Spin Change of Asteroid 2012 TC4 probably by Radiation Torques
Hee-Jae Lee, Josef Ďurech, David Vokrouhlický +9
Asteroid 2012 TC4 is a small (10 m) near-Earth object that was observed during its Earth close approaches in 2012 and 2017. Earlier analyses of light curves revealed its exci…
Asteroid models reconstructed from ATLAS photometry
J. Durech, J. Tonry, N. Erasmus +4
The Asteroid Terrestrial-impact Last Alert System (ATLAS) is an all-sky survey primarily aimed at detecting potentially hazardous near-Earth asteroids. Apart from the astrometry of…
Binary asteroid (31) Euphrosyne: Ice-rich and nearly spherical
B. Yang, J. Hanus, B. Carry +38
Asteroid (31) Euphrosyne is one of the biggest objects in the asteroid main belt and the Euphrosyne family occupies a highly inclined region in the outer main belt and contains a r…
Asteroid models from generalised projections: Essential facts for asteroid modellers and geometric inverse problem solvers
Mikko Kaasalainen, Josef Durech
We present a review of the problem of asteroid shape and spin reconstruction from generalised projections; i.e., from lightcurves, disk-resolved images, occultation silhouettes, ra…
Basis functions and uniqueness in orbit-averaged population analysis of asteroids
Mikko Kaasalainen, Josef Durech
Time-resolved photometry of asteroids can be used for shape and spin reconstruction. If the number of measurements per asteroid is not sufficient to create a model, the whole data…
Shape model and spin state of non-principal axis rotator (5247) Krylov
H. -J. Lee, J. Ďurech, M. -J. Kim +12
Context. The study of non-principal axis (NPA) rotators can provide important clues to the evolution of the spin state of asteroids. However, so far, very few studies have focused…
