Abstract We present the results of prompt optical follow-up electromagnetic counterpart gravitational-wave event GW170817 by Transient Optical Robotic Observatory South Collaboration. detected highly significant dimming in light curves ( mag, mag) over course only 80 minutes observations obtained ∼35 hr after trigger with T80-South telescope. A second epoch observations, ∼59 EABA 1.5 m telescope, confirms fast fading nature transient. The observed colors suggest that this was a “blue...
This paper presents 1463 times of minima for 455 objects acquired by 46 members and cooperating observers the Variable Star Exoplanet Section Czech Astronomical Society (B.R.N.O. Observing project). Observations were carried out between October 2013 - September 2014. Some neglected southern eclipsing binaries newly discovered stars project B.R.N.O. are included in list.
We present the results of optical follow-up conducted by TOROS collaboration first gravitational-wave event GW150914. unfiltered CCD observations (0.35-1 micron) with 1.5-m telescope at Bosque Alegre starting ~2.5 days after alarm. Given our limited field view (~100 square arcmin), we targeted 14 nearby galaxies that were observable from site and located within area higher localization probability. analyzed using two independent implementations difference-imaging algorithms, followed a...
This paper presents 2109 times of minima for 965 objects acquired by 59 members and cooperating observers the Variable Star Exoplanet Section Czech Astronomical Society (B.R.N.O. Observing project).These observations were submitted to website between November 2016 March 2018.
The types of instability in the interacting binary stars are reviewed. project "Inter-Longitude Astronomy" is a series smaller projects on concrete or groups stars. It has no special funds, and supported from resources grants participating organizations, when informal working created. Totally we studied 1900+ variable different types. characteristic timescale seconds to decades (extrapolating) even more. monitoring first star our sample AM Her was initiated by Prof. V.P. Tsesevich...
We present the results of optical follow-up, conducted by TOROS collaboration, gravitational wave events detected during Advanced LIGO-Virgo second observing run (Nov 2016 -- Aug 2017). Given limited field view ($\sim100\arcmin$) our observational instrumentation we targeted galaxies within area high localization probability that were observable from sites. analyzed observations using difference imaging, followed a Random Forest algorithm to discriminate between real and bogus transients....
