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…
Historical Surveys to Rubin First Look: Absolute Colors of trans-Neptunian objects
Milagros Colazo, Alvaro Alvarez-Candal
We present a comprehensive photometric study of trans-Neptunian objects (TNOs) by combining data from SDSS, Col-OSSOS, DES, and the recent Rubin First Look (RFL) data. Our database…
Asteroid phase curve modeling with empirical correction for shape and viewing geometry
Dagmara Oszkiewicz. PrzemysÅaw Bartczak, Milagros Colazo, Antti Penttilä
We present a novel empirical method for correcting asteroid phase curves for rotational and geometrical effects using precomputed spin-and-shape models. Our approach normalizes spa…
A catalog of near-IR absolute magnitudes of Solar System small bodies
Alvaro Alvarez-Candal, Juan Luis Rizos, Milagros Colazo +5
Context. Phase curves of small bodies are useful tools to obtain their absolute magnitudes and phase coefficients. The former relates to the object's apparent brightness, while the…
Asteroid phase curves and phase coloring effect using the ATLAS survey data
Colazo Milagros, Dagmara Oszkiewicz, Alvaro Alvarez-Candal +3
We determined phase curves for 301,272 asteroids in the orange filter and 280,953 in the cyan filter from the latest ATLAS Solar System Catalog V2 (SSCAT-2). Among them, 3,345 and…
