Elucidating the Formation of Ethynylbutatrienylidene (HCCCHCCC; X1A′) in the Taurus Molecular Cloud (TMC-1) via the Gas-phase Reaction of Tricarbon (C3) with the Propargyl Radical (C3H3)

The Astrophysical Journal Letters, 2023
The recent astronomical detection of ethynylbutatrienylidene (HCCCHCCC)—a high-energy isomer of triacetylene (HCCCCCCH) and hexapentaenylidene (H _2 CCCCCC)—in TMC-1 puzzled the laboratory astrophysics community since proposed reaction pathways could not

Connecting astrophysics to laboratory fluid dynamics - Astrophysical thermonuclear flashes

30th Fluid Dynamics Conference, 1999
We discuss the strategy followed by the Center for Astrophysical Thermonuclear Flashes in validating codes designed for thermonuclear burning on the surfaces or the interior of evolved compact stars. As an illustration, we discuss in some detail our progress in simulating Rayleigh-Taylor mixing relevant to Type la supernovae. © 1999 by The Univ.

Fundamental Physics and Relativistic Laboratory Astrophysics with Extreme Power Lasers

, 2012
The prospects of using extreme relativistic laser-matter interactions for laboratory astrophysics are discussed. Laser-driven process simulation of matter dynamics at ultra-high energy density is proposed for the studies of astrophysical compact objects ...

The Wisconsin Plasma Astrophysics Laboratory

, 2015
The Wisconsin Plasma Astrophysics Laboratory (WiPAL) is a flexible user facility designed to study a range of astrophysically relevant plasma processes as well as novel geometries that mimic astrophysical systems. A multi-cusp magnetic bucket constructed

Magnetic field generation and diffusion by a laser-produced blast wave propagating in non-homogenous plasma

New Journal of Physics, 2015
In this paper we discuss the magnetic field self generation, via the so-called Biermann battery effect, and its diffusion for a blast wave (BW) expanding in a perturbed background medium.

Double to Tenfold M-shell Photoionization of Singly Charged Lanthanum Ions

The Astrophysical Journal
Using the photon-ion merged-beams technique at the PETRA III synchrotron light source, we have measured cross sections for double and up to tenfold photoionization of La ^+ ions by a single photon in the energy range 820–1400 eV, where resonances and ...

Detectors and Shieldings: Past and Future at LUNA

Universe
Nuclear reactions are responsible for the chemical evolution of stars, galaxies and the Universe. Unfortunately, at temperatures of interest for nuclear astrophysics, the cross-sections of the thermonuclear reactions are in the pico- femto-barn range and

Advances in instrumentation for nuclear astrophysics

AIP Advances, 2014
The study of the nuclear physics properties which govern energy generation and nucleosynthesis in the astrophysical phenomena we observe in the universe is crucial to understanding how these objects behave and how the chemical history of the universe ...
