Transverse loop oscillations observed by the Atmospheric Imaging Assembly (AIA) instrument on the Solar Dynamics Observatory (SDO) spacecraft are studied after an impulsive solar flare eruption on 2012 May 8. We have found that a transversely oscillating coronal loop seen in the 171 Å bandpass oscillates in anti-phase with respect to adjacent larger loops seen in the 193 Å and 211 Å bandpasses....

Transverse oscillations of small amplitude are commonly seen in highresolution observations of filament threads, i.e. the fine-structures of solar filaments/prominences, and are typically damped in a few periods. Kink wave modes supported by the thread body offer a consistent explanation of these observed oscillations. Among the proposed mechanisms to explain the kink mode damping, resonant abs...

Localized differences between the real Sun and standard solar models are shown to be small. The sound speeds of the real and the standard model Suns typically differ by less than 0.3% for regions of radial width 30.1 RJ in the solar core.

The five-minute oscillations in the Sun have provided a wealth of information about the solar interior. After many attempts, positive detections of similar oscillations in solar-type stars have now been made. This review discusses the properties of solar-like oscillations, the methods used to observe them and the results on individual stars. We conclude that the study of solar-like oscillations...

We report here, for the Ðrst time, on spatial oscillations of coronal loops, which were detected in extreme-ultraviolet wavelengths (171 with the T ransition Region and Coronal Explorer, in the temAŽ ) perature range of MK. The observed loop oscillations occurred during a Ñare that began at T e B 1.0È1.5 1998 July 14, 12 :55 UT and are most prominent during the Ðrst 20 minutes. The oscillating ...

Singular spectrum analysis, a technique to detect oscillations in short and noisy time series, was Ðrst developed for geophysical applications. This work o†ers a generalization for long and noisy time series in astrophysical applications. The motivating problem is the detection of low-amplitude solar oscillations.

An understanding of stellar acoustic oscillations is attempted, using the local wave concept in semi-analytical calculations. The local homogeneity approximation allows to obtain simplified equations that can nevertheless describe the wave behavior down to the central region, as the gravitational potential perturbation is not neglected. Acoustic modes are calculated as classical standing waves ...
