December 2019 Extra: Snow White and the Seven Dwarf Novae

December 2019 Extra

In the show this time, we talk to Simon Johnston about Searching for pulsars, Laura Driessen tells us about the first new transient source discovered with the MeerKAT telescope, a flaring stellar sys in this month's JodBite, and your astronomy questions are answered by Iain Mcdonald in Ask an Astronomer.

JodBite with Laura Driessen

Tiaan talks to Laura Driessen about the first new transient source discovered with the MeerKAT telescope, a flaring stellar system. Searching for transients in the radio is challenging, and looking for stellar flares is even more so. Laura talks about her recent paper and has also written an article on The Conversation for a more general science audience on this.

Interview with Simon Johnston

Simon Johnston talks about pulsars and their irregularities, particularly in the timing of pulsars. He discusses his work using the Parkes radio telescope in Australia to sample pulsars and what information can be gained from using these samples, before briefly explaining the possible use of MEERKAT to get a larger sample size. He then discusses his history at Manchester, where he did his PhD, and finishes by mentioning Gamma ray pulsars and the link between the radio work he has been doing and space based missions searching for gamma ray emitting objects.
