Is the Growth of the Astronomical Unit Caused by the Allais Eclipse Effect?
《Journal of Modern Physics》2023年第2期127-146,共20页Russell Bagdoo 
In addition to the Pioneer anomaly and the Earth flyby anomaly for spacecraft, other unexplained anomalies disrupt the solar system dynamics, like the astronomical unit. We show in this paper that the Allais eclipse e...

Successful Detection of a Preferred Frame Using Eclipses of Jupiter’s Moon Io
《Journal of Applied Mathematics and Physics》2022年第2期322-332,共11页Stephan J. G. Gift 
In this paper tests by Maxwell and Gift that search for a preferred frame or ether arising from movement through that frame using Jupiter’s moon Io are reviewed and discussed. Unlike the Michelson-Morley second-order...

Candidates of eclipsing multiples based on extraneous eclipses on binary light curves: KIC 7622486, KIC 7668648, KIC 7670485 and KIC 8938628
《Research in Astronomy and Astrophysics》2017年第3期1-12,共12页Jia Zhang Sheng-Bang Qian Jian-Duo He 
partly supported by the West Light Foundation of the Chinese Academy of Sciences, Yunnan Natural Science Foundation (Y5XB071001);the National Natural Science Foundation of China (Grant Nos. 11133007 and 11325315);the Key Research Program of the Chinese Academy of Sciences (Grant No. KGZD-EW-603);the Science Foundation of Yunnan Province (No. 2012HC011);by the Strategic Priority Research Program “The Emergence of Cosmological Structures” of the Chinese Academy of Sciences (No. XDB09010202)
Four candidates of eclipsing multiples, based on new extraneous eclipses found on Kepler binary light curves, are presented and studied. KIC 7622486 is a double eclipsing binary candidate with orbital periods of 2.279...

Statistical analysis of geomagnetic field variations during the partial solar eclipse on 2011 January 4 in Turkey
《Research in Astronomy and Astrophysics》2015年第5期742-752,共11页Abdullah Ates Yunus Levent Ekinci Aydin Buyuksarac Attila Aydemir Alper Demirci 
Some geophysical parameters, such as those related to gravitation and the geomagnetic field, could change during solar eclipses. In order to observe geomagnetic fluctuations, geomagnetic measurements were carded out i...

The Torsind—A Device Based on a New Principle for Non-Conventional Astronomical Observations
《International Journal of Astronomy and Astrophysics》2013年第2期33-38,共6页Alexander F. Pugach 
The description of a new device which is an improved version of the classic torsion balance is given. The device, which is the so-called “torsind”, seemed to be very sensitive to solar/lunar eclipses, and a Venus tr...

Guidelines for measuring solar radius with Baily beads analysis被引量:2
《Science China(Physics,Mechanics & Astronomy)》2009年第11期1773-1777,共5页SIGISMONDI Costantino 
By inspection of central eclipses videorecords, data of Baily beads timings are retrievable. Knowing the lunar limb profile at the moment of the eclipse we evaluate the excess or defect of solar limb when the Sun is a...
