Theoretical Mass-Luminosity Relations in Gaia G-Band
Oleg Malkov, Dana Kovaleva, Aleksandr Zhukov +1
We have analyzed the retrieval of the relation between mass and absolute Gaia G magnitude as obtained from theoretical models by \cite{2012MNRAS.427..127B} for the stars of differe…
Binary Star Population with Common Proper Motion in Gaia DR2
S. A. Sapozhnikov, D. A. Kovaleva, O. Yu. Malkov +1
We describe a homogeneous catalog compilation of common proper motion stars based on Gaia DR2. A preliminary list of all pairs of stars within the radius of 100 pc around the Sun w…
Collinder 135 and UBC 7: A Physical Pair of Open Clusters
Dana Kovaleva, Marina Ishchenko, Ekaterina Postnikova +7
Given the closeness of the two open clusters Cr 135 and UBC 7 on the sky, we investigate the possibility of the two clusters to be physically related. We aim to recover the present…
Statistical relations between stellar spectral and luminosity classes and stellar effective temperature and surface gravity
O. Yu. Malkov, D. A. Kovaleva, S. G. Sichevsky +1
We have determined new statistical relations to estimate the fundamental atmospheric parameters of effective temperature and surface gravity, using MK spectral classification, and…
Verification of Photometric Parallaxes with Gaia DR2 Data
Oleg Malkov, Sergey Karpov, Dana Kovaleva +10
Results of comparison of Gaia DR2 parallaxes with data derived from a combined analysis of 2MASS (Two Micron All-Sky Survey), SDSS (Sloan Digital Sky Survey), GALEX (Galaxy Evoluti…
A preliminary comparison of photometric (MWSC) and trigonometric (TGAS) distances of open cluster stars
Dana Kovaleva, Anatoly Piskunov, Nina Kharchenko +1
Our goal was to compare the open cluster photometric distance scale of the global survey of star clusters in the Milky Way (MWSC) with the distances derived from trigonometric para…
