AT2021uey: A planetary microlensing event outside the Galactic bulge
M. Ban, P. Voloshyn, R. Adomaviciene +42
We report the analysis of a planetary microlensing event AT2021uey. The event was observed outside the Galactic bulge and was alerted by both space- (Gaia) and ground-based (ZTF an…
Size, albedo and rotational period of the Hayabusa2# target (98943) 2001 CC21
S. Fornasier, E. Dotto, P. Panuzzo +8
This study aims to determine the size, albedo and rotational period of (98943) 2001 CC21, target of the Hayabusa2 extended mission, using thermal data from the Spitzer Space telesc…
Rotation acceleration of asteroids (10115) 1992 SK, (1685) Toro, and (1620) Geographos due to the YORP effect
J. Durech, D. Vokrouhlicky, P. Pravec +28
The rotation state of small asteroids is affected by the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect, which is a net torque caused by solar radiation directly reflected and…
Photometry of selected outer main belt asteroids
V. Shevchenko, O. Mikhalchenko, I. Belskaya +17
We present new photometric observations for twelve asteroids ((122) Gerda, (152) Atala, (260) Huberta, (665) Sabine, (692) Hippodamia, (723) Hammonia, (745) Mauritia, (768) Struvea…
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…
A satellite orbit drift in binary near-Earth asteroids (66391) 1999 KW4 and (88710) 2001 SL9 -- Indication of the BYORP effect
P. Scheirich, P. Pravec, P. Kušnirák +34
We obtained thorough photometric observations of two binary near-Earth asteroids (66391) Moshup = 1999 KW4 and (88710) 2001 SL9 taken from 2000 to 2019 and derived physical and dyn…
Long-term photometric monitoring of the dwarf planet (136472) Makemake
T. A. Hromakina, I. N. Belskaya, Yu. N. Krugly +17
We studied the rotational properties of the dwarf planet Makemake. The photometric observations were carried out at different telescopes between 2006 and 2017. Most of the measurem…
Sectoral r modes and periodic RV variations of Sun-like stars
A. F. Lanza, L. Gizon, T. V. Zaqarashvili +2
Radial velocity (RV) measurements are used to search for planets orbiting late-type main-sequence stars and confirm the transiting planets. The most advanced spectrometers are appr…
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…
YORP and Yarkovsky effects in asteroids (1685) Toro, (2100) Ra-Shalom, (3103) Eger, and (161989) Cacus
J. Durech, D. Vokrouhlicky, P. Pravec +22
The rotation states of small asteroids are affected by a net torque arising from an anisotropic sunlight reflection and thermal radiation from the asteroids' surfaces. On long time…
Nonlinear transverse cascade and sustenance of MRI-turbulence in Keplerian disks with an azimuthal magnetic field
D. Gogichaishvili, G. Mamatsashvili, W. Horton +2
We investigate magnetohydrodynamic turbulence driven by the magnetorotational instability (MRI) in Keplerian disks with a nonzero net azimuthal magnetic field using shearing box si…
Visco-rotational shear instability of Keplerian granular flows
Luka G. Poniatowski, Alexander G. Tevzadze
The linear stability of viscous Keplerian flow around a gravitating center is studied using the rheological granular fluid model. The linear rheological instability triggered by th…
The astrometric Gaia-FUN-SSO observation campaign of 99 942 Apophis
W. Thuillot, D. Bancelin, A. Ivantsov +71
Astrometric observations performed by the Gaia Follow-Up Network for Solar System Objects (Gaia-FUN-SSO) play a key role in ensuring that moving objects first detected by ESA's Gai…
Planetesimal formation in self-gravitating discs -- dust trapping by vortices
P. G. Gibbons, G. R. Mamatsashvili, W. K. M. Rice
The mechanism through which meter-sized boulders grow to km-sized planetesimals in protoplanetary discs is a subject of active research, since it is critical for planet formation.…
