Description

There are several types of Galactic sources that can potentially accelerate charged particles up to GeV and TeV energies and through various interaction processes like for example inverse compton scattering or hadronic interactions produce Very High Energy (VHE, E>100 GeV) gamma-ray emission. We summarize recent studies based on observations with the MAGIC telescopes of gamma-ray binaries, microquasars and the subclass of binary systems known as novae. We focus on LS I +61º303, V404 Cyg, SS433 and several novae. The binary system LS I +61º303 has been observed by MAGIC over a period of 8 years in a long-term monitoring campaign. We show the newest results of our search for superorbital variability also in context of contemporaneous optical observations. The microquasar V404 Cyg has been observed with MAGIC after it went through a series of exceptional X-ray outbursts in June 2015. Using a similar follow-up strategy MAGIC observed several novae that were triggered through activity in the optical waveband. Apart from these studies, we will also present the results of MAGIC observations of the only super-critical accretion system known in our galaxy, SS 433.
