Co-existence of Internal Gravity Waves and Tayler-Spruit Magnetic Fields in the Radiative Core of Low-mass Stars

L. Amard, S. Mathis

The Tayler-Spruit dynamo (TSD) is able to generate a small-scale magnetic field in the differentially rotating stably stratified layers of stars and was recently observed in numeri…

Exploring hydrodynamical stellar tachoclines along stellar evolution

Camille Moisset, Stéphane Mathis, Louis Amard

Stellar tachoclines are thin regions located between the radiative core and the convective envelope of solar-type stars. They are defined as layers where the rotation of the radiat…

Spectroscopic Follow-up of Young High- Dwarf Star Candidates: Still Likely Genuinely Young

Yuxi Lu, Catherine Manea, Maryum Sayeed +9

The question of whether genuinely young high- stars exist has been discussed for over a decade since their discovery from asteroseismology of giant stars as it is challenging to…

Modelling the effect of stellar metallicity on the XUV evolution of low-mass stars and its impact on exoplanet atmospheres/habitability

Victor See, Charlotte Fairman, Louis Amard +1

Understanding how exoplanet atmospheres evolve is a key question in the context of habitability. One key process governing this evolution is atmospheric evaporation by stellar X-ra…

The magnetic and spin-down properties of slowly rotating fully convective M dwarfs

Victor See, Louis Amard, Stefano Bellotti +19

The evolution of the magnetism, winds and rotation of low-mass stars are all linked. One of the most common ways to probe the magnetic properties of low-mass stars is with the Zeem…

Magnetic activity evolution of solar-like stars: II. -Ro evolution of Kepler main-sequence targets

Savita Mathur, Angela R. G. Santos, Zachary R. Claytor +16

There is now a large sample of stars observed by the Kepler satellite with measured rotation periods and photometric activity index . We use this data, in conjunction w…
