Impact of Metals on (Star)Dust Chemistry: A Laboratory Astrophysics Approach [PDF]
Frontiers in Astronomy and Space Sciences, 2021 Laboratory experiments are essential in exploring the mechanisms involved in stardust formation. One key question is how a metal is incorporated into dust for an environment rich in elements involved in stardust formation (C, H, O, Si).

Laboratory astrophysics: Investigation of planetary and astrophysical maser emission [PDF]
Space Science Reviews, 2013 This paper describes a model for cyclotron maser emission applicable to planetary auroral radio emission, the stars UV Ceti and CU Virginus, blazar jets and astrophysical shocks. These emissions may be attributed to energetic electrons moving into convergent magnetic fields that are typically found in association with dipole like planetary ...

Laboratory Astrophysics in Korea
, 2022 Laboratory astrophysics is still in its early stages in Korea. Yet, facilities with the potential for laboratory astrophysics have been constructed or are under construction. I will introduce three of them, high-intensity lasers at CoReLS (Center for Relativistic Laser Science), XFEL (X-ray Free Electron Laser) at PAL (Pohang Accelerator Laboratory ...

Laboratory Astrophysics: Lessons for Epistemology of Astrophysics
Synthese Library, 2023 AbstractAstrophysics is often cast as an observational science, devoid of traditional experiments, along with astronomy and cosmology. Yet, a thriving field of experimental research exists called laboratory astrophysics. How should we make sense of this apparent tension?

A Laboratory Astrophysics Problem: The Lifetime of Very Long-Lived Levels in Low-Charge Ions
Atoms, 2020 Emission lines of singly charged ions populate many astrophysical spectra. However, the interpretation of the line intensities (usually line ratios) often depends on the transition rates of the decays of very long-lived low-lying levels. For example, the

Laboratory astrophysics: Key to understanding the Universe [PDF]
Proceedings of the International Astronomical Union, 2019 AbstractThis brief overview stresses the importance of laboratory data and theory in analyzing astronomical observations and understanding the physical and chemical processes that drive the astrophysical phenomena in our Universe. This includes basic atomic and molecular data such as spectroscopy and collisional rate coefficients, but also an improved ...
