Tumbling motion of 1I/‘Oumuamua and its implications for the body’s distant past
Models of the Solar System’s 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 dynamical…
The Excited Spin State of 1I/2017 U1 `Oumuamua
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. CLEAN and ANOVA…
THE SOURCES OF HCN AND CH3OH AND THE ROTATIONAL TEMPERATURE IN COMET 103P/HARTLEY 2 FROM TIME-RESOLVED MILLIMETER SPECTROSCOPY*
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 conveniently studied at…
Initial characterization of interstellar comet 2I/Borisov
Interstellar comets penetrating through the Solar System had been anticipated for decades 1 , 2 . The discovery of asteroidal-looking ‘Oumuamua 3 , 4 was thus a huge surprise and a puzzle.…
FAST ROTATION AND TRAILING FRAGMENTS OF THE ACTIVE ASTEROID P/2012 F5 (GIBBS)*
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 an impulsive mass…
A Monte Carlo approach to the analysis of the dust tail of comet P/Halley
Tumbling motion of 1I/'Oumuamua reveals body's violent past
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 dynamical…
Spiral structures and temperature distribution in the quiescent accretion disc of the cataclysmic binary V2051 Ophiuchi
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 Ophiuchi. The system…
Rotation of the Nucleus, Gas Kinematics and Emission Pattern of Comet 8P/Tuttle: Preliminary Results from Optical Imaging of the CN Coma
We present preliminary results of the narrow-band CN observations of comet 8P/Tuttle from early January 2008, realized as part of a project consisting of near-simultaneous spectroscopic monitoring of…
International observational campaigns of the last two eclipses in EE Cephei: 2003 and 2008/9
Context. EECep is an unusual long-period (5.6 yr) eclipsing binary discovered during the mid-twentieth century. It undergoes almost-grey eclipses that vary in terms of both depth and duration at…
