Combining asteroid models derived by lightcurve inversion with asteroidal occultation silhouettes [PDF]

open access: yes, 2011
Asteroid sizes can be directly measured by observing occultations of stars by asteroids. When there are enough observations across the path of the shadow, the asteroid's projected silhouette can be reconstructed. Asteroid shape models derived from photometry by the lightcurve inversion method enable us to predict the orientation of an asteroid for the ...

Asteroid taxonomic signatures from photometric phase curves [PDF]

open access: yes, 2012
We explore the correlation between an asteroid's taxonomy and photometric phase curve using the H, G12 photometric phase function, with the shape of the phase function described by the single parameter G12. We explore the usability of G12 in taxonomic classification for individual objects, asteroid families, and dynamical groups.

Origin of asteroid (101955) Bennu and its connection to the New Polana family [PDF]

open access: yesScientific Reports
The asteroid (142) Polana is classified as a B-type asteroid located in the inner Main Belt. This asteroid is the parent of the New Polana family, which has been proposed to be the likely source of primitive near-Earth asteroids such as the B-type ...

MONET: The Minor Body Generator Tool at DART Lab [PDF]

open access: yesSensors
Minor bodies exhibit considerable variability in shape and surface morphology, posing challenges for spacecraft operations, which are further compounded by highly non-linear dynamics and limited communication windows with Earth.

Soluble organic molecules in samples of the carbonaceous asteroid (162173) Ryugu

open access: yesScience, 2023
The Hayabusa2 spacecraft collected samples from the surface of the carbonaceous near-Earth asteroid (162173) Ryugu and brought them to Earth. The samples were expected to contain organic molecules, which record processes that occurred in the early Solar ...

The Formation of a Rubble Pile Asteroid: Insights from the Asteroid Ryugu

open access: yesUniverse, 2023
The Hayabusa2 mission returned primitive samples from the C-type asteroid Ryugu to Earth. The C-type asteroids hold clues to the origin of Earth’s water and the building blocks of life.

Samples returned from the asteroid Ryugu are similar to Ivuna-type carbonaceous meteorites

open access: yesScience, 2022
Carbonaceous meteorites are thought to be fragments of C-type (carbonaceous) asteroids. Samples of the C-type asteroid (162173) Ryugu were retrieved by the Hayabusa2 spacecraft.

Formation and evolution of carbonaceous asteroid Ryugu: Direct evidence from returned samples

open access: yesScience, 2022
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters.
