Ensemble Asteroseismology with the TRILEGAL and the PARAM codes An estimate of the systematic errors introduced by stellar models [PDF]
, 2022 Asteroseismology has provided precise methods for stellar parameters estimation (e.g. mass, radius and age of stars). Our aim is to quantify systematic errors when the Bayesian method implemented in the PARAM code is applied with various input grids

Validation of the Gaia Early Data Release 3 Parallax Zero-point Model with Asteroseismology
Astronomical Journal, 2021 Gaia Early Data Release 3 (EDR3) provides trigonometric parallaxes for 1.5 billion stars, with reduced systematics compared to Gaia Data Release 2 and reported precisions better by up to a factor of 2.

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.

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

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.

Photometric Stellar Parameters for Asteroseismology and Galactic Studies
, 2014 Asteroseismology has the capability of delivering stellar properties which would otherwise be inaccessible, such as radii, masses and thus ages of stars.

Synergy between asteroseismology and exoplanetary science
, 2021 Over the past decade, space-based asteroseismology has played an important role in the characterization of host stars and their planetary systems. The future looks even brighter, with space missions such as TESS and PLATO ready to take on this legacy. In

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.
