Testing Bimodal Planet Formation
Dale L. Fields, Andrew Gould
We suggest that the observed break in giant-planet frequency as a function of host metallicity at Z=0.02 may be a reflection of bimodal planet formation. We search for signatures o…

High-Precicison Limb-Darkening Measurement of a K3 Giant Using Microlensing
Dale L. Fields, M. D. Albrow, J. An +21
We obtain high-precision limb-darkening measurements in five bands (V, V_E, I_E, I, and H) for the K3 III (Teff=4200 K, [Fe/H]=+0.3, log(g)=2.3) source of the Galactic bulge microl…
