Detecting Exoplanetary Systems with Microlensing - Scott Gaudi (SETI Talks)
Δημοσιεύτηκε στις 24 Σεπ 2015
Measurements
of the demographics of exoplanets over a range of planet and host star
properties provide fundamental empirical constraints on theories of
planet formation and evolution. Because of its unique sensitivity to
low-mass, long-period, and free-floating planets, microlensing is an
essential complement to our arsenal of planet detection methods.
Dr.
Gaudi will review the microlensing method, and discuss results to date
from ground-based microlensing surveys. Also, Dr. Gaudi will motivate a
space-based microlensing survey with WFIRST-AFTA, which when combined
with the results from Kepler, will yield a nearly complete picture of
the demographics of planetary systems throughout the Galaxy.
