Standing on the shoulders of Dwarfs: the Kepler asteroseismic LEGACY sample II - radii, masses, and ages
Victor Silva Aguirre, Mikkel N. Lund, H. M. Antia +21
We use asteroseismic data from the Kepler satellite to determine fundamental stellar properties of the 66 main-sequence targets observed for at least one full year by the mission.…
Standing on the shoulders of Dwarfs: the asteroseismic LEGACY sample I - oscillation mode parameters
Mikkel N. Lund, Víctor Silva Aguirre, Guy R. Davies +17
The advent of space-based missions like has revolutionized the study of solar-type stars, particularly through the measurement and modeling of their resonant modes of osci…
The Solar Twin Planet Search. V. Close-in, low-mass planet candidates and evidence of planet accretion in the solar twin HIP 68468
Jorge Melendez, Megan Bedell, Jacob L. Bean +14
[Methods]. We obtained high-precision radial velocities with HARPS on the ESO 3.6 m telescope and determined precise stellar elemental abundances (~0.01 dex) using MIKE spectra on…
Testing stellar evolution models with the retired A star HD 185351
Jakob G. Hjørringgaard, Victor Silva Aguirre, Tim R. White +5
The physical parameters of the retired A star HD 185351 were analysed in great detail by Johnson et al. (2014) using interferometry, spectroscopy and asteroseismology. Results from…
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…
Asteroseismic properties of solar-type stars observed with the NASA K2 mission: results from Campaigns 1-3 and prospects for future observations
Mikkel N. Lund, William J. Chaplin, Luca Casagrande +10
We present an asteroseismic analysis of 33 solar-type stars observed in short cadence during Campaigns (C) 1-3 of the NASA K2 mission. We were able to extract both average seismic…
