Absolute colors and phase coefficients of asteroids
A. Alvarez-Candal, S. Jiménez Corral, M. Colazo
Context: We use phase curves of small bodies to measure absolute magnitudes and, together with complementary theoretical and laboratory results, to understand their surfaces' micro…

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…

Zero-phase angle asteroid taxonomy classification using unsupervised machine learning algorithms
M. Colazo, A. Alvarez-Candal, R. Duffard
We are in an era of large catalogs and, thus, statistical analysis tools for large data sets, such as machine learning, play a fundamental role. One example of such a survey is the…
