A Radio Determination of the Time of the New Moon [PDF]

open access: yes, 2013
The detection of the New Moon at sunset is of importance to communities based on the lunar calendar. This is traditionally undertaken with visual observations. We propose a radio method which allows a higher visibility of the Moon relative to the Sun and

Dynamics of solar wind protons reflected by the Moon [PDF]

open access: yes, 2010
Solar system bodies that lack a significant atmosphere and significant internal magnetic fields, such as the Moon and asteroids, have been considered as passive absorbers of the solar wind. However, ion observations near the Moon by the SELENE spacecraft

Maximal increasing sequences in fillings of almost-moon polyominoes [PDF]

open access: yes, 2014
It was proved by Rubey that the number of fillings with zeros and ones of a given moon polyomino that do not contain a northeast chain of size $k$ depends only on the set of columns of the polyomino, but not the shape of the polyomino.
