Indirect methods for finding exoplanets
Methods that rely on measured aspects of the star to extrapolate the existence of a planet; tells us the orbital period
Direct methods for finding exoplanets
Using photography, imaging, and spectroscopy
Dynamical Effects for finding exoplanets
Stars moving due to planets by gravitational tugs
Gravitational Lensing
A star with a planet bends background light in specific measurable ways
Weak Lensing
Only noticeable for many objects
Strong Lensing
noticeable for just one object
Macrolensing
resolved into multiple images
Microlensing
Discrete multiple images are not resolved
Caustic
An event of formally infinite magnification, used to determine the angular separation between the star and the planet
