Saturn's Rings as a Seismograph to Probe Saturn's Internal Structure
AGU Advances, Volume 1, Issue 2, June 2020., 2020 As it has already done for Earth, the Sun, and the stars, seismology has the potential to radically change the way the interiors of giant planets are studied. In a sequence of events foreseen by only a few, observations of Saturn's rings by the Cassini spacecraft have rapidly broken ground on giant planet seismology. Gravity directly couples the planet'

Helio- and asteroseismology [PDF]
Proceedings of the International Astronomical Union, 2001 AbstractObservations of solar and stellar oscillations are providing detailed information about stellar interiors. In the case of the Sun the set of observed frequencies is sufficiently detailed and accurate that the properties of the solar interior, such as sound speed, density and internal rotation, can be inferred with substantial precision and ...

Pulsating stars harbouring planets
EPJ Web of Conferences, 2013 Why bother with asteroseismology while studying exoplanets? There are several answers to this question. Asteroseismology and exoplanetary sciences have much in common and the synergy between the two opens up new aspects in both fields.

Asteroseismology and magnetic cycles [PDF]
Astronomische Nachrichten, 2012 AbstractSmall cyclic variations in the frequencies of acoustic modes are expected to be a common phenomenon in solar‐like pulsators, as a result of stellar magnetic activity cycles. The frequency variations observed throughout the solar and stellar cycles contain information about structural changes that take place inside the stars as well as about ...

Pulsating stars and the Virtual Observatory
EPJ Web of Conferences, 2017 Virtual Observatory is one of the most used internet-based protocols in astronomy. It has become somewhat natural to find, manage, compare, visualize and download observations from very different archives of astronomical observations with no effort.

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.

Modelling Neutron-Star Ocean Dynamics
Universe, 2023 We revisit the calculation of mode oscillations in the ocean of a rotating neutron star, which may be excited during thermonuclear X-ray bursts. Our present theoretical understanding of ocean modes relies heavily on the traditional approximation commonly

Nonanalytic Relativistic r-Modes of Slowly Rotating Nonbarotropic Neutron Stars
Universe, 2022 We show that the r-modes of slowly rotating nonbarotropic neutron stars are described by nonanalytic functions of stellar angular velocity, which makes the perturbation techniques, used so far in the r-mode theoretical studies, inapplicable.

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 ...
