    Astronegative archive of Odessa observatory. Large surveys with small telescopes
    (2019) Kashuba, S. V.; Bazyey, N. V.; Kashuba, V. I.; Andrievsky, Serhii M.; Андрієвський, Сергій Михайлович; Андриевский, Сергей Михайлович
    Currently Observatory of I. I. Mechnikov Odessa National University owns collections of astronegatives obtained with its own instruments (about 100000 glass plates), as well as those obtained with instruments from other observatories (about 10000 plates). According to Bulgarian web-page WFPDB (wfpdb.org) Odessa collection of astroplates is second in Europe (after Sonneberg collection) and third in the world (after Harvard and Sonneberg). In this poster we describe the current condition of our collection and consider our plans for how to maintain this important astronomical heritage. We are also discussing our first steps in digitizing part of a collection in accordance with the decision of the world virtual observatory and WFPDB standards.

    Investigation of diffuse interstellar bands of organic molecules in the spectra of cepheid stars
    (Одеський національний університет імені І. І. Мечникова, 2015) Kashuba, S. V.; Andrievsky, Serhii M.; Chekhonadskikh, F. A.; Korotin, S. A.; Kovtyukh, Valery V.; Luck, R. E.; Андрієвський, Сергій Михайлович; Андриевский, Сергей Михайлович
    We describe an effective method of investigation of the Diffuse Interstellar Bands (DIBs) in the spectra of Cepheid stars. DIBs are believed to originate from the absorption of such carriers as polycyclic aromatic hydrocarbons in the interstellar gaseous clouds located between an observer and the stars whose spectra were recorded. We performed a detailed consideration of the DIB at 6613 A in our sample of spectra for more than 250 stars. The quantitative characteristics of the DIB absorption features will be studied in connection with the interstellar absorption data, and after that, they will be used in the mapping of the Galactic disc.

    Monitoring of space objects using Odessa Observatory network of telescope
    (2019) Andrievsky, Serhii M.; Bazyey, N. V.; Zhukov, V. V.; Koshkin, Nikolay I.; Kashuba, V. I.; Kashuba, S. V.; Gorbanev, Yuriy M.; Sukhov, P. P.; Podlesnyak, S. V.; Udovichenko, S. N.; Keir, L.

    In this paper we are presenting optical telescopes of Astronomical Observatory of I. I. Mechnikov Odessa National University. We are describing technical characteristics and scientific program for each telescope. Here we also present a description of the tools with which the unique collections of astroplates were obtained under the program “The Sky Service”. Odessa Observatory (46°.28 N, 30°.45 E, altitude 64 m, observation code 086) it has several observational stations. Among them: Mayaki (46.39° N, 30°.27 E, altitude 25 m, observation code 583) and Kryzhanovka (46°.37 N, 30°.48 E, altitude 40 m, observation code A85). Both stations have a good geographical location, as well as good astroclimate (up to 200 clear nights or part of the night). Telescopes are equipped with modern CCDs and photometric light detectors. Odessa Observatory has its own mechanical and optical workshops that are used for construction the new telescopes and manufacture and repair other astronomical equipment.
