Description
Radio Stars: now and in the future
Stars are the engines of the Universe, recycling and distributing the elements that make up all matter. Stars also critically influence the planets that orbit them; impacting their formation, atmospheric composition, and temperature. Yet, despite the diagnostic power of radio emission - which directly traces particle acceleration, magnetospheric currents and probes stellar space weather environments - fewer than 1,500 stars have been detected in the radio. Recent advances in the sensitivity, bandwidth and survey speed of radio telescopes are transforming stellar radio astronomy.
My work on the Sydney Radio Star Catalogue has more than doubled the number of known radio stars since the first version of the catalogue released in late 2024. I will talk about the reinvigoration of the field of stellar radio astronomy and discuss some of the key science questions I am addressing using the powerful ASKAP telescope. This includes stellar flares, space weather, and exoplanet habitability and magnetic fields.
I will share my latest work on the Sydney Radio Star Catalogue and also look forward to the future of stellar radio astronomy with upcoming radio instruments.
