Geophysical Research Letters, 2022 Magnetospheric sawtooth oscillations are observed during strong and steady solar wind driving conditions. The simulation results of our global magnetohydrodynamics (MHD) model with embedded kinetic physics show that when the total magnetic flux carried ...

Proceedings of the International Astronomical Union, 2008 AbstractStudy of solar oscillations has provided us detailed information about solar structure and dynamics. These in turn provide a test of theories of stellar structure and evolution as well as theories of angular momentum transfer and dynamo. Some of these results about the solar structure and its implication on the recent revision of heavy element ...

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.

A Statistical Study of Short-period Decayless Oscillations of Coronal Loops in an Active Region
The Astrophysical Journal, 2023 Coronal loop oscillations are common phenomena in the solar corona, which are often classified as decaying and decayless oscillations. Using the high-resolution observation measured by the Extreme Ultraviolet Imager (EUI) on board the Solar Orbiter, we ...

Standing oscillations in a resonant sunspot atmosphere captured by integral field spectroscopy
Frontiers in Astronomy and Space SciencesThe solar atmosphere is replete with magnetohydrodynamic wave activity, with magnetic structures such as sunspots and pores able to channel wave energy flux efficiently into the outer atmosphere. Steep density and temperature gradients at the base of the

The Astrophysical Journal, 2023 The shear flow influences the stability of magnetohydrodynamic (MHD) waves. In the presence of a dissipation mechanism, flow shear may induce an MHD wave instability below the threshold of the Kelvin–Helmholtz instability, which is called dissipative ...

Solar Oscillations and Convection. II. Excitation of Radial Oscillations [PDF]
The Astrophysical Journal, 2001 Solar p-mode oscillations are excited by the work of stochastic, non-adiabatic, pressure fluctuations on the compressive modes. We evaluate the expression for the radial mode excitation rate derived by Nordlund and Stein (Paper I) using numerical simulations of near surface solar convection.

Evidence of 5 minute Oscillations from Parker Solar Probe
The Astrophysical Journal LettersThe Sun’s surface vibrates in characteristic 5 minute oscillations, known as p -modes, generated by sound waves trapped within the convection zone. Although these oscillations have long been hypothesized to reach into the solar wind, direct in situ ...
