Water abundance at the surface of C-complex main-belt asteroids
Pierre Beck, Jolantha Eschrig, Sandra Potin +4
Recently published space-based observations of main-belt asteroids with the AKARI telescope provide a full description of the 3 μm band, related to the presence of OH bearing miner…
Spectral reflectance analysis of type 3 carbonaceous chondrites and search for their asteroidal parent bodies
Jolantha Escrig, Lydie Bonal, Pierre Beck +1
Non-differentiated asteroids are among the most primitive objects in our Solar System, having escaped intense heating mechanisms. To help us understand the information contained in…
Mineralogy, chemistry and composition of organic compounds in the fresh carbonaceous chondrite Mukundpura: CM1 or CM2?
S. Potin, P. Beck, L. Bonal +7
We present here several laboratory analyses performed on the freshly fallen Mukundpura CM chondrite. Results of infrared transmission spectroscopy, thermogravimetry analysis and re…
The iron record of asteroidal processes in carbonaceous chondrites
A. Garenne, P. Beck, G. Montes-Hernandez +4
The valence of iron has been used in terrestrial studies to trace the hydrolysis of primary silicate rocks. Here, we use a similar approach to characterize the secondary processes,…
Style and intensity of hydration among C-complex asteroids: a comparison to dessicated carbonaceous chondrites
S. Potin, P. Beck, F. Usui +3
Here we report a comparison between reflectance spectroscopy of meteorites under asteroidal environment (high vacuum and temperature) and Main Belt and Near Earth Asteroids spectra…
Ammonium salts are a reservoir of nitrogen on a cometary nucleus and possibly on some asteroids
O. Poch, I. Istiqomah, E. Quirico +29
The measured nitrogen-to-carbon ratio in comets is lower than for the Sun, a discrepancy which could be alleviated if there is an unknown reservoir of nitrogen in comets. The nucle…
