Stellar flybies within 1 ly from the Sun and stars passing through the Hills cloud
Igor Yu. Potemine
We reexamine the SIMBAD database with incorporated Gaia DR3 parallaxes and proper motions. Appropriate query searches allow us to find several nearby stars with measured radial vel…
Hyperverse, 5-dimensional gravity and multiverses as nested Gogberashvili shells
Igor Yu. Potemine
We consider the Hyperverse as a collection of multiverses in 5-dimensional spacetime with gravitational constant . Each multiverse in our simplified model is a bouquet of nested…
Amalgamated Geometric Structure of the Local Multiverse
Igor Yu. Potemine
We consider multiverses as time-amalgamated multiply warped products of Lorentzian (Einstein) manifolds. We define the Local Multiverse as timely-connected component of our physica…
Hecke-Langlands Duality and Witten's Gravitational Moonshine
Igor Yu. Potemine
We show that there is a dual description of conformal blocks of rational CFT in terms of Hecke eigenfields and eigensheaves. In particular, partition functions, conformal cha…
Nemesis encounters of nearby Hipparcos stars
Igor Yu. Potemine
Very close encounters of stars might lead to significant perturbations of their Oort-type clouds, planetesimal belts and planetary systems. We have calculated encounter parameters…
Transit of Luyten 726-8 within 1 ly from Epsilon Eridani
Igor Yu. Potemine
This is one of results from our program of massive simulations of close encounters for all nearby stars. Epsilon Eridani is an extremely interesting star having one confirmed plane…
