  • The Age and Distance of the Kepler Open Cluster NGC 6811 from an Eclipsing Binary, Turnoff Star Pulsation, and Giant Asteroseismology 
    Sandquist, Eric L.; Jessen-Hansen, J.; Shetrone, Matthew D.; Brogaard, Karsten; Meibom, Søren; Leitner, Marika; Stello, Dennis; Bruntt, Hans; Antoci, Victoria; Orosz, Jerome A.; Grundahl, Frank; Frandsen, Søren (2016)
    We present the analysis of an eccentric, partially eclipsing long-period (P = 19.23 days) binary system KIC 9777062 that contains main-sequence stars near the turnoff of the intermediate-age open cluster NGC 6811. The ...
  • Asteroseismology of the Open Clusters NGC 6791, NGC 6811, and NGC 6819 from 19 Months of Kepler Photometry 
    Corsaro, Enrico; Stello, Dennis; Huber, Daniel; Bedding, Timothy R.; Bonanno, Alfio; Brogaard, Karsten; Kallinger, Thomas; Benomar, Othman; White, Timothy R.; Mosser, Benoit; Basu, Sarbani; Chaplin, William J.; Christensen-Dalsgaard, J.; Elsworth, Yvonne P.; García, Rafael A.; Hekker, Saskia; Kjeldsen, Hans; Mathur, Savita; Meibom, Søren; Hall, Jennifer R.; Ibrahim, Khadeejah A.; Klaus, Todd C. (2012)
    We studied solar-like oscillations in 115 red giants in the three open clusters, NGC 6791, NGC 6811, and NGC 6819, based on photometric data covering more than 19 months with NASA's Kepler space telescope. We present ...
  • Detection of Solar-like Oscillations from Kepler Photometry of the Open Cluster NGC 6819 
    Stello, Dennis; Basu, Sarbani; Bruntt, Hans; Mosser, Benoît; Stevens, Ian R.; Brown, Timothy M.; Christensen-Dalsgaard, Jørgen; Gilliland, Ronald L.; Kjeldsen, Hans; Arentoft, Torben; Ballot, Jérôme; Barban, Caroline; Bedding, Timothy R.; Chaplin, William J.; Elsworth, Yvonne P.; García, Rafael A.; Goupil, Marie-Jo; Hekker, Saskia; Huber, Daniel; Mathur, Savita; Meibom, Søren; Sangaralingam, Vinothini; Baldner, Charles S.; Belkacem, Kevin; Biazzo, Katia; Brogaard, Karsten; Suárez, Juan Carlos; D'Antona, Francesca; Demarque, Pierre; Esch, Lisa; Gai, Ning; Grundahl, Frank; Lebreton, Yveline; Jiang, Biwei; Jevtic, Nada; Karoff, Christoffer; Miglio, Andrea; Molenda-Zakowicz, Joanna; Montalbán, Josefina; Noels, Arlette; Roca Cortés, Teodoro; Roxburgh, Ian W.; Serenelli, Aldo M.; Silva Aguirre, Victor; Sterken, Christiaan; Stine, Peter; Szabó, Robert; Weiss, Achim; Borucki, William J.; Koch, David; Jenkins, Jon M. (2010)
    Asteroseismology of stars in clusters has been a long-sought goal because the assumption of a common age, distance, and initial chemical composition allows strong tests of the theory of stellar evolution. We report results ...
  • A Long-period Totally Eclipsing Binary Star at the Turnoff of the Open Cluster NGC 6819 Discovered with Kepler 
    Sandquist, Eric L.; Mathieu, Robert D.; Brogaard, Karsten; Meibom, Søren; Geller, Aaron M.; Orosz, Jerome A.; Milliman, Katelyn E.; Jeffries, Mark W., Jr.; Brewer, Lauren N.; Platais, Imants; Grundahl, Frank; Bruntt, Hans; Frandsen, Søren; Stello, Dennis (2013)
    We present the discovery of the totally eclipsing long-period (P = 771.8 days) binary system WOCS 23009 in the old open cluster NGC 6819 that contains both an evolved star near central hydrogen exhaustion and a low-mass ...
