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.…
Observations of the long-lasting activity of the distant Comets 29P Schwassmann-Wachmann 1, C/2003 WT42 (LINEAR) and C/2002 VQ94 (LINEAR)
Oleksandra Ivanova, Yury Skorov, Pavlo Korsun +2
We investigated three comets, which are active at large heliocentric distances, using observations obtained at the 6-m BTA telescope (SAO RAS, Russia) in the photometric mode of th…
Distant Jupiter family Comet P/2011 P1 (McNaught)
Pavlo Korsun, Oleksandra Ivanova, Viktor Afanasiev +1
The spectra and images obtained through broadband BVR filters for Jupiter famaly comet P/2011 P1 were analyzed. We observed the comet on November 24, 2011, when its heliocentric di…
Photometric investigations of distant comets C/2002 VQ94 (LINEAR) and 29P/Schwassmann-Wachmann-1
A. V. Ivanova, P. P. Korsun, V. L. Afanasiev
We present an analysis of the results of photometric investigations of two distant comets, C/2002 VQ94 (LINEAR) and 29P/Schwassmann-Wachmann 1, obtained with the 6m telescope of th…
The Rotation Period of Comet 29P/Schwassmann-Wachmann 1 Determined from the Dust Structures (Jets) in the Coma
A. V. Ivanova, V. L. Afanasiev, P. P. Korsun +3
The results of the photometric observations of comet 29P/Schwassmann-Wachmann 1 are analyzed. The comet demonstrates substantial activity at heliocentric distances larger than 5 AU…
The optical characteristics of the dust of sungrazing comet C/2012 S1 (ISON) observed at large heliocentric distances
Oleksandra Ivanova, Volodymyr Reshetnyk, Yury Skorov +7
We present an analysis of the photometric and spectroscopic data of the comet C/2012 S1 (ISON) observed at the heliocentric distances of 6.21÷4.81 AU. The photometric observations…
Observations of Comets C/2007 D1 (LINEAR), C/2007 D3 (LINEAR), C/2010 G3 (WISE), C/2010 S1 (LINEAR), and C/2012 K6 (McNaught) at large heliocentric distances
Oleksandra Ivanova, Luboš Neslušan, Zuzana Seman Krišandova +5
Photometric and spectroscopic observations of five nearly parabolic comets with eccentricity larger than 0.99 at heliocentric distances greater than 4 AU were performed. No molecul…
CCD polarimetry of distant comets C/2010 S1 (LINEAR) and C/2010 R1 (LINEAR) at the 6-m telescope of the SAO RAS
Oleksandra V. Ivanova, Janna M. Dlugach, Viktor L. Afanasiev +2
We present first measurements of the degree of linear polarization of distant comets C/2010 S1 (LINEAR) and C/2010 R1 (LINEAR) at heliocentric distances r= 5.9 - 7.0 AU. Observatio…
Distant activity of comet C/2002 VQ94 (LINEAR): optical spectrophotometric monitoring between 8.4 and 16.8 au from the Sun
Pavlo P. Korsun, Philippe Rousselot, Irina V. Kulyk +2
Spectrophotometric monitoring of distant comet C/2002 VQ94 (LINEAR) was performed with the 6-m telescope of SAO RAS and with the 2.5-m Nordic Optical Telescope between 2008 and 201…
