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

open access: yesMonthly Notices of the Royal Astronomical Society, 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 consequently gives us the ability to detect the Moon much closer to the Sun than is the case of ...

The Calibration of the 35–40 GHz Solar Radio Spectrometer with the New Moon and a Noise Source [PDF]

open access: goldAstrophysical Journal Supplement Series, 2023
Calibrating solar radio flux has always been a concern in the solar community. Previously, fluxes were calibrated by matching load or the new Moon for relative calibration, and at times with the assistance of other stations’ data. Moreover, the frequency

A NEW CHRONOLOGY FOR THE MOON AND MERCURY [PDF]

open access: yesThe Astronomical Journal, 2009
In this paper we present a new method for dating the surface of the Moon, obtained by modeling the incoming flux of impactors and converting it into a size distribution of resulting craters. We compare the results from this model with the standard chronology for the Moon showing their similarities and discrepancies.

New Jupiter Satellites and Moon-Moon Collisions [PDF]

open access: greenResearch Notes of the AAS, 2018
We report the discovery of 12 new satellites of Jupiter, giving Jupiter 79 known satellites. The new finds are between 23rd-24th mag in the r-band and 1-3 km in diameter assuming dark albedos. Nine of the discoveries are in the distant retrograde satellite groupings.

Distributions of Conception and Parturition in Dogs According to the Lunar Phase [PDF]

open access: yesAnimals
The possible effects of the Moon and its phases on parturition timing have been extensively reported in the literature in both human and animal species, sometimes finding a causal relationship and other times denying any possible influence.

A New Disintegrative Capture Theory for the Origin of the Moon [PDF]

open access: greenarXiv, 2012
The object that resulted in the creation of the Moon started in the same orbital path as Earth around the Sun, but at Earth's L4. This proto-Moon (PM) was 4 times less massive than the usual Giant Impact (GI) object "Theia" and was captured into Earth orbit. It had a 32% Iron-Nickel-Sulfur core supporting a dynamo, which explains magnetized lunar rocks.

Are children like werewolves? Full moon and its association with sleep and activity behaviors in an international sample of children [PDF]

open access: yesFrontiers in Pediatrics, 2016
In order to verify if the full moon is associated with sleep and activity behaviors, we used a 12-country study providing 33710 24-hour accelerometer recordings of sleep and activity.

LUNA: An algorithm for generating dynamic planet-moon transits [PDF]

open access: yesMon. Not. R. Astron. Soc., 2011, Volume 416, Issue 1, pp. 689-709, 2011
It has been previously shown that moons of extrasolar planets may be detectable with the Kepler Mission, for moon masses above ~0.2 Earth masses Kipping et al. 2009c. Transit timing effects have been formerly identified as a potent tool to this end, exploiting the dynamics of the system.

Primordial Earth mantle heterogeneity caused by the Moon-forming giant impact [PDF]

open access: yes, 2019
The giant impact hypothesis for Moon formation successfully explains the dynamic properties of the Earth-Moon system but remains challenged by the similarity of isotopic fingerprints of the terrestrial and lunar mantles. Moreover, recent geochemical evidence suggests that the Earth's mantle preserves ancient (or "primordial") heterogeneity that ...
