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…
The MDOR/PDOR on-line module for MISO, the planning software of Solar Orbiter instruments
Susino, Roberto; Antonucci, Ester; Fineschi, Silvano +24 more
Solar Orbiter is a solar mission that will approach the Sun down to a minimum perihelion of 0.28 AU and will increase its orbit inclination with respect to the ecliptic up to a maximum angle of 34 deg. For imagers aboard Solar Orbiter there will be three 10-days remote sensing windows per orbit. Observations shall be carefully planned at least 6 m…
MACHO 311.37557.169: A VY Scl star
Brown, Michael J. I.; Schwope, Axel D.; Traulsen, Iris +1 more
Optical surveys, such as the MACHO project, often uncover variable stars whose classification requires follow‑up observations by other instruments. We performed X‑ray spectroscopy and photometry of the unusual variable star MACHO 311.37557.169 with XMM‑Newton in April 2018, supplemented by archival X‑ray and optical spectrographic data. The star h…
Landing site characterization for Tsiolkovskiy crater
Massironi, Matteo; Pozzobon, Riccardo; Tognon, Gloria
On the southern hemisphere of the lunar farside lies the interesting Tsiolkovskiy crater that presents on its floor one of the few exposures of mare volcanism on the far side and an unusually well-shaped central peak.Its morphology and the remotely-sensed detection of minerals such as olivine and Purest Anorthosite (PAN), make Tsiolkovskiy crater …
