The Ni isotopic composition of Ryugu reveals a common accretion region for carbonaceous chondrites
Fridolin Spitzer, Thorsten Kleine, Christoph Burkhardt +88
The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the sugge…
Electronic interactions of a new quatertiophene-based surfactants atliquid/gas interface
Changwoo Bae, Kamatham Narayanaswamy, Hisham Idriss +7
We report the synthesis of a new functional molecule, a quater-tiophene based surfactant, which can both adsorb at the water / gas interface (surface active molecule) and aggregate…
Hyperseries subfields of surreal numbers
Vincent Bagayoko
We study subfields of surreal numbers, called hyperseries fields, that are suited to be equipped with derivations and composition laws. We show how to define embeddings on hyperser…
An Extremely Elongated Cloud over Arsia Mons Volcano on Mars: II. Mesoscale modeling
Jorge From, :, Jorge Hernández-Bernal +5
In a previous work (Hernández-Bernal et al. 2021) we performed an observational analysis of the Arsia Mons Elongated Cloud (AMEC), which stands out due to its impressive size and s…
The Visual Monitoring Camera (VMC) on Mars Express: a new science instrument made from an old webcam orbiting Mars
Jorge From, :, Jorge Hernández-Bernal +19
The Visual Monitoring Camera (VMC) is a small imaging instrument onboard Mars Express with a field of view of ~40x30 degrees. The camera was initially intended to provide visual co…
Répartition conjointe de trois nombres premiers et applications
Régis de la Bretèche
We prove asymptotic results for the singular series associated to the distribution of three primes. Assuming a quantitative version of Hardy and Littlewood's conjecture on prime 3-…
