51 Pegasi: The First Exoplanet Discovery

This podcast is on a scientific article from Nature, reports the discovery of a Jupiter-mass exoplanet orbiting the star 51 Pegasi, detected through observations of the star's radial velocity variations. The researchers discuss the planet's orbital characteristics and consider alternative explanations for the observed data, ultimately concluding a planetary companion is the most plausible explanation. The second source details a study on an unusually strong intramolecular magnetic coupling in a chromium hydride cluster, utilising high-pressure techniques and spectroscopic analysis to characterise the molecule's magnetic properties.

Outdated, but interesting. Audio quality is very good.
