Comparative study of activity of the near-parabolic orbitcomet C/1977 R1 (Kohler)
de Almeida, A. A.; Sanzovo, G. C.; de Araújo, L. F.
Kohler is considered a case of young, nearly parabolic comet. In this work we deduce, semi-empirically, water and hydroxyl production rates from the photometric observations of this comet taken from the Archive of Photometric Data on Comets and British Astronomical Society archives. Our results are being compared with those obtained from radio obs…
Gaia DR2 and Serbian-Bulgarian investigations
Damljanović, Goran
On April $25^{th}$ 2018, the second release of the Gaia catalog (DR2) appeared. It is based on 640 days of Gaia satellite observations; GAIA means Global Astrometric Interferometer for Astrophysics. The observing period was August $22^{nd}$ 2014 - May $23^{rd}$ 2016 (1.75 yr or 21 months with some interruptions). The reference epoch is J2015.5 . T…
An AGB Star with a Thick Circumstellar Shell
Wang, Lifan; Durré, Mark; Mould, Jeremy +1 more
The Asymptotic Giant Branch is the terminal phase of red giant evolution with timescales of millions of years and a total mass lost from the star that is a significant fraction of the initial mass. Investigation of one of these stars, WISEA J173046.10-344455.5, a kpc in the direction of the center of the Galaxy, reveals a cool oxygen rich star wit…
Observational signs of wide binary stars dissolution in Gaia DR2 data
Kovaleva, D. A.; Sapozhnikov, S. A.
Binary and common proper motion stars within 100 pc of the Sun are being investigated using Gaia DR2 data. An artificial random pairs sample is constructed to exclude possible random pairing contamination. Numerical estimation of this contamination shows that the chosen method to select the common proper motion stars yields little contamination ev…

The Orion luminosity/mass function revisited
Peña Ramírez, K.
I present an analysis of the luminosity/mass function of the largest groups identified towards the Orion Complex. Those groups were determined using spectroscopic and astrometric data from APOGEE-2 and Gaia DR2 by applying a hierarchical clustering algorithm to the six-dimensional stellar data. I used Gaussian mixture models to represent the sampl…
Software for Search and Measuring of WDS Catalog Double and Multiple Stars from Database of Results of CCD Observation
Protsyuk, Yu. I.; Maigurova, N. V.
Double and multiple star systems are the source of unique information for determining the parameters of star formation models and for testing stellar models evolution. Therefore observations and measuring of their mutual configuration parameters is still important. Observations of double and multiple star systems at the Research Institute "Mykolai…
Study of Faint Galactic Carbon Stars from the First Byurakan Spectral Sky Survey. IV. GAIA DR2 Data
Kostandyan, G. R.
Data from the second Gaia release (Gaia DR2) are used to analyze and evaluate several important parameters for 127 carbon (C) stars of which 56 are AGB stars of class N and 71 are giants of early CH classes detected in low-dispersion spectral plates from the First Byurakan Survey (FBS). For the FBS C-stars Gaia DR2 G broad – band magnitudes are in…
Cellular processes involved in lung cancer cells exposed to direct current electric field
Li, Huijuan; Liu, Shibin; Yang, Xue +4 more
With the rapid breakthrough of electrochemical treatment of tumors, electric field (EF)-sensitive genes, previously rarely exploited, have become an emerging field recently. Here, we reported our work for the identification of EF-sensitive genes in lung cancer cells. The gene expression profile (GSE33845), in which the human lung cancer CL1-0 cell…
