Cosmic Savannah Ep. 74: Simulating Cosmic Nurseries

Hosted by Dr. Jacinta Delhaize, Dr. Tshiamiso Makwela & Dr.
Daniel Cunnama.


This episode of Cosmic Savannah features Professor James
Chibueze, a distinguished professor at the University of
South Africa, discussing his research on star formation using
radio astronomy.


 


During the episode, Prof Chibueze discusses his journey to become
a professional astronomer and how he got interested in radio
astronomy. Prof Chibueze also gives some insight into his
experience doing his PhD in Japan and even having to learn
Japanese. James also discusses his work on studying young
spinning stars which produce bipolar outflows.


 


To shed angular momentum, stars launch outflows of gas
perpendicular to their accretion disc, typically from the north
and south poles. Using high-resolution radio astronomy
techniques, Prof Chibueze’s research revealed that the ejected
gas in these outflows is also spinning. This finding suggests
that the outflowing gas carries away the star’s angular momentum,
allowing it to continue accreting material and grow.
