The spin state of asteroid Apophis and a prediction of its change during the 2029 close encounter with Earth

J. Durech, D. Vokrouhlicky, P. Pravec +23

On April 13, 2029, the asteroid Apophis will pass near Earth at a geocentric distance of about 38,000 km. Numerical models have suggested that the post-encounter spin state will cr…

Asteroid sizes determined with thermophysical model and stellar occultations

A. Choukroun, A. Marciniak, J. Ďurech +165

Context. The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability of…

Shape and spin-state model of tumbling asteroid (319) Leona

J. Ďurech, J. L. Ortiz, M. Ferrais +14

Stellar occultations by asteroids observed from several stations are routinely used to reconstruct the asteroid's sky-plane projections. Together with the asteroid's shape model re…

Scaling slowly rotating asteroids by stellar occultations

A. Marciniak, J. Ďurech, A. Choukroun +176

As evidenced by recent survey results, majority of asteroids are slow rotators (P>12 h), but lack spin and shape models due to selection bias. This bias is skewing our overall unde…

A large topographic feature on the surface of the trans-Neptunian object (307261) 2002 MS measured from stellar occultations

F. L. Rommel, F. Braga-Ribas, J. L. Ortiz +201

This work aims at constraining the size, shape, and geometric albedo of the dwarf planet candidate 2002 MS4 through the analysis of nine stellar occultation events. Using multichor…

Reaching sub-millisecond accuracy in stellar occultations and artificial satellites tracking

K. Kamiński, C. Weber, A. Marciniak +2

In recent years there appeared a need for astronomical observations timed with sub-millisecond accuracy. These include e.g. timing stellar occultations by small, sub-km or fast Nea…
