ABSTRACT
In February 2009 NASA will launch the Kepler satellite, a mission designed to discover habitable Earth-like planets around distant Sun-like stars. The method that Kepler will use to detect distant worlds will only reveal the size of the planet relative to the size of the host star, so part of the mission is devoted to characterizing distant Suns using a technique known as "asteroseismology". I have developed an automated approach to matching computer models of stars to such observations, based primarily on a parallel genetic algorithm. I will give a broad overview of how we can probe the insides of stars using seismology, and I will provide a general background on the operation of our model-fitting application. I will conclude with our first results on a nearby star: the Sun.
Speaker: Travis Metcalfe Travis Metcalfe is an astronomer at the National Center for Atmospheric Research in Boulder, Colorado. He started his career in the backyard of his childhood home in rural Oregon, and continued it in such places as Tucson, Austin, and Boston before landing in Boulder four years ago.

So glad this GoogleTechTalk on Travis Metcalfe's adventurous interdisciplinary astronomy is available. We asked Travis to talk a bit about his scientific interests and how he got started on his research career. You'll find that interview in the "People Spotlights" on UCAR's website. We've also started a new NCAR + UCAR Science channel on YouTube (ncarucar). Let us know what you think.
is that anyway to listen faster. anybody knows any program to do that. so slow .. not just that video, everybody-video run slow. i am bored. i would like to listen and watch faster.
could you please guide me? how can i run faster those videos and listen faster them...
why not exercise or do some housework while you listen?
I guess if you want to sit there and watch it's best to be in a very relaxed, slightly groggy mood. You could also download the video (google how) then play back the audio file at a higher speed with something like audacity, but you won't have the video.
i have four monitors and i can watch four different videos at once. Its supposed to be impossible to concentrate on more than one at a time, but believe me you can train yourself to do it. I'm trying to get it up to 10 but so far i got up to 6 for about 2 mins then i lost it.
Thanks for a clear introduction into asteroseismology. It brought up good memories from an astrophysics and unrelated computational seismology course course that I followed some time ago. Now I know how they are related...
Also thanks for introducing (at the end) the Pale Blue Dot project. Maybe I'll adopt a star...
