“…The photometric observations obtained in the campaign were processed by APEX-II, MuniWin, or AIP4Win software. The APEX-II package (Devyatkin et al, 2009) is completely automatic and has many options for the processing of astrometric and photometric observations. This package allows the use of aperture photometry and PSF photometry (PSF fitting).…”

In this work, we present transit timing variations detected for the exoplanet TrES-5b. To obtain the necessary amount of photometric data for this exoplanet, we have organized an international campaign to search for exoplanets based on the Transit Timing Variation method (TTV) and as a result of this we collected 30 new light curves, 15 light curves from the Exoplanet Transit Database (ETD) and 8 light curves from the literature for the timing analysis of the exoplanet TrES-5b. We have detected timing variations with a semi-amplitude of A ≈ 0.0016 days and a period of P ≈ 99 days. We carried out the N-body modeling based on the three-body problem. The detected perturbation of TrES-5b may be caused by a second exoplanet in the TrES-5 system. We have calculated the possible mass and resonance of the object: M ≈ 0.24MJup at a 1:2 Resonance.

“…A total of 832 observations were made by the Pulkovo Observatory; this was about 77% of all observations. At the Pulkovo Observatory observations were carried out from December 8-12, 2009 with the MTM 500M meniscus telescope (Kul ish et al, 2009) mounted on the territory of the Kislo vodsk solar station of the Central Astronomical Obser vatory of the Russian Academy of Sciences (CAO RAS), as well as with the ZA 320M mirror astrograph (Devyatkin et al, 2004;Devyatkin et al, 2009) from December 16-21, 2009. The astrometric and photo metric processing of the 2009 WZ104 asteroid obser vations was performed using the APEX II software system (Devyatkin et al, 2007;2010).…”

The astrometric and photometric observations of the potentially hazardous 2009 WZ104 asteroid were carried out at the MTM 500M and ZA 320M automatic telescopes of the Pulkovo Observatory in December 2009. A total of 686 observations were performed in the integral band and 146 observations with B, V, R, and I filters on an arc of the orbit of 17°; these accounted for about 77% of all worldwide observations (http://www.minorplanetcenter.org/iau/ECS/MPCOBS/MPCOBS.html).On the basis of the obtained data, the orbit was improved and an estimation of the physical parameters of the asteroid was made. Estimates of the absolute stellar magnitude of the asteroid, H = (20.52 ± 0.04) m , as well as its size and mass, were obtained. The taxonomic class of the 2009 WZ104 asteroid (R or Q) was determined. A frequency analysis of the series of observations was carried out; periodicities in the asteroid's light variation were revealed using this method.
