The Synchronous Network of distant Telescopes

TL;DR

The Synchronous Network of distant Telescopes (SNT) is an international collaboration utilizing synchronized telescopes with standardized systems to observe and discover new phenomena in variable stars over a decade.

Contribution

This paper presents the first realization of the SNT concept, integrating multiple telescopes with synchronized timing and software for advanced astrophysical observations.

Findings

Discovery of new fine-scale features in flaring red dwarfs

Detection of flare-triggered phenomena in variable stars

Observation of high-frequency variability in chromospherically active stars

Abstract

The Synchronous Network of distant Telescopes (SNT) represents an innovative approach in observational astrophysics. Authors present the unique existing realization of the SNT-conception. It was founded within the international collaboration between astronomical observatories of Ukraine, Russia, Bulgaria and Greece. All the telescopes of the Network are equipped with standardized photometric systems (based on photomultipliers). The unified timing systems (based on GPS-receivers) synchronize all the apertures to UTC with an accuracy of 1 microsecond and better. The essential parts of the SNT are the original software for operating and data processing. Described international Network successfully works for more then 10 years. The obtained unique observational data made it possible to discover new fine-scale features and flare-triggered phenomena in flaring red dwarfs, as well as the recently found high-frequency variability in some chromospherically active stars.
