PPT-Extrasolar Planets

Dr Jade CarterBond Lillians Daughter U3A 6 June 2012 Extrasolar Planets What they are what we know about them why we should care where ET lives just kidding what Ive been doing for the last 12 years and why your tax dollars should continue to help. For example the Doppler technique gives us information about the stars velocity toward or away from us and from this we can find its mass It is possible to calculate the planets velocity using its orbital period and distance from its star Using the This is a natural starting spot But what if planets are exceedingly rare This would put a dam per on the prospects for abundant life in the universe We therefore need information about how common planets are and the properties of their orbits and of !~2/3 - Temperature and "T Extra-solar planetary systems. Lecture . 16. Other theory. Tidal Hypothesis. Early attempt to explain the dichotomy of planets.. Problem?. tidal force strong enough to “draw out” a filament from stars will effectively disperse it before it could condense into planets!. Name: Question 2:abel thepositions on the planet’s orbit with the letters corresponding to the labeled positions of the radial velocity curve. Hint: the radial velocity in the plot is still that Extra. Solar Planets. Rahul. I. Patel. PHY 599 – Grad Seminar. Oct. 18. th. 2010. Rahul I. Patel : Extrasolar Planets. OUTLINE. Motivation.
