Debiasing astro-Photometric Observations with Corrections Using Statistics (DePhOCUS)
Tobias Hoffmann, Marco Micheli, Juan Luis Cano +5
Photometric measurements allow the determination of an asteroid's absolute magnitude, which often represents the sole means to infer its size. Photometric observations can be obtai…
An Earth Encounter As the Cause of Chaotic Dynamics in Binary Asteroid (35107) 1991VH
Alex J Meyer, Oscar Fuentes-Muñoz, Ioannis Gkolias +4
Among binary asteroids, (35107) 1991VH stands out as unique given the likely chaotic rotation within its secondary component. The source of this excited dynamical state is unknown.…
The Yarkovsky effect on the long-term evolution of binary asteroids
Wen-Han Zhou, David Vokrouhlicky, Masanori Kanamaru +4
We explore the Yarkovsky effect on small binary asteroids. While significant attention has been given to the binary YORP effect, the Yarkovsky effect is often overlooked. We develo…
