The K2 M67 Study: An Evolved Blue Straggler in M67 from K2 Mission Asteroseismology
Emily Leiner, Robert Mathieu, Dennis Stello +1
Yellow straggler stars (YSSs) fall above the subgiant branch in optical color-magnitude diagrams, between the blue stragglers and the red giants. YSSs may represent a population of…
The K2 M67 Study: Revisiting old friends with K2 reveals oscillating red giants in the open cluster M67
D. Stello, A. Vanderburg, L. Casagrande +6
Observations of stellar clusters have had a tremendous impact in forming our understanding of stellar evolution. The open cluster M67 has a particularly important role as a calibra…
The Detached Eclipsing Binary KV29 and the Age of the Open Cluster M11
Ernest A. Bavarsad, Eric L. Sandquist, Matthew D. Shetrone +1
We present an extensive set of photometry and radial velocities for the detached eclipsing binary KV 29 in the intermediate-aged open cluster M11 (NGC 6705). Spectroscopy shows tha…
The Age and Distance of the Kepler Open Cluster NGC 6811 from an Eclipsing Binary, Turnoff Star Pulsation, and Giant Asteroseismology
Eric L. Sandquist, J. Jessen-Hansen, Matthew D. Shetrone +9
We present the analysis of an eccentric, partially eclipsing long-period ( d) binary system KIC 9777062 that contains main sequence stars near the turnoff of the intermedi…
Detection of solar-like oscillations in relics of the Milky Way: asteroseismology of K giants in M4 using data from the NASA K2 mission
A. Miglio, W. J. Chaplin, K. Brogaard +18
Asteroseismic constraints on K giants make it possible to infer radii, masses and ages of tens of thousands of field stars. Tests against independent estimates of these properties…
Determining the Age of the Kepler Open Cluster NGC 6819 With a New Triple System and Other Eclipsing Binary Stars
Lauren N. Brewer, Eric L. Sandquist, Robert D. Mathieu +10
As part of our study of the old (~2.5 Gyr) open cluster NGC 6819 in the Kepler field, we present photometric (Kepler and ground-based BVRcIc) and spectroscopic observations of the…
