Autor: E. Vchkova-Bebekovska, N. Todorovic, A. Kostov, Z. Donchev, G. Borisov, G. Apostolovska

Publikováno v: Serbian Astronomical Journal, Vol 2021, Iss 202, Pp 39-49 (2021)

The asteroid (1986 QY4) 4940 Polenov is the first Solar system object whose 3D shape is determined using the observations from the newly built Astronomical Station Vidojevica (ASV). Here we present the results of photometric observations for Polenov,

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 selected M/X-type asteroids were carried out at the Tohoku 0.6-m tele

Rotation acceleration of asteroids (10115) 1992 SK, (1685) Toro, and (1620) Geographos due to the YORP effect

Context. The rotation state of small asteroids is affected by the Yarkovsky–O’Keefe–Radzievskii–Paddack (YORP) effect, which is a net torque caused by solar radiation directly reflected and thermally reemitted from the surface. Due to this ef

Context. EE Cep is one of few eclipsing binary systems with a dark, dusty disk around an invisible object similar to {\epsilon} Aur. The system is characterized by grey and asymmetric eclipses every 5.6 yr, with a significant variation in their photo

Asteroid clusters similar to asteroid pairs

Publikováno v: Icarus. 304:110-126

We studied the membership, size ratio and rotational properties of 13 asteroid clusters consisting of between 3 and 19 known members that are on similar heliocentric orbits. By backward integrations of their orbits, we confirmed their cluster members

Asteroid collisions as origin of debris disks: Asteroid shape reconstruction from BNAO Rozhen photometry

Autor: Andon Kostov, G. Apostolovska, Z. Donchev, E. Vchkova Bebekovska

Publikováno v: Proceedings of the International Astronomical Union. 15:451-453

As a result of collisions during their lifetimes, asteroids have a large variety of different shapes. It is believed that high velocity collisions or rotational spin-up of asteroids continuously replenish the Sun’s zodiacal cloud and debris disks a

The latest spectral analysis on asteroids at NAO Rozhen

Autor: G. Apostolovska, Z. Donchev, Galin Borisov, Elena Vchkova Bebekovska

Publikováno v: Proceedings of the International Astronomical Union. 15:448-450

By virtue of the physical, chemical and dynamical characteristics of asteroids, researchers gain insight into the formation and evolution of our Solar system. Since these objects do not undergo any changes, or the changes during the Solar system evol

Aims. The orbital motion of the transiting hot Jupiter TrES-5 b was reported to be perturbed by a planetary companion on a nearby orbit. Such compact systems do not frequently occur in nature, and investigating their orbital architecture could shed s
