Seismic performance
B. Mosser, E. Michel, R. Samadi +4
Asteroseismology is a unique tool that can be used to study the interior of stars and hence deliver unique information for the studiy of stellar physics, stellar evolution, and Gal…
FliPer: Classifying TESS pulsating stars
L. Bugnet, R. A. García, G. R. Davies +3
The recently launched NASA Transiting Exoplanet Survey Satellite (TESS) mission is going to collect lightcurves for a few hundred million of stars and we expect to increase the num…
FliPer: A global measure of power density to estimate surface gravities of main-sequence Solar-like stars and red giants
L. Bugnet, R. A. García, G. R. Davies +4
Asteroseismology provides global stellar parameters such as masses, radii or surface gravities using the mean global seismic parameters as well as the effective temperature for tho…
A synthetic sample of short-cadence solar-like oscillators for TESS
Warrick H. Ball, William J. Chaplin, Mathew Schofield +4
NASA's Transiting Exoplanet Survey Satellite (TESS) has begun a two-year survey of most of the sky, which will include lightcurves for thousands of solar-like oscillators sampled a…
Mean density inversions for red giants and red clump stars
Gaël Buldgen, B. Rendle, T. Sonoi +8
Since the CoRoT and Kepler missions, the availability of high quality seismic spectra for red giants has made them the standard clocks and rulers for Galactic Archeology. With the…
Masses and ages for metal-poor stars: a pilot program combining asteroseismology and high-resolution spectroscopic follow-up of RAVE halo stars
M. Valentini, C. Chiappini, D. Bossini +10
Very metal-poor halo stars are the best candidates for being among the oldest objects in our Galaxy. Samples of halo stars with age determination and detailed chemical composition…
Signatures of Solar Cycle 25 in Subsurface Zonal Flows
R. Howe, F. Hill, R. Komm +5
The pattern of migrating zonal flow bands associated with the solar cycle, known as the torsional oscillation, has been monitored with continuous global helioseismic observations b…
Stellar Surface Magneto-Convection as a Source of Astrophysical Noise II. Center-to-Limb Parameterisation of Absorption Line Profiles and Comparison to Observations
H. M. Cegla, C. A. Watson, S. Shelyag +6
Manifestations of stellar activity (such as star-spots, plage/faculae, and convective flows) are well known to induce spectroscopic signals often referred to as astrophysical noise…
Empirical relations for the accurate estimation of stellar masses and radii
Andy Moya, Federico Zuccarino, William J. Chaplin +1
In this work, we have taken advantage of the most recent accurate stellar characterizations carried out using asteroseismology, eclipsing binaries and interferometry to evaluate a…
Signatures of magnetic activity in the seismic data of solar-type stars observed by Kepler
A. R. G. Santos, T. L. Campante, W. J. Chaplin +8
In the Sun, the frequencies of the acoustic modes are observed to vary in phase with the magnetic activity level. These frequency variations are expected to be common in solar-type…
The Red-Giant Branch Bump Revisited: Constraints on Envelope Overshooting in a Wide Range of Masses and Metallicities
Saniya Khan, Oliver J. Hall, Andrea Miglio +4
The red-giant branch bump provides valuable information for the investigation of the internal structure of low-mass stars. Because current models are unable to accurately predict t…
Establishing the accuracy of asteroseismic mass and radius estimates of giant stars. I. Three eclipsing systems at [Fe/H]~ -0.3 and the need for a large high-precision sample
K. Brogaard, C. J. Hansen, A. Miglio +12
We aim to establish and improve the accuracy level of asteroseismic estimates of mass, radius, and age of giant stars. This can be achieved by measuring independent, accurate, and…
