Investigation of the dynamics and origin of the NEA pair 2021 PH27 and 2025 GN1

Albino Carbognani, Marco Fenucci, Toni Santana-Ros +2

We analyse the association between the NEAs 2021 PH27 and 2025 GN1, which share similar heliocentric Keplerian elements and the same taxonomic classification. First, we confirm the…

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…
