Synergy between asteroseismology and exoplanet science: an outlook [PDF]

, 2018
Space-based asteroseismology has been playing an important role in the characterization of exoplanet-host stars and their planetary systems. The future looks even brighter, with space missions such as NASA's TESS and ESA's PLATO ready to take on this ...

Core-envelope coupling of gravito-inertial waves in pre-main-sequence solar-type stars

Astronomy & Astrophysics
The recent detection of solar equatorial Rossby waves has renewed interest in the study of gravito-inertial waves propagating in the convective envelope of solar-type stars.

LS IV — 14°116 : A Time-Resolved Spectroscopic Study

Open Astronomy, 2017
LSIV-14 116 is a very unusual subdwarf B star. It pulsates non-radially with high-order g-modes, these pulsations are unexpected and unexplained, as the effective temperature is 6 000K hotter than the blue edge of the hot subdwarf g-mode instability ...

Fast and Automated Oscillation Frequency Extraction Using Bayesian Multi-Modality

Frontiers in Astronomy and Space Sciences, 2019
Since the advent of CoRoT, and NASA Kepler and K2, the number of low- and intermediate-mass stars classified as pulsators has increased very rapidly with time, now accounting for several 104 targets.

Seismic detection of core magnetic fields in red giants using the gravity offset

Astronomy & Astrophysics
Context. Magnetic fields are known to efficiently redistribute angular momentum in stars. Recently, magnetic fields have been measured in the cores of red giant stars using asteroseismology, and it was shown that core magnetic fields, if unaccounted for,

Bolometric corrections of stellar oscillation mode amplitudes as observed by the PLATO mission

Astronomy & Astrophysics
Aims. We derive bolometric correction functions for oscillation mode amplitudes observed by the different cameras of the ESA PLATO mission. Such corrections between bolometric (full light) and mission instrument-specific amplitudes enable comparisons to ...

Isochrone-cloud fitting and asteroseismology of the Kepler open cluster NGC 6866

Astronomy & Astrophysics
Context. Isochrone fitting is a classical method used to determine the ages of open clusters. However, the derived ages depend strongly on the chosen input physics of the stellar models used to deduce the isochrones.

The Hot Limit of Solar-like Oscillations From Kepler Photometry

Frontiers in Astronomy and Space Sciences, 2020
Kepler short-cadence photometry of 2,347 stars with effective temperatures in the range 6,000–10,000 K was used to search for the presence of solar-like oscillations.

Asteroseismology of solar-type and red-giant stars

, 2013
We are entering a golden era for stellar physics driven by satellite and telescope observations of unprecedented quality and scope. New insights on stellar evolution and stellar interiors physics are being made possible by asteroseismology, the study of ...
