Matt Lochansky will present a talk on Stellar Spectroscopy for this month’s RAC virtual Meeting.

Abstract: Without the ability to visit distant worlds, we let the far-away light come to us. By separating this starlight into wavelengths, we can learn and about the speed, temperature, and composition of celestial objects and begin to understand the similarities and differences between them. Low resolution measurements can be taken with the same equipment required for for video astronomy with the addition of a reasonably priced filter – and it can still have scientific value. With such a setup, you can measure gases on Neptune, type supernova and transient phenomena, and explore main sequence and exotic stars like wolf-rayets, carbon, and shell stars.

We hope to see you all on line this Friday night – May 8 7:30 – 8:30PM – See the link below
