Comet 81/P Wild 2: changes in the spin axis orientation during the last five apparitions
V. Oldani, F. Manzini, P. Ochner +8
Comet 81P (Wild 2) is characterized by the presence of a prominent-fan shaped dust emission originating from an active source at high latitude on the nucleus, whose axis is assumed…
Radial Distribution of the Dust Comae of Comets 45P/Honda-Mrkos-Pajduusáková and 46P/Wirtanen
C. Lejoly, W. Harris, N. Samarasinha +21
There was an unprecedented opportunity to study the inner dust coma environment, where the dust and gas are not entirely decoupled, of comets 45P/Honda-Mrkos-Pajduusáková (45P/HMP)…
Coma morphology and dust emission pattern of comet C/2020 F3 (NEOWISE)
F. Manzini, V. Oldani, P. Ochner +4
The recent close approach of comet C/2020 F3 (NEOWISE) allowed us to study the morphology of its inner coma. From the measurement of the dust ejection velocityon spiral structures…
Properties of slowly rotating asteroids from the Convex Inversion Thermophysical Model
A. Marciniak, J. Ďurech, V. Alí-Lagoa +73
Results from the TESS mission showed that previous studies strngly underestimated the number of slow rotators, revealing the importance of studying those asteroids. For most slowly…
Interstellar Comet 2I/Borisov exhibits a structure similar to native Solar System comets
F. Manzini, V. Oldani, P. Ochner +2
We processed images taken with the Hubble Space Telescope (HST) to investigate any morphological features in the inner coma suggestive of a peculiar activity on the nucleus of the…
Thermal properties of slowly rotating asteroids: Results from a targeted survey
A. Marciniak, V. Alí-Lagoa, T. G. Müller +51
Context. Earlier work suggests that slowly rotating asteroids should have higher thermal inertias than faster rotators because the heat wave penetrates deeper into the sub-surface.…
Asteroid pairs: a complex picture
P. Pravec, P. Fatka, D. Vokrouhlický +45
We studied 93 asteroid pairs. We estimated times elapsed since separation of pair members that are between 7*10^3 and a few 10^6 yr. We derived the rotation periods for all the pri…
Photometric survey, modelling, and scaling of long-period and low-amplitude asteroids
A. Marciniak, P. Bartczak, T. Müller +40
The available set of spin and shape modelled asteroids is strongly biased against slowly rotating targets and those with low lightcurve amplitudes. As a consequence of these select…
Shape and spin determination of Barbarian asteroids
M. Devogèle, P. Tanga, P. Bendjoya +51
Context. The so-called Barbarian asteroids share peculiar, but common polarimetric properties, probably related to both their shape and composition. They are named after (234) Barb…
Spin states of asteroids in the Eos collisional family
J. Hanuš, M. Delbo', V. Alí-Lagoa +33
Eos family was created during a catastrophic impact about 1.3 Gyr ago. Rotation states of individual family members contain information about the history of the whole population. W…
New and updated convex shape models of asteroids based on optical data from a large collaboration network
J. Hanuš, J. Ďurech, D. A. Oszkiewicz +165
Asteroid modeling efforts in the last decade resulted in a comprehensive dataset of almost 400 convex shape models and their rotation states. This amount already provided a deep in…
The non-convex shape of (234) Barbara, the first Barbarian
P. Tanga, B. Carry, F. Colas +37
Asteroid (234) Barbara is the prototype of a category of asteroids that has been shown to be extremely rich in refractory inclusions, the oldest material ever found in the Solar Sy…
Comet McNaught (260P/2012 K2): spin axis orientation and rotation period
Federico Manzini, Virginio Oldani, Roberto Crippa +5
Extensive observations of comet 260P (McNaught) were carried out between August 2012 and January 2013. The images obtained were used to analyze the inner coma morphology of the com…
Asteroids' physical models from combined dense and sparse photometry and scaling of the YORP effect by the observed obliquity distribution
J. Hanuš, J. Ďurech, M. Brož +116
The larger number of models of asteroid shapes and their rotational states derived by the lightcurve inversion give us better insight into both the nature of individual objects and…
Comet Machholz (C/2004 Q2): morphological structures in the inner coma and rotation parameters
Federico Manzini, Raoul Behrend, Lorenzo Comolli +6
Extensive observations of comet C/2004 Q2 (Machholz) were carried out between August 2004 and May 2005. The images obtained were used to investigate the comet's inner coma features…
New insights on the binary asteroid 121 Hermione
P. Descamps, F. Marchis, J. Durech +29
We report on the results of a six-month photometric study of the main-belt binary C-type asteroid 121 Hermione, performed during its 2007 opposition. We took advantage of the rare…
