Journal ArticleDOI
Age and helium content of the open cluster NGC 6791 from multiple eclipsing binary members - II. Age dependencies and new insights
Karsten Brogaard,Karsten Brogaard,Don A. VandenBerg,Hans Bruntt,Frank Grundahl,S. Frandsen,Luigi R. Bedin,Luigi R. Bedin,Antonino Milone,Aaron Dotter,Gregory A. Feiden,Peter B. Stetson,Eric L. Sandquist,Andrea Miglio,Dennis Stello,Jens Jessen-Hansen +15 more
TL;DR: In this paper, the authors used multiple detached eclipsing binaries for determining stellar cluster ages, which were previously out of reach, to constrain parameters of stellar models, notably the helium content, and provided firm constraints that stellar models must reproduce.
Journal ArticleDOI
What Asteroseismology can do for Exoplanets: Kepler-410A b is a Small Neptune around a Bright Star, in an Eccentric Orbit Consistent with Low Obliquity
V. Van Eylen,V. Van Eylen,Mikkel N. Lund,Mikkel N. Lund,V. Silva Aguirre,Torben Arentoft,Hans Kjeldsen,Simon Albrecht,William J. Chaplin,Howard Isaacson,M. G. Pedersen,Jens Jessen-Hansen,Brandon Tingley,Jørgen Christensen-Dalsgaard,Conny Aerts,Tiago L. Campante,Stephen T. Bryson +16 more
TL;DR: In this article, a Neptune-sized exoplanet, Kepler-410A b (KOI-42b), was confirmed to be a planet with a 17.8 day, eccentric orbit around the bright (K {sub p} = 9.4) star Kepler410A (Kepler-410B), which is the third brightest confirmed planet host star in the Kepler field.

What asteroseismology can do for exoplanets: Kepler-410A b is a Small Neptune around a bright star, in an eccentric orbit consistent with low obliquity

TL;DR: In this article, the authors confirm the Kepler planet candidate Kepler-410b (KOI-42b) as a Neptune sized exoplanet on a 17.8 day, eccentric orbit around the bright (Kp = 9.4) star Kepler410A. This is the third brightest confirmed planet host star in the Kepler field and one of the brightest hosts of all currently known transiting exoplanets.
Journal ArticleDOI
