  • The astrometric Gaia-FUN-SSO observation campaign of 99942 Apophis 
    Thuillot W.; Bancelin D.; Ivantsov A.; Desmars J.; Assafin M.; Eggl S.; Hestroffer D.; Rocher P.; Carry B.; David P.; Abe L.; Andreev M.; Arlot J.; Asami A.; Ayvasian V.; Baransky A.; Belcheva M.; Bendjoya P.; Bikmaev I.; Burkhonov O.; Camci U.; Carbognani A.; Colas F.; Devyatkin A.; Ehgamberdiev S.; Enikova P.; Eyer L.; Galeev A.; Gerlach E.; Godunova V.; Golubaev A.; Gorshanov D.; Gumerov R.; Hashimoto N.; Helvaci M.; Ibryamov S.; Inasaridze R.; Khamitov I.; Kostov A.; Kozhukhov A.; Kozyryev Y.; Krugly Y.; Kryuchkovskiy V.; Kulichenko N.; Maigurova N.; Manilla-Robles A.; Martyusheva A.; Molotov I.; Nikolov G.; Nikolov P.; Nishiyama K.; Okumura S.; Palaversa L.; Parmonov O.; Peng Q.; Petrova S.; Pinigin G.; Pomazan A.; Rivet J.; Sakamoto T.; Sakhibullin N.; Sergeev O.; Sergeyev A.; Shulga O.; Suarez O.; Sybiryakova Y.; Takahashi N.; Tarady V.; Todd M.; Urakawa S.; Uysal O.; Vaduvescu O.; Vovk V.; Zhang X. (2015)
    © 2015 ESO. Aims. Astrometric observations performed by the Gaia Follow-Up Network for Solar System Objects (Gaia-FUN-SSO) play a key role in ensuring that moving objects first detected by ESA's Gaia mission remain recoverable ...
  • The atmospheres and spectra of X-ray illuminated stars: Line formation 
    Sakhibullin N.; Shimanskii V. (1997)
    The formation of lines in X-ray illuminated atmospheres and in close binary systems with X-ray sources is studied. It is shown that there are three groups of lines: "cool" (absorption lines), "normal" (absorption lines ...
  • The evolutionary status of UX CVn 
    Shimansky V.; Borisov N.; Sakhibullin N.; Suleimanov V.; Stupalov M. (2002)
    We have analyzed available spectroscopic and photometric observations of the close binary UX CVn using model atmospheres. Theoretical spectra and light curves were derived from models of a precataclysmic variable and a ...
  • The First Hours of the Optical Afterglow from the Cosmic Gamma-Ray Burst 030329 
    Burenin R.; Sunyaev R.; Pavlinsky M.; Denisenko D.; Terekhov O.; Tkachenko A.; Aslan Z.; Khamitov I.; Uluch K.; Alpar M.; Kiziloglu U.; Baikal A.; Bikmaev I.; Sakhibullin N.; Suleymanov V. (2003)
    We describe the first results of our observations of the exceptionally bright optical afterglow from the cosmic gamma-ray burst (GRB) of March 29, 2003 (030329), with the 1.5-m Russian-Turkish telescope (RTT 150) installed ...
  • The nature of the unique precataclysmic variable V664 Cas with two-peaked balmer lines in its spectrum 
    Shimanskiǐ V.; Borisov N.; Sakhibullin N.; Surkov A. (2004)
    We analyze photometric and spectroscopic observations of the close binary system V664 Gas. All the characteristics of its radiation are consistent with the star being a cataclysmic variable with powerful reflection effects. ...
  • The new pre-cataclysmic binary PG 2200+085 
    Shimansky V.; Sakhibullin N.; Bikmaev I.; Ritter H.; Suleimanov V.; Borisov N.; Galeev A. (2006)
    Aims. We present the results of spectroscopic- and orbit-sampled photometric observations of the faint UV-excess object PG 2200+085. Methods. The optical CCD photometry observations of this object were performed by the ...
  • Type Ia supernovae 2014J and 2011fe at the nebular phase 
    Bikmaev I.; Chugai N.; Sunyaev R.; Churazov E.; Khamitov I.; Sakhibullin N.; Galeev A.; Akhmetkhanova A. (2015)
    © 2015, Pleiades Publishing, Inc. We present our observations and the results of our analysis of the nebular spectra for two nearby type Ia supernovae (SN 2014J and SN 2011fe). For the overall picture, we have analyzed the ...
  • V1327 aquilae: A new RR lyrae variable with an extremely high radial velocity 
    Galeev A.; Bikmaev I.; Borisov N.; Zhuchkov R.; Shimanskii V.; Khabibullina M.; Sakhibullin N. (2008)
    We have carried out photometry and spectroscopy of the star V1327 Aql (R = 16 m ) as part of our program of observations of poorly studied cataclysmic variables using the 1.5-m optical Russian-Turkish telescope (RTT-150, ...
  • Variability of X-ray pulsars in a hard energy band observed with INTEGRAL 
    Lutovinov A.; Tsygankov S.; Revnivtsev M.; Chernyakova M.; Bikmaev I.; Molkov S.; Burenin R.; Pavlinsky M.; Sakhibullin N. (2004)
    We present the first results of the observations of the X-ray pulsars LMC X-4, 4U0352+309 and EXO1722-363 performed with the INTEGRAL observatory. The LMC X-4 was investigated during the whole superorbital cycle (∼30 days) ...
