2. 26 June 2007David Barnaby, WKU2 Direction Physics & Astronomy Grand Prize Winner Cataclysmic Variables Judging Process –Other great projects I voted for –Insights Top ISEF Winners

3. 26 June 2007David Barnaby, WKU3 Physics & Astronomy Grand Prize

4. 26 June 2007David Barnaby, WKU4 Cataclysmic Variables Roche Lobe Overflow

5. 26 June 2007David Barnaby, WKU5 Cataclysmic Variable Light Curve Low state: accretion Flares: thermonuclear runaway on white dwarf surface. Subclasses –Novae –Dwarf Novae

6. 26 June 2007David Barnaby, WKU6 Dwarf Novae Classifications Arranged by magnetic activity. –None magnetic: dwarf novae –Intermediate polars: DQ Her, 10 MegaGauss –Polars: AM Her, 100 MegaGauss

7. 26 June 2007David Barnaby, WKU7 Intermediate Polars: DQ Her WD: relatively strong magnetic field –Plasma dragged away from inner disk –Channeled to and crashes into magnetic poles. –Can produce hard X-rays.

8. 26 June 2007David Barnaby, WKU8 Polars: AM Her WD: extremely strong magnetic field –Prevents accretion disk. –Plasma crashes preferentially into magnetic pole. Consequences –Strong source of soft & hard x-rays –Rotation introduces variation in soft x-rays –WD magnetically locked to companion

9. 26 June 2007David Barnaby, WKU9 Question: why does X-ray emission decrease during low states?

10. 26 June 2007David Barnaby, WKU10 The Judging Process 1510 Contestants 17 Panels 1200 Judges Physics & Astronomy –86 judges –Affiliations

11. 26 June 2007David Barnaby, WKU11 The First Day Schedule, Schedule, Schedule! Pep talk from software designer. –Decision making with partial information. –Most will not have interviewed the winner! Look over all 86 entries –Including team entries.

12. 26 June 2007David Barnaby, WKU12 Some of the 20 Astronomy Projects Variation on the Star Formation Rate from Galaxy Cluster Center c11037 Simulations of Gravitational  lensing Events Involving Nearby Lenses and Effects of Parallax Mars Rover: Could It Be Better? Determining Surface Composition of KBOs Through Spectrum Matching Heating the Rings: The Thermodynamics of the Rings of Saturn

13. 26 June 2007David Barnaby, WKU13 The Second Day 10 interviews assigned –15 minute blocks –Scantron cards. Back in caucus room –Straw poll of early favorites. Distinguishing elements of my approach –Questions. –Form 1C.

14. 26 June 2007David Barnaby, WKU14 Early Favorites and Extra Interviews Cosmic Rain Ball Lightning Leidenfrost Effect Kuiper Belt Objects

15. 26 June 2007David Barnaby, WKU15 Now, for the Caucus! Process for selecting –3 1st place –4 2nd place –5 3rd place –6 4th place Co-chairs, blow-hards, and curmudgeons. –My ranking –Mr Temple won: solved long-standing problem; 2 papers “in press” Wrapped up with 5 minutes to spare!

16. 26 June 2007David Barnaby, WKU16 My Insights Get abstracts of all 1st and 2nd place winners! Helps to have a well-endowed mentor. –Data, ideas, money, equipment. –Mentor contribution did NOT appear factor. Publications, even rumored, help a lot! Depth of understanding equally important. –How does this fit into a larger picture? –An intriguing solution to a problem?
