Modeling of 35-day superorbital cycle of and light curves of IMXB HZ Her/Her X-1
D. A. Kolesnikov, N. I. Shakura, K. A. Postnov +13
The X-ray binary Her X-1 consists of an accreting neutron star and the optical component HZ Her. The 35-day X-ray superorbital variability of this system is known since its discove…
SRG/eROSITA uncovers the most X-ray luminous quasar at z>6
P. Medvedev, S. Sazonov, M. Gilfanov +6
We report the discovery of X-ray emission from CFHQS J142952+544717, the most distant known radio-loud quasar at z=6.18, on Dec. 10--11, 2019 with the eROSITA telescope on board th…
The intermediate nebular phase of SN 2014J: onset of clumping as the source of recombination
P. A. Mazzali, I. Bikmaev, R. Sunyaev +6
At the age of about 1 year, the spectra of most Type Ia supernovae are dominated by strong forbidden nebular emission lines of FeII and FeIII. Later observations (at about 2 years)…
Full orbital solution for the binary system in the northern Galactic disc microlensing event Gaia16aye
Łukasz Wyrzykowski, P. Mróz, K. A. Rybicki +182
Gaia16aye was a binary microlensing event discovered in the direction towards the northern Galactic disc and was one of the first microlensing events detected and alerted to by the…
Spectroscopic study of the optical counterpart to the Fast X-ray Transient IGR J17544-2619 based on observations at the 1.5-m RTT-150 telescope
I. F. Bikmaev, E. A. Nikolaeva, V. V. Shimansky +7
We present the results of our long-term photometric and spectroscopic observations at the Russian-Turkish RTT-150 telescope for the optical counterpart to one of the best-known sou…
A Jupiter-mass planet around the K0 giant HD 208897
M. Yılmaz, B. Sato, I. Bikmaev +9
For over 10 years, we have carried out a precise radial velocity (RV) survey to find substellar companions around evolved G,K-type stars to extend our knowledge of planet formation…
