DIPol-UF: simultaneous three-color () polarimeter with EM CCDs
Vilppu Piirola, Ilia A. Kosenkov, Andrei V. Berdyugin +2
We describe a new instrument capable of high precision () polarimetric observations simultaneously in three passbands (). The instrument utilizes electron-multiplied…
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…
Colors and patterns of black hole X-ray binary GX 339-4
Ilia A. Kosenkov, Alexandra Veledina, Valery F. Suleimanov +1
Black hole X-ray binaries show signs of non-thermal emission in the optical/near-infrared range. We analyze the optical/near-infrared SMARTS data on GX3394 over the 2002--2011 p…
Evolving optical polarisation of the black hole X-ray binary MAXI J1820+070
A. Veledina, A. V. Berdyugin, I. A. Kosenkov +8
Aims. The optical emission of black hole transients increases by several magnitudes during the X-ray outbursts. Whether the extra light arises from the X-ray heated outer disc, fro…
Superhump period of the black hole X-ray binary GX 339-4
Ilia A. Kosenkov, Alexandra Veledina
We investigate variability of optical and near-infrared light curves of the X-ray binary GX 339-4 on a timescale of days. We use the data in four filters from six intervals corresp…
