Long-Term Citation Histories of Astronomical Papers
Publications of the Astronomical Society of the Pacific, 1981We studied the citation histories of 326 papers published in 1961 and cited in the 18 subsequent years. On the average the citations reached a maximum five years after publication, followed by a slow decline such that 20 years after publication the citation rate is half the maximum rate. Theoretical papers show the same rate of decline as observational

GpDL: A Spatially Aggregated Data Layout for Long-Term Astronomical Observation Archive
2018A great number of excellent astronomical academic achievements are built on historical observation data. So long-term astronomical observation archive has great significance for astronomical research. At the observation site, data from different sky areas shot in a consecutive time period are stored in one disk.

Long-term Statistics of Meteorological Data at the Maidanak Astronomical Observatory
Research in Astronomy and AstrophysicsAbstract We present a comprehensive analysis of meteorological parameters measured at the Maidanak Astronomical Observatory over the period 2013–2024, aimed at characterizing the site for the planned installation of a new 4 m telescope. The study includes annual and monthly statistics of key variables such as wind speed and direction,

A long-term geophysical and astronomical dataset: sunspot counting from 1610 to 2021
2021<p>Solar activity is an essential factor for the study of many aspects of the geophysical and astronomical sciences. A very simple measure of solar activity is counting sunspots using telescopes. This task can be done even with small telescopes since the Sun is apparently a very large and luminous star.

Stability of the long period terms in the La2011 astronomical solution.
2012The obtention of an accurate astronomical solution for the orbital motion of the Earth in the Solar System is an essential step for the elaboration of geological time scales that are based on the correlation of sedimentary cycles with insolation variations on the Earth's surface.

The history of solar observations in the radio range at the Mountain Astronomical Station, State Astronomical Observatory, Russian Academy of Sciences (MAS RAS) since 1957 is outlined. The stages of the formation and development of radio observations are described, from the creation of a radio interferometer of the meter wavelength range to modern ...

Geomagnetism and Aeronomy, 2011
We analyzed the variations of the interplanetary plasma parameters, obtained from radio astronomical observations of scintillations of cosmic radio sources during four 11-year cycles of solar activity, from 1966 to present. It is shown that the state of the interplanetary plasma permanently changes in conformity with cyclicity in the solar activity. In

Understanding rapid climate variations during the Late Ordovician in terms of astronomical forcing.
2015Cyclostratigraphy comprises the study of astronomically forced climate cycles as expressed in the sedimentary record. Such studies are particularly challenging when applied to the deep geological time. Recent studies (De Vleeschouwer & Parnell, 2014) however, have now successfully demonstrated the astronomical rhythm of climate changes as far as the ...
