K-dwarf Radius Inflation and a 10-Gyr Spin-down Clock Unveiled through Asteroseismology of HD 219134 from the Keck Planet Finder
Yaguang Li, Daniel Huber, J. M. Joel Ong +26
We present the first asteroseismic analysis of the K3\,V planet host HD~219134, based on four consecutive nights of radial velocities collected with the Keck Planet Finder. We appl…
Fundamental physics with Espresso: Towards an accurate wavelength calibration for a precision test of the fine-structure constant
Tobias M. Schmidt, Paolo Molaro, Michael T. Murphy +56
Observations of metal absorption systems in the spectra of distant quasars allow to constrain a possible variation of the fine-structure constant throughout the history of the Univ…
Nightside condensation of iron in an ultra-hot giant exoplanet
David Ehrenreich, Christophe Lovis, Romain Allart +94
Ultra-hot giant exoplanets receive thousands of times Earth's insolation. Their high-temperature atmospheres (>2,000 K) are ideal laboratories for studying extreme planetary climat…
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…
Rotation and pulsation in Ap stars: first light results from TESS sectors 1 and 2
M. S. Cunha, V. Antoci, D. L. Holdsworth +36
We present the first results from the Transiting Exoplanet Survey Satellite (TESS) on the rotational and pulsational variability of magnetic chemically peculiar A-type stars. We an…
SIGS - Seismic Inferences for Glitches in Stars
L. F. R. Pereira, J. P. Faria, M. J. P. F. G. Monteiro
The increased amount of high precision seismic data for solar-like stars calls for the existence of tools that can extract information from such data. In the case of the study of a…
Deciphering the period spacing pattern in the oscillation spectrum of the SPB star KIC 7760680
Wojciech Szewczuk, Jadwiga Daszyńska-Daszkiewicz, Przemysław Walczak
We present the analysis of KIC 7760680, the rotating Slowly Pulsating B-type star identified in the Kepler photometry. The oscillation spectrum of the star exhibits a series of 36…
The SpaceInn-SISMA database: characterization of a large sample of variable and active stars by means of HARPS spectra
M. Rainer, E. Poretti, A. Mistò +6
We created a large database of physical parameters and variability indicators by fully reducing and analysing the large number of spectra taken to complement the asteroseismic obse…
The PLATO 2.0 Mission
H. Rauer, C. Catala, C. Aerts +159
PLATO 2.0 has recently been selected for ESA's M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it…
A large sample of calibration stars for Gaia: log g from Kepler and CoRoT
O. L. Creevey, F. Thévenin, S. Basu +6
Asteroseismic data can be used to determine surface gravities with precisions of < 0.05 dex by using the global seismic quantities Deltanu and nu_max along with Teff and [Fe/H]. Su…
Successful Asteroseismology for a Better Characterization of the Exoplanet HAT-P-7b
M. Oshagh, A. Grigahcène, O. Benomar +4
It is well known that asteroseismology is the unique technique permitting the study of the internal structure of pulsating stars using their pulsational frequencies, which is per s…
Characterizing two solar-type Kepler subgiants with asteroseismology: KIC10920273 and KIC11395018
G. Dogan, T. S. Metcalfe, S. Deheuvels +27
Determining fundamental properties of stars through stellar modeling has improved substantially due to recent advances in asteroseismology. Thanks to the unprecedented data quality…
On the possibility of using seismic probes to study the core composition in pulsating white dwarfs
J. P. Faria, M. J. P. F. G. Monteiro
White dwarfs correspond to the final stages of stellar evolution of solar-type stars. In these objects, production of energy by nuclear burning has ended which means that a white d…
Fundamental Properties of Stars using Asteroseismology from Kepler & CoRoT and Interferometry from the CHARA Array
D. Huber, M. J. Ireland, T. R. Bedding +37
We present results of a long-baseline interferometry campaign using the PAVO beam combiner at the CHARA Array to measure the angular sizes of five main-sequence stars, one subgiant…
Atmospheric parameters and pulsational properties for a sample of \,Sct, \,Dor, and hybrid {\it Kepler} targets
G. Catanzaro, V. Ripepi, S. Bernabei +14
We report spectroscopic observations for 19 \,Sct candidates observed by the {\it Kepler} satellite both in long and short cadence mode. For all these stars, by using spectral s…
