Pulsating stars and the Virtual Observatory

open access: yesEPJ Web of Conferences, 2017
Virtual Observatory is one of the most used internet-based protocols in astronomy. It has become somewhat natural to find, manage, compare, visualize and download observations from very different archives of astronomical observations with no effort.

Asteroseismology of solar-type stars [PDF]

open access: yesLiving Reviews in Solar Physics, 2019
Until the last few decades, investigations of stellar interiors had been restricted to theoretical studies only constrained by observations of their global properties and external characteristics.

Age determination of galaxy merger remnant stars using asteroseismology [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2021
The Milky Way was shaped by the mergers with several galaxies in the past. We search for remnant stars that were born in these foreign galaxies and assess their ages in an effort to put upper limits on the merger times and thereby better understand the

Asteroseismology and magnetic cycles [PDF]

open access: yesAstronomische Nachrichten, 2012
AbstractSmall cyclic variations in the frequencies of acoustic modes are expected to be a common phenomenon in solar‐like pulsators, as a result of stellar magnetic activity cycles. The frequency variations observed throughout the solar and stellar cycles contain information about structural changes that take place inside the stars as well as about ...

Solar-Like Oscillators in the Kepler Era: A Review

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Many late-type stars across the Milky Way exhibit observable pulsations similar to our Sun that open up a window into stellar interiors. The NASA Kepler mission, a space-based photometric telescope, measured the micro-magnitude luminosity fluctuations ...

The Hot Limit of Solar-like Oscillations From Kepler Photometry

open access: yesFrontiers 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.

Tracking the Evolution of Lithium in Giants Using Asteroseismology: Super-Li-rich Stars Are Almost Exclusively Young Red-clump Stars [PDF]

open access: yesAstrophysical Journal Letters, 2021
We report novel observational evidence on the evolutionary status of lithium-rich giant stars by combining asteroseismic and lithium abundance data. Comparing observations and models of the asteroseismic gravity-mode period spacing ΔΠ1, we find that ...

PLATO as it is: A legacy mission for Galactic archaeology

open access: yesAstronomische Nachrichten, Volume 338, Issue 6, Page 644-661, July 2017., 2017
Deciphering the assembly history of the Milky Way is a formidable task, which becomes possible only if one can produce high‐resolution chrono‐chemo‐kinematical maps of the Galaxy. Data from large‐scale astrometric and spectroscopic surveys will soon provide us with a well‐defined view of the current chemo‐kinematical structure of the Milky Way, but it ...

On the Nature of the Core of α Centauri A: The Impact of the Metallicity Mixture

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Forward asteroseismic modeling plays an important role toward a complete understanding of the physics taking place in deep stellar interiors. With a dynamical mass in the range over which models develop convective cores while in the main sequence, the ...
