Dark asteroids exhibiting intermediate characteristics between C and X types
Sunao Hasegawa, Chrysa Avdellidou, Michael Marsset +8
Large main-belt asteroids with visible geometric albedos below 0.1 are predominantly classified within the C- and X-complex spectroscopic classes. C-type and dark X-type asteroids…
Gaia DR3 supervised classification of asteroid reflectance spectra
Marco Delbo, Thomas Dyer, Ullas Bhat +3
We present a supervised, probabilistic taxonomic classification of asteroid reflectance spectra from Gaia Data Release 3 (DR3). Using high-quality Gaia DR3 spectra and a reference…
Searching for primitive, dark, spectrally red asteroid families in the main belt with Gaia
Ullas Bhat, Chrysa Avdellidou, Marco Delbo +1
Dark asteroids with featureless neutral to red spectra are of particular interest due to their ability to potentially harbour primitive, hydrated, and possibly organic-rich materia…
Gaia and IRTF abundance of A-type main belt asteroids
Marco Delbo, Chrysa Avdellidou, Marjorie Galinier +4
The Missing Mantle Problem refers to the apparent scarcity of olivine rich (A-type) asteroids in the main belt, despite expectations that such bodies should be common if differenti…
