Sentences with phrase «used asteroseismology»

We used asteroseismology to measure a large obliquity for Kepler - 56, a red giant... ▽ More Stars hosting hot Jupiters are often observed to have high obliquities, whereas stars with multiple co-planar planets have been seen to have low obliquities.

We used asteroseismology to measure a large obliquity for Kepler - 56, a red giant star hosting two transiting co-planar planets.

Abstract: We have used asteroseismology to determine fundamental properties for 66 Kepler planet - candidate host stars, with typical uncertainties of 3 % and 7 % in radius and mass, respectively.

The results include new asteroseismic solutions for four host stars with confirmed planets (Kepler - 4, Kepler - 14, Kepler - 23 and Kepler - 25) and increase the total number of Kepler host stars with asteroseismic solutions... ▽ More We have used asteroseismology to determine fundamental properties for 66 Kepler planet - candidate host stars, with typical uncertainties of 3 % and 7 % in radius and mass, respectively.

The scientists used asteroseismology to characterize the stars and their planets to levels of accuracy not achieved before for these systems.

Here we use asteroseismology to measure the inclination angles of spin axes in 48 stars from the two old open clusters NGC ~ 6791 and NGC ~ 6819.

We use broadband photometry and asteroseismology to characterize 11,532 Kepler targets which were previously unclassified in the Kepler Input Catalog (KIC).

The accurate asteroseismic determinations now available for large number of stars in the Kepler fields can be used to check and calibrate surface gravities that are currently being obtained spectroscopically for a huge numbers of stars targeted by large - scale spectroscopic surveys, such as the on - going Large Sky Area... ▽ More Asteroseismology allows for deriving precise values of surface gravity of stars.

This is one... ▽ More We describe three useful applications of asteroseismology in the context of exoplanet science: (1) the detailed characterisation of exoplanet host stars; (2) the measurement of stellar inclinations; and (3) the determination of orbital eccentricity from transit duration making use of asteroseismic stellar densities.

We also briefly describe how we can identify cluster stars that have evolved through non-standard evolution by making use of ensemble asteroseismology.
