We studied the variability of the linear polarization and brightness of the γ-ray binary LS I +61° 303. High-precision BVR photopolarimetric observations were carried out with the Dipol-2 polarimeter on the 2.2 m remotely controlled UH88 telescope at Mauna Kea Observatory and the 60 cm Tohoku telescope at Haleakala bservatory (Hawaii) over 140 nights in 2016−2019. We also determined the degree and angle of the interstellar polarization toward LS I +61° 303 using two out of four nearby field… 
Radio/X-ray correlations and variability in the X-ray binary LS I +61°303
The high-mass X-ray binary LS I +61°303 exhibits variability in its radio and X-ray emissions, ranging from minute to hour time-scales. At such short time-scales, not much is known about the possible
Optical and Near-Infrared Monitoring of Gamma-ray Binaries Hosting Be Stars
Optical and near-infrared observations are compiled for the three gamma-ray binaries hosting Be stars: PSR B1259−63, LSI+61 303, and HESS J0632+057. The emissions from the Be disk are considered to
The First High-contrast Images of X-Ray Binaries: Detection of Candidate Companions in the γ Cas Analog RX J1744.7-2713
X-ray binaries provide exceptional laboratories for understanding the physics of matter under the most extreme conditions. Until recently, there were few, if any, observational constraints on the

Observation of the Gamma-Ray Binary HESS J0632+057 with the H.E.S.S., MAGIC, and VERITAS Telescopes
The results of gamma-ray observations of the binary system HESS J0632 + 057 collected during 450 hr over 15 yr, between 2004 and 2019, are presented. Data taken with the atmospheric Cherenkov
Very High-energy Gamma-ray Emission from LS I +61$^\circ$ ~303 Binary
LS I +61° 303 is one of around ten gamma-ray binaries detected so far which has a spectral energy distribution dominated by MeV-GeV photons. It is located at a distance of 2 kpc and consists of a

H-alpha observations of the gamma-ray-emitting Be/X-ray binary LSI+61303: orbital modulation, disk truncation, and long-term variability
We report 138 spectral observations of the H-alpha emission line of the radio- and gamma-ray-emitting Be/X-ray binary LSI+61303 obtained during the period of September 1998 -- January 2013. From
Associating long-term γ-ray variability with the superorbital period of LS I + 61◦ 303
Gamma-ray binaries are stellar systems for which the spectral ene rgy distribu- tion (discounting the thermal stellar emission) peaks at high energie s. Detected from radio to TeV gamma rays, the γ
Simultaneous X-Ray and Radio Monitoring of the Unusual Binary LS I +61°303: Measurements of the Light Curve and High-Energy Spectrum
The binary system, LS I +61°303, is unusual both because of the dramatic, periodic, radio outbursts, and because of its possible association with the 100 MeV gamma-ray source, 2CG 135+01. We have
High-precision polarimetry of nearby stars (d < 50 pc)
Context. We investigate the linear polarization produced by interstellar dust aligned by the magnetic field in the solar neighborhood (d < 50 pc). We also look for intrinsic effects from
Evidence of coupling between the thermal and nonthermal emission in the gamma-ray binary LS I +61 303
The gamma-ray binary LS I +61 303 is composed of a Be star and a compact companion orbiting in an eccentric orbit. Variable flux modulated with the orbital period of ~26.5 d has been detected from
Connection between orbital modulation of Hα and gamma-rays in the Be/X-ray binary LS I+61°303
We studied the average orbital modulation of various parameters (γ-ray flux, Hα emission line, optical V band brightness) of the radioand γ-ray emitting Be/ X-ray binary LS I+61 ◦ 303. Using the
Bayesian Analysis of Radio Observations of the Be X-Ray Binary LS I +61°303
The binary star LS I +61303 is remarkable for its periodic radio outbursts every 26.5 days. We recently discovered a 4.4 year periodic modulation of the phase and amplitude of these outbursts using
