Limits on surface gravities of Kepler planet-candidate host stars from non-detection of solar-like oscillations [PDF]
, 2014 We present a novel method for estimating lower-limit surface gravities log g of Kepler targets whose data do not allow the detection of solar-like oscillations.

Three-dimensional MHD Simulations of Solar Prominence Oscillations in a Magnetic Flux Rope [PDF]
, 2018 Solar prominences are subject to all kinds of perturbations during their lifetime, and frequently demonstrate oscillations. The study of prominence oscillations provides an alternative way to investigate their internal magnetic and thermal structures ...

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 ...

Transient solar oscillations driven by primordial black holes. [PDF]
Physical Review Letters, 2011 Stars are transparent to the passage of primordial black holes (PBHs) and serve as seismic detectors for such objects. The gravitational field of a PBH squeezes a star and causes it to ring acoustically.

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 ...

Large-amplitude Longitudinal Oscillations in a Solar Filament [PDF]
, 2017 In this paper, we report our multiwavelength observations of the large-amplitude longitudinal oscillations of a filament observed on 2015 May 3. Located next to active region 12335, the sigmoidal filament was observed by the ground-based Hα telescopes ...

Annals of Geophysics, 1996 The results of Lastovicka and Mlch (1994) and Altadill and Lastovicka (1996) are extended by the use of f0F2 and h'F data from Juliusruh, Lannion and Rome.

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.

Catalog of Decaying Kink Oscillations of Coronal Loops in the 24th Solar Cycle
Astrophysical Journal Supplement Series, 2019 A catalog of kink oscillations of solar coronal loops, which spans during almost all of solar cycle 24, is presented. The catalog is based on the observations made in the extreme ultraviolet band at 171 Å with Solar Dynamics Observatory/Atmospheric ...

Astrophysical Journal, 2019 Rapidly decaying oscillations of the thermal emission detected in the decay phase of solar and stellar flares are usually interpreted as standing or sloshing (reflecting) slow magnetoacoustic oscillations.
