Transformation of Pan-STARRS1 gri to Stetson BVRI magnitudes. Photometry of small bodies observations
A. Kostov, T. Bonev
The UBVRI broad band photometric system is widely used in CCD astronomy. There are a lot of sets of standard stars for this photometric system, the Landolt's and Stetson's catalogu…
Rotation acceleration of asteroids (10115) 1992 SK, (1685) Toro, and (1620) Geographos due to the YORP effect
J. Durech, D. Vokrouhlicky, P. Pravec +28
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…
Polarimetry of M-type asteroids in the context of their surface composition
I. Belskaya, A. Berdyugin, Yu. Krugly +9
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…
Dust observations of Comet 9P/Tempel 1 at the time of the Deep Impact
G. P. Tozzi, H. Boehnhardt, L. Kolokolova +15
On 4 July 2005 at 05:52 UT, the impactor of NASA's Deep Impact (DI) mission crashed into comet 9P/Tempel 1 with a velocity of about 10 km/s. The material ejected by the impact expa…
Rotation-stimulated structures in the CN and C3 comae of comet 103P/Hartley 2 around the EPOXI encounter
W. Waniak, G. Borisov, M. Drahus +1
In late 2010 a Jupiter Family comet 103P/Hartley 2 was a subject of an intensive world-wide investigation. On UT October 20.7 the comet approached the Earth within only 0.12 AU, an…
Rotational variation of the linear polarisation of the asteroid (3200) Phaethon as evidence for inhomogeneity in its surface properties
G. Borisov, M. Devogèle, A. Cellino +23
Asteroid (3200) Phaethon is a Near-Earth Apollo asteroid with an unusual orbit that brings it closer to the Sun than any other known asteroid. Its last close approach to the Earth…
The phase-polarization curve of asteroid (3200) Phaethon
M. Devogèle, A. Cellino, G. Borisov +10
A multi-colour phase-polarization curve of asteroid (3200)~Phaethon has been obtained during the December 2017 apparition by merging measurements taken at the observing station of…

The CTA Consortium, :, O. Abril +1102
Compilation of CTA contributions to the proceedings of the 33rd International Cosmic Ray Conference (ICRC2013), which took place in 2-9 July, 2013, in Rio de Janeiro, Brazil
H-alpha spectroscopy of the recurrent nova RS Oph during the 2021 outburst
R. K. Zamanov, K. A. Stoyanov, Y. M. Nikolov +3
We report spectroscopic observations of the emission line of the recurrent nova RS~Oph obtained between 12 and 23 August 2021 during the recent outburst. On the basis of the…
