Meter- to Millimeter Emission from Cool Stellar Systems: A Cool Stars 20 Splinter Session

Meter- to Millimeter Emission from Cool Stellar Systems:

Latest Results, Synergies Across the Spectrum, and Outlook for the Next Decade

Lead organizers: Jan Forbrich (Hertfordshire), Peter K. G. Williams (Harvard CfA). Co-organizers: Edo Berger (Harvard CfA), Manual Güdel (Vienna), Rachel Osten (STScI).


A splinter session of the Cool Stars 20 conference, held July 29–August 3, 2018 in Boston, USA.

Radio observations of cool stellar systems provide unique information on their magnetic fields, high-energy processes, and chemistry. Buoyed by powerful new instruments (e.g. ALMA, JVLA, LOFAR), advances in related fields (e.g. the Gaia astrometric revolution), and above all a renewed interest in the relevant stellar astrophysics, stellar radio astronomy is experiencing a renaissance. In this splinter session, participants will take stock of the present state of stellar radio astronomy and chart a course for the field’s future. Read more on the Motivation page.

Urgent! Submit a poster pop slide!

The session will include a “poster pop” segment, where you can have 60 seconds and one slide to advertise your poster. If you’d like to participate, email your slide as a one-page PDF to before Tuesday afternoon!

Submit soon as slots are limited. Submissions connecting to the session theme will be preferred, but all topics are welcome.

The location of the splinter will be the “auditorium” room.

It’s located behind the main room in which the plenaries take place.

Can’t get enough? Join us for a “radio dinner”

We’re exploring the idea of a “radio dinner” on Tuesday night after the splinter session. If you’re interested, please contact Let us know if you have any food allergies, and (for scheduling purposes) if you’d also like to attend the “Academics to Industry” panel of Tuesday evening.

The session will take place Tuesday afternoon (July 31). The location will be determined day-of based on needed room capacity.
