TL;DR: In this paper, a simple test is developed to estimate the detectability of solar-like oscillations in TESS photometry of any given star, based on an all-sky stellar and planetary synthetic population.

TL;DR: In this paper, the authors measured the stellar inclination via asteroseismology for an ensemble of 25 solar-type hosts observed with NASA's Kepler satellite and showed that the results are consistent with alignment at the 2-$σ$ level for all stars in the sample, meaning that the system surrounding the red-giant star Kepler-56 remains as the only unambiguous multiple-planet system detected to date.

TL;DR: In this paper, a new analysis of the Gaia DR2 parallax offset for nearly 3000 red-giant branch (RGB) and 2200 red clump (RC) stars observed by Kepler, as well as about 500 and 700 red giants (all either in the RGB or RC phase) selected by the K2 Galactic Archaeology Program in campaigns 3 and 6.
Journal ArticleDOI
Testing asteroseismology with Gaia DR2: hierarchical models of the Red Clump
Oliver J. Hall,Oliver J. Hall,Guy R. Davies,Guy R. Davies,Yvonne Elsworth,Yvonne Elsworth,Andrea Miglio,Andrea Miglio,Timothy R. Bedding,Timothy R. Bedding,Anthony G. A. Brown,Saniya Khan,Saniya Khan,Keith Hawkins,Rafael A. García,Rafael A. García,William J. Chaplin,William J. Chaplin,Thomas S. H. North +18 more
TL;DR: In this article, the authors measured how the magnitude and spread of the Red Clump (RC) stars in the Kepler field are affected by changes to temperature and scaling relations for seismology, and changes to the parallax zero-point for Gaia.
Journal ArticleDOI

TL;DR: In this paper, the authors report the discovery of K2-132b, an inflated gas giant planet found with the NASA K2 mission, and a revised mass for another inflated planet, K2 -97b.
