Nov 12, 2025 David Conine, a radio astronomer at ASTRON, shares groundbreaking insights on detecting a coronal mass ejection from a distant star, highlighting its implications for exoplanet habitability. Ditte Demontis, a geneticist, discusses her research identifying rare gene variants linked to ADHD, shedding light on neurotransmitter mechanisms. The conversation also touches on the potential of CMEs to affect planetary atmospheres and the role of genetics in understanding ADHD, offering a fascinating look at the intersection of astronomy and neurodevelopment.

Episode notes
A Bright Minute-Long Burst
- The team found a minute-long burst about 20–30 times brighter than background noise with a clear high-to-low frequency sweep.
- They confirmed the signal originated from the M-dwarf STKM1-1262 and matched expected CME drift behavior.
CMEs Affect Exoplanet Habitability
- Stellar CMEs can strip or ionize exoplanet atmospheres, especially when stronger than Earth's Carrington event.
- Observing CMEs from other stars refines habitability estimates by adding real stellar activity data beyond solar scaling.
Use Multiwavelength Observations To Confirm CMEs
- Combine simultaneous optical and radio observations to distinguish CME radio emission from other mechanisms like the electron cyclotron maser.
- Prioritize coordinated multiwavelength campaigns to confirm stellar CMEs and link radio drifts to optical flares.
