From Dust Bowl to Dust Bowl: Soils are Still Very Much a Frontier of Science
Soil Science Society of America Journal, Volume 75, Issue 6, Page 2037-2048, November 2011., 2011 When the Soil Science Society of America was created, 75 yr ago, the USA was suffering from major dust storms, causing the loss of enormous amounts of topsoil as well as human lives. These catastrophic events reminded public officials that soils are essential to society's well‐being. The Soil Conservation Service was founded and farmers were encouraged

NONLINEAR ASTEROSEISMOLOGY OF RR LYRAE [PDF]
The Astrophysical Journal, 2012 The observations of the Kepler space telescope revealed that fundamental-mode RR Lyrae stars may show various radial overtones. The presence of multiple radial modes may allow us to conduct nonlinear asteroseismology: comparison of mode amplitudes and frequency shifts between observations and models.

T35: A Small Automatic Telescope for Long‐Term Observing Campaigns
Advances in Astronomy, Volume 2010, Issue 1, 2010., 2010 The T35 is a small telescope (14″) equipped with a large format CCD camera installed in the Sierra Nevada Observatory (SNO) in Southern Spain. This telescope will be a useful tool for the detecting and the studying of pulsating stars, particularly, in open clusters.

Radial Oscillations in Neutron Stars from Unified Hadronic and Quarkyonic Equation of States
Galaxies, 2023 We study radial oscillations in non-rotating neutron stars by considering the unified equation of states (EoSs), which support the 2 M⊙ star criterion.

Asteroseismology with SuperWASP [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractThe highly successful SuperWASP planetary transit finding programme has surveyed a large fraction of both the northern and southern skies. There now exists in its archive over 420 billion photometric measurements for more than 31 million stars.

Astronomy & AstrophysicsContext. Solar-like oscillations have to date been observed in hundreds of main-sequence and sub-giant stars. However, only a select number of detections have been made in K-type dwarfs, using extreme-precision ground-based radial velocity observations ...

The Hot Limit of Solar-like Oscillations From Kepler Photometry
Frontiers in Astronomy and Space Sciences, 2020 Kepler short-cadence photometry of 2,347 stars with effective temperatures in the range 6,000–10,000 K was used to search for the presence of solar-like oscillations.

Recent Progress in Asteroseismology [PDF]
Symposium - International Astronomical Union, 2001 Asteroseismology, the study of stellar interiors on the basis of observations of multi-mode stellar oscillations, extends over a large part of the Hertzsprung-Russell diagram. The recently discovered EC14026 stars promise information about the properties of stars on the horizontal branch.

Asteroseismology of Compact Stars
UniverseCompact stars have been perceived as natural laboratories of matter at an extremely high density. The uncertainties of the equation of state (EOS) of matter can be constrained by observing compact stars.

An overview of helio- and asteroseismology [PDF]
Symposium - International Astronomical Union, 1988 The purpose of the present paper is to give an introduction to the nomenclature, and a few of the results, of helio- and asteroseismology. It is hoped that this may provide a useful background for the more specialized reviews, and the contributed papers, in these proceedings.
