Greetings LAGS Members and Friends!

Please join us for tonight's monthly LAGS meeting (Tuesday, August
17), beginning at 7:30pm at the Christian Church in Los Alamos. We
have the pleasure of hosting Dr. Joyce Guzik as our speaker this
evening. Joyce is an astrophysicist, a Los Alamos National Laboratory
Fellow, and former president of the Los Alamos Geological Society.

Talk Title: Journey to the Center of the Sun

Abstract: Although we know more about the Sun than any other star,
only the surface is directly visible. How do we know what is going on
inside? This talk will discuss how scientists use a variety of tools,
including acoustic waves, to see beneath the Sun’s exterior, a subject
known as ‘helioseismology’. While it might be a welcome companion on a
tropical beach, the Sun is actually a turbulent volatile object,
shaken by “sun-quakes” and traversed by X-rays streaming from a hot
dense core where the equivalent of 100 billion hydrogen bombs explode
every second. Also explored will be predictions for the Sun’s future
and their implications for temperatures on Earth. The talk will close
with prospects to use oscillations observed in other stars to infer
their interior structure (astroseismology).

Hope to see you this evening! Refreshments will be served.
