Polarimetry of M-type asteroids in the context of their surface composition
I. Belskaya, A. Berdyugin, Yu. Krugly +9
Aims. We aim to investigate how polarimetric observations can improve our understanding of the nature and diversity of M/X-type asteroids. Methods. Polarimetric observations of the…
Orbital variability of the optical linear polarization of the -ray binary LS I +61 303 and new constraints on the orbital parameters
Vadim Kravtsov, Andrei V. Berdyugin, Vilppu Piirola +8
We studied the variability of the linear polarization and brightness of the -ray binary LS I +61 303. High-precision BVR photopolarimetric observations were carried out with the…
Disc and wind in black hole X-ray binary MAXIJ1820+070 observed through polarized light during its 2018 outburst
Ilia A. Kosenkov, Alexandra Veledina, Andrei V. Berdyugin +6
We describe the first complete polarimetric dataset of the entire outburst of a low-mass black hole X-ray binary system and discuss the constraints for geometry and radiative mecha…
Evidence for a rapid decrease in Pluto's atmospheric pressure revealed by a stellar occultation in 2019
K Arimatsu, G. L. Hashimoto, M. Kagitani +4
We report observations of a stellar occultation by Pluto on 2019 July 17. A single-chord high-speed (time resolution s) photometry dataset was obtained with a CMOS camera mo…
High-precision polarimetry of nearby stars (d<50 pc) Mapping the interstellar dust and magnetic field inside the Local Bubble
V. Piirola, A. Berdyugin, P. C. Frisch +6
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 cir…
Authenticating the Presence of a Relativistic Massive Black Hole Binary in OJ 287 Using its General Relativity Centenary Flare: Improved Orbital Parameters
Lankeswar Dey, M. J. Valtonen, A. Gopakumar +5
Results from regular monitoring of relativistic compact binaries like PSR 1913+16 are consistent with the dominant (quadrupole) order emission of gravitational waves (GWs). We show…
