Enantioselective Synthesis of a New Class of Stable and Functionalized Cyclopentadienes via CuH‐Catalysis

open access: yesAngewandte Chemie, EarlyView.
Cyclopentadienes (CpHs) are fundamental building blocks with widespread applications in chemistry. However, their inherent acidity and isomeric instability have long limited access to chiral variants in an asymmetric fashion. Here, we introduce a CuH‐catalyzed asymmetric transformation that provides an unprecedented entry into a new class of ...

On the Capture of Interstellar Objects by Our Solar System

open access: yesThe Planetary Science Journal, 2021
Abstract Motivated by recent visits from interstellar comets, along with continuing discoveries of minor bodies in orbit of the Sun, this paper studies the capture of objects on initially hyperbolic orbits by our solar system. Using an ensemble of ∼500 million numerical experiments, this work generalizes previous treatments by ...

Localizing the First Interstellar Meteor with Seismometer Data

open access: yesSignals, 2023
The first meter-scale interstellar meteor (IM1) was detected by US government sensors in 2014, identified as an interstellar object candidate in 2019, and confirmed by the Department of Defense (DoD) in 2022.

A kinematical age for the interstellar object 1I/’Oumuamua [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
1I/'Oumuamua is the first interstellar object observed passing through the Solar System. Understanding the nature of these objects will provide crucial information about the formation and evolution of planetary systems, and the chemodynamical evolution of the Galaxy as a whole.

The interaction of the supermassive object R136a with the interstellar environment [PDF]

open access: yesSymposium - International Astronomical Union, 1984
R136a is the luminous object in the core of the 30 Dor nebula in the LMC, embedded in the extremely young star cluster NGC 2070 with the most recent star forming event less 106 yr ago. R136a-1 (V = 11.08) lies in the center of this cluster. The companion or foreground star R136a-2 (ca.
