Infrared-to-visible albedo ratio of Phobos: Comparison with primitive asteroids
T. J. Dyer, J. Beccarelli, M. Delbo +5
Aims. The ratio between infrared and visible albedo, pIR/pV, provides a simple proxy for the spectral slope of asteroid surfaces between the visible and near-infrared wavelength ra…
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…
The dependence of the asteroid rotation on their composition
T. J. Dyer, W. -H. Zhou, C. Avdellidou +4
The rotational properties of asteroids provide critical information about not only their internal structure but also their collisional and thermal histories. Previous work has reve…
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…
