Red giant seismology: Observations [PDF]
EPJ Web of Conferences, 2013 The CoRoT and Kepler missions provide us with thousands of red-giant light curves that allow a very precise asteroseismic study of these objects. Before CoRoT and Kepler, the red-giant oscillation patterns remained obscure.

Rapidly rotating red giants [PDF]
EPJ Web of Conferences, 2017 Stellar oscillations give seismic information on the internal properties of stars. Red giants are targets of interest since they present mixed modes, wich behave as pressure modes in the convective envelope and as gravity modes in the radiative core ...

Internal rotation of red giants by asteroseismology [PDF]
EPJ Web of Conferences, 2013 We present an asteroseismic approach to study the dynamics of the stellar interior in red giant stars by asteroseismic inversion of the splittings induced by the stellar rotation on the oscillation frequencies.

International Astronomical Union Colloquium, 1988 AbstractTwo principal mechanisms that may be responsible for mass loss from red giants are considered: shock wave-driven winds and radiatively (dust)-driven winds. Effect of the periodic shocks accompanying nonlinear oscillations of red giants is most prominent in the outer layers of the stellar atmosphere where shocks are able not only to expel gas ...

Probing the Deep End of the Milky Way with New Oscillating Kepler Giants [PDF]
EPJ Web of Conferences, 2017 The Kepler mission has been a success in both exoplanet search and stellar physics studies. Red giants have actually been quite a highlight in the Kepler scene.

Asteroseismology of red giants & galactic archaeology [PDF]
, 2017 Red-giant stars are low- to intermediate-mass ($M \lesssim 10$~M$_{\odot}$) stars that have exhausted hydrogen in the core. These extended, cool and hence red stars are key targets for stellar evolution studies as well as galactic studies for several reasons: a) many stars go through a red-giant phase; b) red giants are intrinsically bright; c) large ...

Red-giant stars in eccentric binaries [PDF]
EPJ Web of Conferences, 2015 The unparalleled photometric data obtained by NASA’s Kepler Space Telescope has led to improved understanding of red-giant stars and binary stars. We discuss the characterization of known eccentric system, containing a solar-like oscillating red-giant ...

The Aarhus red giants challenge [PDF]
Astronomy & Astrophysics, 2020 Contact. The large quantity of high-quality asteroseismic data that have been obtained from space-based photometric missions and the accuracy of the resulting frequencies motivate a careful consideration of the accuracy of computed oscillation frequencies of stellar models, when applied as diagnostics of the model properties. Aims.

A Red Giants’ Toy Story. II. Understanding the Red-giant Branch Bump
The Astrophysical Journal, 2023 The Red-Giant Branch Bump (RGBB) is one of the most noteworthy features in the red-giant luminosity function of stellar clusters. It is caused by the passage of the hydrogen-burning shell through the composition discontinuity left at the point of the ...
