Tony Zhao 2015

Exo- outside, outer, out of Ayyo wut’s an exoplanet

Ayyo why should I care ‘bout ‘em

Direct imaging Radial velocity Astrometry Microlensing Ayyo so how we gonna’ find dem’ Transit

Ayyo so how dat transit method work tho’ As the planet crosses the star, a dip in brightness can be observed

Main goal: Extrapolate the radius of the planet. Ayyo, wut chu’ tryna’ do tho’ Other goal: Determine other properties of star and planet and how they affect the curve

Meet TrES-3B

Ayyo, how dat work tho’

Where cho’ data at

How chu’ calculate radius tho’ Fraction of light blocked =

More forms of data and stuff

After calculations. Radius = TrES-3b

Important variables Radius of planet Radius of Star Mass of Star Semi-major Axis System Inclination Dem’ Secondary Objectives

Transit method works to determine the radius of the planet From that, a great deal of other properties can be inferred. Dat Conclusion tho’
