From Dust Bowl to Dust Bowl: Soils are Still Very Much a Frontier of Science

open access: yesSoil 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

T35: A Small Automatic Telescope for Long‐Term Observing Campaigns

open access: yesAdvances 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.

Asteroseismology with SuperWASP [PDF]

open access: yesProceedings 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.

Asteroseismology [PDF]

open access: yes, 2013
Our understanding of stars has grown significantly due to recent advances in asteroseismology, the stellar analog of helioseismology, the study of the Sun's acoustic wave oscillations. Using ground-based and satellite observatories to measure the frequency spectra of starlight, researchers are able to probe beneath a star's surface and map its interior

Ensemble asteroseismology

open access: yesAstronomy & Astrophysics
Context. 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 ...

Looking into dark matter with asteroseismology

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Dark matter remains as an elusive component of modern Cosmology. According to previous research, stellar physics observables can be affected by the presence of hypothetical dark matter particles, which can be produced or accreted into the stars.

Constraining stellar tidal quality factors from planet‐induced stellar spin‐up

open access: yesAstronomische Nachrichten, Volume 345, Issue 5, June 2024.
Abstract The dynamical evolution of tight star‐planet systems is influenced by tidal interactions between the star and the planet, as was shown recently. The rate at which spins and orbits in such a system evolve depends on the stellar and planetary tidal dissipation efficiency. Here, we present a method to constrain the modified tidal quality factor Q*

Seismic Cartography of White-Dwarf Interiors From the Toulouse-Montréal Optimal-Design Approach

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Probing internal properties of white-dwarf stars has been amongst the earliest objectives of asteroseismology, following the first discovery in the late 1960s of non-radial pulsations in these evolved compact stars.

Recent Progress in Asteroseismology [PDF]

open access: yesSymposium - 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.
