Oscillations of red giants observed by Kepler

Listed in IVOA Registry (Virtual Observatory)

There are now more than 22 months of long-cadence data available for thousands of red giants observed with the Kepler space mission.

Description

Consequently, we are able to clearly resolve fine details in their oscillation spectra and see many components of the mixed modes that probe the stellar core. We report for the first time a parametric fit to the pattern of the l=1 mixed modes in red giants, which is a powerful tool to identify gravity-dominated mixed modes.

With these modes, which share the characteristics of pressure and gravity modes, we are able to probe directly the helium core and the surrounding shell where hydrogen is burning.
