Precise Age For The Binary HD 21278 In The Young Alpha Persei Cluster

Christopher A. Danner, Eric L. Sandquist, Gail H. Schaefer +14

We present a study of the double-lined spectroscopic binary HD 21278 that contains one of the brightest main sequence stars in the young Persei open cluster. We analyzed new sp…

Asteroseismic Study of Subgiants and Giants of the Open Cluster M67 using Kepler/K2: Expanded Sample and Precise Masses

Claudia Reyes, Dennis Stello, Marc Hon +7

Sparked by the asteroseismic space revolution, ensemble studies have been used to produce empirical relations linking observed seismic properties and fundamental stellar properties…

Isochrone fitting to the open cluster M67 in the era of Gaia and improved model physics

Claudia Reyes, Dennis Stello, Marc Hon +3

The Gaia mission has provided highly accurate observations that have significantly reduced the scatter in the colour-magnitude diagrams of open clusters. As a result of the improve…

An asteroseismic age estimate of the open cluster NGC 6866 using Kepler and Gaia

K. Brogaard, T. Arentoft, A. Miglio +10

Asteroseismology of solar-like oscillations in giant stars allow the derivation of their masses and radii. For members of open clusters this allows an age estimate of the cluster w…

Precise Age for the Binary Star System 12 Com in the Coma Berenices Cluster

Rex Lam, Eric L. Sandquist, Gail H. Schaefer +11

We present measurements of the interferometrically-resolved binary star system 12 Com and the single giant star 31 Com in the cluster Coma Berenices. 12 Com is a double-lined spect…

Evolved Eclipsing Binaries and the Age of the Open Cluster NGC 752

Eric L. Sandquist, Andrew J. Buckner, Matthew D. Shetrone +8

We present analyses of improved photometric and spectroscopic observations for two detached eclipsing binaries at the turnoff of the open cluster NGC 752: the 1.01 day binary DS An…
