (F1 = 6.3 m, F2 = 16 m) at high mountain astronomical station "Terskol" of Main Astronomical Observatory of National Academy of Sciences of Ukraine and the Institute of Astronomy RAS. The resolution of the spectra R ≈ 1500, R ≈ 4500, R ≈ 14000, wavelength ranges λλ = 3850–8000 ÅÅ. Using the spectra of comets, based on the model Hazer, was performed the following work: carried out the identification of spectral emission lines, obtained physical parameters of the neutral gas atmosphere of comets. And also, physical parameters the dusty atmosphere.

TRACKING TYPE III RADIO BURST SOURCES IN THE SOLAR CORONA BY HELIOGRAPHIC MEANS
We present the preliminary results of heliographic measurements of solar type III radio bursts in the lowfrequency range (16.5-33 MHz) using the UTR-2 radio heliograph. The radio astronomy tools permit us t...
THE EXISTENCE OF GROUPS OF METEORITE-PRODUCING FIRE-BALLS AND METEORITES IN COMET-LIKE ORBITS
This paper discusses the existence of groups of meteorite-producing fireballs and ordinary chondrites in the Earth-crossing Jupiter-family comet-like (JFC) orbits. The similarity of the orbits of meteorite-producing fire...
RE-CLASSIFICATION OF THE NEGLECTED VARIABLE V480 AQL
We present the results of multicoloured photometric study of previously neglected variable star V480 Aql. Our V RI observations prove that this star belongs to classical Cepheids with the period of P = 19d.0016. We also...
