Observations of Exocomets
Judith Korth, Azib Norazman, Raphäel Bendahan-West +6
Active small bodies in extrasolar systems, the extrasolar analogues of Solar System comets, provide insights into the orbital evolution and physical processes shaping planetary sys…
Dust, gas activity and morphology of comet 12P/Pons-Brooks at heliocentric distances beyond 1.1 au
Marek Husárik, Gulchehra Kokhirova, Valerii Kleshchonok +6
Comet 12P/Pons-Brooks is a periodic comet with an orbital period of approximately 71 years. Because of the period duration, aphelion of 35.3 au, and highly inclined orbit (74.2 deg…
Numerical simulations of exocomet transits: Insights from \{beta} Pic and KIC 3542116
I. Luk'yanyk, I. Kulyk, O. Shubina +4
In recent years, the topic of existence and exploration of exocomets has been gaining increasing attention. The asymmetrical decrease in the stellar brightness due to the passage o…
Photometry of comet 29P/Schwassmann-Wachmann 1 in 2012-2019
Olena Shubina, Valery Kleshchonok, Oleksandra Ivanova +2
The analysis of photometrical observations of comet 29P/Schwassmann-Wachmann 1 is presented. The broadband observations were carried out for 15 nights from 2012 to 2019 at the Lisn…
Long-lasting activity of asteroid (248370) 2005 QN 173
Oleksandra Ivanova, Javier Licandro, Fernando Moreno +8
We present the results of observations of asteroid (248370) QN obtained during July 2021 - January 2022 with three telescopes. Our analysis revealed the presence of the dus…
New exocomets of Pic
Ya. Pavlenko, I. Kulyk, O. Shubina +3
Aims. The aim of our work is to analyze the light curves of Pic recently observed by TESS in sectors 32, 33, and 34, searching for the signatures of exocomet transits. Methods.…
Comet 2P/Encke in apparition of 2017: II. Polarization and color
Nikolai Kiselev, Vera Rosenbush, Oleksandra Ivanova +5
We present results of imaging polarimetry of comet 2P/Encke performed on January 23, 2017 at the heliocentric (1.052 au) and geocentric (1.336 au) distances and phase angle 46.8 de…
Comet 2P/Encke in apparitions of 2013 and 2017: I. Imaging photometry and long-slit spectroscopy
Vera Rosenbush, Oleksandra Ivanova, Valerii Kleshchonok +4
We present the results of imaging photometric and long-slit spectroscopic observations of comet 2P/Encke performed at the heliocentric distance 0.56 au, geocentric distance 0.65 au…
Color variations of Comet C/2013 UQ4 (Catalina)
Oleksandra Ivanova, Evgenij Zubko, Gorden Videen +7
We report observations of color in the inner coma of Comet C/2013 UQ4 (Catalina) with the broadband B and R filters. We find significant temporal variations of the color slope, ran…
Polarimetric and Spectroscopic Observations of a Dynamically New Comet C/2012 J1 (Catalina)
O. Ivanova, O. Shubina, A. Moiseev +1
We present the analysis of the polarimetric and spectral data obtained for the dynamically new comet C/2012\,J1 (Catalina) when it was at a distance of 3.17~AU from the Sun. The ob…
