The Role of Massive Agb Stars in the Early Solar System Composition

Josep M. Trigo-Rodriguez, Domingo Anibal Garcia-Hernandez, Maria Lugaro +4

We demonstrate that a massive asymptotic giant branch (AGB) star is a good candidate as the main source of short-lived radionuclides in the early solar system. Recent identificatio…

D-instantons and twistors

Sergei Alexandrov, Boris Pioline, Frank Saueressig +1

Finding the exact, quantum corrected metric on the hypermultiplet moduli space in Type II string compactifications on Calabi-Yau threefolds is an outstanding open problem. We addre…

Effective shape and phase behaviour of short charged rods

Eelco Eggen, Marjolein Dijkstra, René van Roij

We explicitly calculate the orientation-dependent second virial coefficient of short charged rods in an electrolytic solvent, assuming the rod-rod interactions to be a pairwise sum…

A geometric approach to Conn's linearization theorem

Marius Crainic, Rui Loja Fernandes

We give a soft geometric proof of the classical result due to Conn stating that a Poisson structure is linearizable around a singular point (zero) at which the isotropy Lie algebra…

Shape Fitting on Point Sets with Probability Distributions

Maarten Loffler, Jeff M. Phillips

A typical computational geometry problem begins: Consider a set P of n points in R^d. However, many applications today work with input that is not precisely known, for example when…

The spatial distribution of star and cluster formation in M51

R. A. Scheepmaker, H. J. G. L. M. Lamers, P. Anders +1

Aims. We study the connection between spatially resolved star formation and young star clusters across the disc of M51. Methods. We combine star cluster data based on B, V, and I-b…
