A Criterion for Magnetars Producing Giant Flares

Y. Meng, Q. -S. Zhang, J. Lin

In this work, the straight flux rope in the model of giant flares on magnetars (Meng et al. 2014) was replaced with a curved one and the equilibrium behavior of the flux rope was i…

Asteroseismic investigation on KIC 10526294 to probe convective core overshoot mixing

Qian-Sheng Zhang, Li Yan, Wu Tao +1

In the overshoot mixing model with an exponentially decreasing diffusion coefficient, the initial value of the diffusion coefficient plays a crucial role. According to the turbulen…

Evolution of Dipolar Mixed-mode Coupling Factor in Red Giant Stars: Impact of Buoyancy Spike

Chen Jiang, Margarida Cunha, Joergen Christensen-Dalsgaard +2

Mixed modes observed in red giants allow for investigation of the stellar interior structures. One important feature in these structures is the buoyancy spike caused by the discont…

Core overshoot constrained by the absence of a solar convective core and some solar-like stars

Qian-Sheng Zhang, Jørgen Christensen-Dalsgaard, Yan Li

Convective-core overshoot mixing is a significant uncertainty in stellar evolution. Because numerical simulations and turbulent convection models predict exponentially decreasing r…

Can small-scale magnetic fields be the major cause for the near-surface effect of the solar p-mode frequencies?

Yan Li, Qian-sheng Zhang, Tao Wu +5

Small-scale magnetic fields are not only the fundamental element of the solar magnetism, but also closely related to the structure of the solar atmosphere. The observations have sh…

Solar models with convective overshoot, the solar-wind mass loss, and a PMS disk accretion: helioseismic quantities, Li depletion and neutrino fluxes

Qian-Sheng Zhang, Yan Li, Jørgen Christensen-Dalsgaard

Helioseismic observations have revealed many properties of the Sun: the depth and the helium abundance of the convection zone, the sound-speed and the density profiles in the solar…
