astro[sound]bites – Détails, épisodes et analyse

This episode marks Kiersten’s last astro[sound]bites episode (and also side note – we’re posting this on her birthday!). To recognize Kiersten for her incredible time as a co-host, we take a journey through her academic paper trail by discussing her papers on how magma and metallicities affect how we think about exoplanetary formation and observations. Then we take a deep dive into Kiersten’s time as a co-host and graduate student including her stance on “publish or perish” and what she’s most excited about starting her NASA Sagan Postdoctoral Fellowship this fall.

In this week's episode, we take you on a two-part journey to Europe! First, Lucia and Cormac guide you through the differences of graduate programs in Europe and the US. Then, we jump into a series of mini-interviews with fellow PhD students about their research. We journey through a wide range of topics, including black holes big and smalls, the powerful winds of massive stars, and much more. If you would like to learn more about any of these topics, check out the links below! The mini-interviews were conducted as part of the IMPRS-Astro Hackathon, an unconference organised by Cormac and a few colleges, which brought together students from Heidelberg and Munich.

In celebration of St. Patrick’s (not Patty’s) Day, we share a super short sneak peek at next week’s episode, featuring fun Irish astronomical facts. We’re calling it the Shamrock Shake-up! In addition to the astronomical facts, Will takes us on a journey to the past with some wild Irish lore of his own! We hope you enjoy what might be our first “Beyond the beyond” episode, and Lá Fhéile Pádraig faoi mhaise daoibh go léir!

We talk about gravitational waves again, but this time, in ways you wouldn’t expect. Cormac tells us how you could use gravitational waves to study the interior of the Sun, if the alignment is just right. Sabrina explores whether gravitational waves could be detected by Earth’s magnetosphere through the Gertsenshtein effect. Simultaneously, we learn that Sabrina knows how to pronounce Russian names properly and Will isn’t the biggest fan of theory.

In the second episode of the astro[sound]bites series focusing on Indigenous astronomy, we interview Duane Hamacher, a physics professor at the University of Melbourne and a world leading researcher in Indigenous astronomy. Duane shares his journey from Missouri to pursuing a PhD in Australia and immersing himself in the study of astronomy within the Torres Strait community, learning from Indigenous knowledge holders. He tells us how Indigenous peoples around the world have seen astronomy more as a way of life that’s embedded in their culture. Through our discussion, we challenge common misconceptions and gain insight into the profound significance that Indigenous astronomy has held for humanity, long preceding the invention of telescopes. However, our interview only scratches the surface of the field of Indigenous astronomy.

Thank you to Prof. Duane Hamacher for taking the time to be interviewed for this episode! (Also sorry for the construction noise in the background of this episode! We hope the exciting interview makes up for it.)

Did you know that Indigenous communities around the world have been doing astronomy since ancient times? Indigenous peoples studied the night sky with great precision. In this episode, we talk to five indigenous astronomers from across the world to understand how their identity and communities shaped their journey to science. Their interviews tell us about their cultures from who their Elders are to how they used the constellations to harvest emu eggs. 

Thank you to Kirsten Banks, Krystal de Napoli, Hilding Nielson, Bridget Kimsey, and Corey Gray for taking the time to be interviewed for this episode!

Did we mention we’re recruiting two new co-hosts? And also our new Mars Office Manager and Chief Astrologer? Lots of exciting things are happening on a[s]b (and on Mars) in 2024 and we want you to be a part of it! Find out more and apply to be a co-host here: https://astrosoundbites.com/recruiting-2024/. We can’t wait to hear from you.

It’s all about ice, ice, baby! In this episode, Sabrina takes us on a trek to Antarctica. While we hide from Cthulhu, she tells us how the frigid observatory IceCube is using elusive neutrinos to tell us about the Milky Way. Meanwhile, our meteorologist Will does some investigation of the flavors of ice we can expect to find on some potentially habitable planets.

In this week’s episode, Cormac has somehow made it to hosting a second time (applause). This time, we discuss the smallest, reddest and exoplanetiest(?) stars - M dwarfs! Find out why we call them that, and why these temperamental ‘tars are interesting for exoplanets. Sabrina tells us about not-so-boring M stars showing complex and periodic behaviour, and Will shares some *gasp* lab work-based results showing that M dwarfs may be more habitable than we think… This week’s episode rounds off with a discussion about what the “Search for Life” really means, and how it’s (sometimes mis)used in astronomy.

This week, our astro[sound]bites co-host crew starts a dance crew with the help of Kiersten, a former professional ballerina. We get a sample of Kiersten’s ballet skills through her astrobite, which tells us all about the secret spinning life of black holes. Our space sound sounds like something only those black holes could dance to! Cormac takes us through our first ever physics education astrobite on viewing solar eclipses with a disco ball. Do not fret if our dancing analogy still did not get you to put on your tap shoes as we also discuss the importance and diversity of analogies within astronomy and the podcast.
