Why Do We See So Few Black Holes in Massive Binaries?

S. Karpov, V. Lipunov

We offer a simple explanation for the small number of black holes observed in pairs with massive stars. In detached massive binaries, spherically symmetric accretion takes place. T…

Contact binary asteroid (153201) 2000 WO107: rotation, shape model, and density

Yurij Krugly, Oleksiy Golubov, Ihor Kyrylenko +10

We combine different methods to investigate the rotation, determine the shape and estimate the density of near-Earth asteroid (153201) 2000 WO. We carried out photometric o…

Aerosol Measurement in B, V, and R Filters using Wide-field Photometry

Shefali Negi, Jan Ebr, Sergey Karpov +1

The new method for aerosol measurement using wide-field stellar photometry was originally developed for B-filter data. The dependence of VAOD (vertical aerosol optical depth) on wa…
