Initial characterization of interstellar comet 2I/Borisov
Piotr Guzik, Michał Drahus, Krzysztof Rusek +3
Interstellar comets penetrating through the Solar System had been anticipated for decades. The discovery of asteroidal-looking 'Oumuamua was thus a huge surprise and a puzzle. Furt…
The Excited Spin State of 1I/2017 U1 `Oumuamua
Michael J. S. Belton, Olivier R. Hainaut, Karen J. Meech +15
We show that `Oumuamua's excited spin could be in a high energy LAM state, which implies that its shape could be far from the highly elongated shape found in previous studies. CLEA…
Tumbling motion of 1I/'Oumuamua reveals body's violent past
Michal Drahus, Piotr Guzik, Waclaw Waniak +3
Models of the Solar System evolution show that almost all the primitive material leftover from the formation of the planets was ejected to the interstellar space as a result of dyn…
Spiral structures and temperature distribution in the quiescent accretion disc of the cataclysmic binary V2051 Ophiuchi
Artur Rutkowski, Waclaw Waniak, George W. Preston +1
We present the capabilities of our new code for obtaining Doppler maps implementing the maximum likelihood approach. As test data, we used observations of the dwarf nova V2051 Ophi…
Fast Rotation and Trailing Fragments of the Active Asteroid P/2012 F5 (Gibbs)
Michal Drahus, Waclaw Waniak, Shriharsh Tendulkar +3
While having a comet-like appearance, P/2012 F5 (Gibbs) has an orbit native to the Main Asteroid Belt, and physically is a km-sized asteroid which recently (mid 2011) experienced a…
International observational campaigns of the last two eclipses in EE Cephei: 2003 and 2008/9
C. Gałan, M. Mikołajewski, T. Tomov +87
Two observational campaigns were carried out during the eclipses of EE Cep in 2003 and 2008/9 to verify whether the eclipsing body in the system is indeed a dark disk and to unders…
A photometric and spectroscopic study of WW And - an Algol-type, long period binary system with an accretion disc
Michal Siwak, Stanislaw Zola, Tomasz Szymanski +5
We have analyzed the available spectra of WW And and for the first time obtained a reasonably well defined radial velocity curve of the primary star. Combined with the available ra…
The Sources of HCN and CH3OH and the Rotational Temperature in Comet 103P/Hartley 2 from Time-Resolved Millimeter Spectroscopy
Michal Drahus, David Jewitt, Aurelie Guilbert-Lepoutre +2
One of the least understood properties of comets is the compositional structure of their nuclei, which can either be homogeneous or heterogeneous. The nucleus structure can be conv…
