Robust asteroseismic properties of the bright planet host HD 38529
Warrick H. Ball, William J. Chaplin, Martin B. Nielsen +21
The Transiting Exoplanet Survey Satellite (TESS) is recording short-cadence, high duty-cycle timeseries across most of the sky, which presents the opportunity to detect and study o…
On the impact of the structural surface effect on global stellar properties and asteroseismic analyses
Andreas Christ Sølvsten Jørgensen, Josefina Montalbán, George C. Angelou +6
In a series of papers, we have recently demonstrated that it is possible to construct stellar structure models that robustly mimic the stratification of multi-dimensional radiative…
High-precision abundances of elements in solar-type stars. Evidence of two distinct sequences in abundance-age relations
P. E. Nissen, J. Christensen-Dalsgaard, J. R. Mosumgaard +3
HARPS spectra with signal-to-noise ratios S/N > 600 at 6000 A were analysed with MARCS model atmospheres to obtain 1D LTE abundances of C, O, Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Sr…
Detection and characterisation of oscillating red giants: first results from the TESS satellite
Víctor Silva Aguirre, Dennis Stello, Amalie Stokholm +78
Since the onset of the `space revolution' of high-precision high-cadence photometry, asteroseismology has been demonstrated as a powerful tool for informing Galactic archaeology in…
Coupling 1D stellar evolution with 3D-hydrodynamical simulations on-the-fly II: Stellar Evolution and Asteroseismic Applications
Jakob Rørsted Mosumgaard, Andreas Christ Sølvsten Jørgensen, Achim Weiss +2
Models of stellar structure and evolution are an indispensable tool in astrophysics, yet they are known to incorrectly reproduce the outer convective layers of stars. In the first…
The subgiant HR 7322 as an asteroseismic benchmark star
Amalie Stokholm, Poul Erik Nissen, Victor Silva Aguirre +5
We present an in-depth analysis of the bright subgiant HR 7322 (KIC 10005473) using Kepler short-cadence photometry, optical interferometry from CHARA, high-resolution spectra from…
