Asteroseismology of solar-type stars [PDF]

Living Reviews in Solar Physics, 2019
AbstractUntil 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. However, in the last 30 years the field has been revolutionized by the ability to perform seismic investigations of stellar interiors.

The magnetic fields, activity and hidden companions of solar-type stars [PDF]

, 2023
The magnetic fields of the Sun and other solar-type stars manifest in a range of observable surface phenomena that provide insight into the magnetic dynamos operating within, but also hamper the detection of exoplanets.

The winds of young Solar-type stars in the Pleiades, AB Doradus, Columba and $\beta$ Pictoris [PDF]

, 2023
Solar-type stars, which shed angular momentum via magnetised stellar winds, enter the main sequence with a wide range of rotational periods $P_\text{rot}$. This initially wide range of rotational periods contracts and has mostly vanished by a stellar age

CONVECTION IN OBLATE SOLAR-TYPE STARS [PDF]

The Astrophysical Journal, 2016
ABSTRACT We present the first global 3D simulations of thermal convection in the oblate envelopes of rapidly rotating solar-type stars. This has been achieved by exploiting the capabilities of the new compressible high-order unstructured spectral difference (CHORUS) code.

The winds of young Solar-type stars in the Hyades [PDF]

, 2021
International audienceABSTRACT Stellar winds govern the spin-down of Solar-type stars as they age, and play an important role in determining planetary habitability, as powerful winds can lead to atmospheric erosion.

Evolution of brightness and magnetic features of young solar-type stars – II. The young F8 star HIP 71933 [PDF]

, 2023
The early, active history of our Sun is still not fully understood. Observations of the magnetic fields on active young solar-type stars allow us an insight into the early evolution of our Sun.

Zeeman-Doppler imaging of five young solar-type stars [PDF]

, 2022
The magnetic activity of the Sun changes with the solar cycle. Similar cycles are found in other stars as well, but their details are not known to a similar degree.

DYNAMICAL MODEL FOR SPINDOWN OF SOLAR-TYPE STARS [PDF]

The Astrophysical Journal, 2016
ABSTRACT After their formation, stars slow down their rotation rates by the removal of angular momentum from their surfaces, e.g., via stellar winds. Explaining how this rotation of solar-type stars evolves in time is currently an interesting but difficult problem in astrophysics.

The winds of young Solar-type stars in Coma Berenices and Hercules-Lyra [PDF]

, 2022
We present wind models of 10 young Solar-type stars in the Hercules-Lyra association and the Coma Berenices cluster aged around ∼0.26 and ∼0.58 Gyr, respectively.

Asteroseismology of Solar-Type and Red-Giant Stars [PDF]

Annual Review of Astronomy and Astrophysics, 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 stars by the observation of natural, resonant oscillations.
