Next #SETILive: Pulsing White Dwarf!
TODAY, 28 August, 11:00 am PDT

Join us for a livestream with Simon Steel and Sanne Bloot on one of the universe’s most puzzling new discoveries: a white dwarf that emits highly polarized radio pulses in a patterned rhythm. 🧪 👩‍🔬

Another great result by @astrosanne.bsky.social. She has found an new long-period transient and found it contains another white dwarf - which is doing a weird dance in the sky with another star. Hear about it all here at this snazzy video: www.youtube.com/shorts/i8Re1...

11th BCool meeting 11th BCool meetingImage: Allison LiThe 11th Bcool meeting will take place from April 9-11 2024 at ASTRON in the Netherlands, situated in the lush Dwingelderveld National Park. The aim of this meeting is to strengthen links between the worlds of stellar magnetism and radio astronomy. The scope of the meeting covers both observations and theory in topics such as:magnetic fields of stars, brown dwarfs, and planetsdynamo processesstellar winds and coronal mass ejectionsstar-planet...

Delighted to announce that the next Bcool meeting take place from April 9-11th 2024 at ASTRON! The deadline for registration and abstract submission is March 8th. Details: indico.astron.nl/e/bcool2024

The first paper of my PhD was accepted in A&A this week! We observed the young and active M dwarf AU Microscopii with the Australia Telescope Compact Array for over 250 hours and found a wide variety of radio bursts. It's up on the arXiv now! arxiv.org/abs/2312.09071
