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…
