EVIDENCE FOR A DISTANT GIANT PLANET IN THE SOLAR SYSTEM [PDF]
, 2016 Recent analyses have shown that distant orbits within the scattered disk population of the Kuiper Belt exhibit an unexpected clustering in their respective arguments of perihelion. While several hypotheses have been put forward to explain this alignment,

Spectral analysis for wide energy channels [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2013 For energetic particle measurements whose spectra follow a power law, it is often challenging to define a characteristic ("effective") energy of an energy channel.

Was Venus the first habitable world of our solar system? [PDF]
Geophysical Research Letters, 2016 Present‐day Venus is an inhospitable place with surface temperatures approaching 750 K and an atmosphere 90 times as thick as Earth's. Billions of years ago the picture may have been very different.

Mapping Solar System chaos with the Geological Orrery
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance The Solar System is chaotic, and precise solutions for the motions of the planets are limited to about 60 million years. Using a network of coring experiments that we call the Geological Orrery (after 18th century planetaria), we recover ...

Proterozoic Milankovitch cycles and the history of the solar system
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Periodic variations in Earth’s orbit and rotation axis occur over tens of thousands of years, producing rhythmic climate changes known as Milankovitch cycles.

Computation of irradiance in a solar still by using a refined algorithm [PDF]
, 2013 A refined solar algorithm from the ESP-r system has been used to calculate the distribution of solar irradiation inside a basin-type solar still. In the approach, surface finish, view factors and multiple reflections are taken into consideration in the ...

VHF radar measurements of momentum flux using summer polar mesopause echoes
Earth, Planets and Space, 2018 We revisit previously unpublished analysis of observations of the dynamics of the mesopause region over the Norwegian Island of Andøya (69°N, 16°E) made during a 1-week period in summer 1987 during the Middle Atmosphere Cooperation-Summer in Northern ...
