Pre-perihelion observations of comet P/2023 JN16 (Lemmon) at the 2024 apparition
Serhii Borysenko, Alexander Baransky, Christopher A. Onken +1
We present an analysis of the photometric data of new main belt comet P/2023 JN16 (Lemmon) observed with the 1.35-m SkyMapper telescope at Siding Spring Observatory in 2024 during…
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…
Astrometric and photometric observations of six brightest trans-Neptunian objects at the Kyiv comet station
Alexander Baransky, Oleksandra Lukina, Serhii Borysenko
In this work, we focused on observations of six trans-Neptunian objects (TNOs) whose apparent magnitudes are brighter than 20 mag. We present the results of astrometric and photome…
Imaging polarimetry and photometry of comet 21P/Giacobini-Zinner
E. Chornaya E. Zubko, I. Luk'yanyk, A. Kochergin +8
We report results of polarimetric observations of comet 21P/Giacobini-Zinner made at phase angles, α=76-78 deg, between 10 and 17 of September 2018, and compare them with previous…
Study of the physical properties of selected active objects in the main belt and surrounding regions by broadband photometry
Serhii Borysenko, Alexander Baransky, Ekkehard Kuehrt +3
Dynamically different groups of comets and active asteroids with orbits at 2 - 5 a. u. show dust activity in varying degrees and forms. Photometric study and comparison of physical…
Potential asteroid discoveries by the ESA Gaia mission: Results from follow-up observations
B. Carry, W. Thuillot, F. Spoto +42
Since July 2014, the ESA Gaia mission has been surveying the entire sky down to magnitude 20.7 in the visible. In addition to the millions of stars, thousands of Solar System Objec…
