Theory of Stellar Oscillations [PDF]
, 2017 In recent years, astronomers have witnessed major progresses in the field of stellar physics. This was made possible thanks to the combination of a solid theoretical understanding of the phenomena of stellar pulsations and the availability of a ...

Oscillations in stellar superflares [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Two different mechanisms may act to induce quasi-periodic pulsations (QPP) in whole-disk observations of stellar flares. One mechanism may be magneto-hydromagnetic (MHD) forces and other processes acting on flare loops as seen in the Sun.

Peak Bagging of red giant stars observed by Kepler: first results with a new method based on Bayesian nested sampling [PDF]
EPJ Web of Conferences, 2015 The peak bagging analysis, namely the fitting and identification of single oscillation modes in stars’ power spectra, coupled to the very high-quality light curves of red giant stars observed by Kepler, can play a crucial role for studying stellar ...

Quasi-periodic oscillations of GHz-band polarization in a black hole [PDF]
Nature CommunicationsRelativistic jets from accreting black holes radiate non-thermal emission which is highly variable in different time scales. Previous studies on black holes of different mass scales, including supermassive and stellar-mass black holes, only report flux ...

Axisymmetric bending oscillations of stellar disks [PDF]
The Astrophysical Journal, 1996 Self-gravitating stellar disks with random motion support both exponentially growing and, in some cases, purely oscillatory axisymmetric bending modes, unlike their cold disk counterparts.

Stellar oscillations in TeVeS [PDF]
Journal of Physics: Conference Series, 2010 In this work we examine the oscillation spectra of neutron stars in TeVeS. As a result with Cowling approximation, we find that the frequencies of fundamental modes in TeVeS could become lager than those expected in general relativity, while the dependence of frequency of higher overtone on gravitational theory is stronger than that of lower modes ...

Multiplexed interferometric stellar oscillation spectrometry - MISOS [PDF]
Symposium - International Astronomical Union, 1988 Interferometric spectrometry techniques for measuring stellar oscillations have been developed at Imperial College, resulting in two separate interferometers, the Michelson and the Fabry-Perot based instruments. They have both been used on large telescopes; the Michelson instrument to search for oscillations in solar-type stars and the Fabry-Perot ...

Asteroseismology of Close Binary Stars: Tides and Mass Transfer
Frontiers in Astronomy and Space Sciences, 2021 The study of stellar oscillations allows us to infer the properties of stellar interiors. Meanwhile, fundamental parameters such as mass and radius can be obtained by studying stars in binary systems. The synergy between binarity and asteroseismology can

Solar-Like Oscillators in the Kepler Era: A Review
Frontiers in Astronomy and Space Sciences, 2021 Many late-type stars across the Milky Way exhibit observable pulsations similar to our Sun that open up a window into stellar interiors. The NASA Kepler mission, a space-based photometric telescope, measured the micro-magnitude luminosity fluctuations ...
