Description
The Advanced LIGO observatory recently reported the first direct
detection of the gravitational waves (GWs) predicted by Einstein &
Sitzungsber. We report on the first optical observations of the GW
source GW150914 error region with the Global MASTER Robotic Net. Between
the optical telescopes of electromagnetic support, the covered area is
dominated by MASTER with an unfiltered magnitude up to 19.9 mag
(5σ). We detected several optical transients, which proved to be
unconnected with the GW event. The main input to investigate the final
error box of GW150914 was made by the MASTER-SAAO robotic telescope,
which covered 70 per cent of the final GW error box and 90 per cent of
the common localization area of the LIGO and Fermi events. Our result is
consistent with the conclusion (Abbott et al. 2016a) that GWs from
GW150914 were produced in a binary black hole merger. At the same time,
we cannot exclude that MASTER OT J040938.68-541316.9 exploded on 2015
September 14.

Very Low Mass Stars, Brown Dwarfs and Planets
Our goal is to study the processes that lead to the formation of low mass stars, brown dwarfs and planets and to characterize the physical properties of these objects in various evolutionary stages. Low mass stars and brown dwarfs are likely the most numerous type of objects in our Galaxy but due to their low intrinsic luminosity they are not so

Observational Tests of the Processes of Nucleosynthesis in the Universe
Several spectroscopic analyses of stars with planets have recently been carried out. One of the most remarkable results is that planet-harbouring stars are on average more metal-rich than solar-type disc stars. Two main explanations have been suggested to link this metallicity excess with the presence of planets. The first of these, the “self
