TL;DR: The detection of a cool, sub-Neptune-mass planets may be more common than gas giant planets, as predicted by the core accretion theory, and is suggested to name OGLE-2005-BLG-390Lb, indicating a planetary mass companion to the lens star of the microlensing event.

TL;DR: In this paper, the mass function and statistics of very low-mass stars were measured from the combined measurements of the Einstein radius and microlens parallax, and the masses of the binary components were measured.

TL;DR: In this paper , the authors estimate the neutral fraction, x HI, from the observed number density ratio of LAEs to LBGs, n(LAE)/n(LBG), using numerical radiative transfer simulations, in which model galaxies are selected to satisfy the observed selection function.
