Period spacings in red giants; III. Coupling factors of mixed modes
B. Mosser, C. Pinçon, K. Belkacem +2
The power of asteroseismology relies on the capability of global oscillations to infer the stellar structure. For evolved stars, we benefit from unique information directly carried…
A model for stealth coronal mass ejections
B. J. Lynch, S. Masson, Y. Li +4
Stealth coronal mass ejections (CMEs) are events in which there are almost no observable signatures of the CME eruption in the low corona but often a well-resolved slow flux rope C…
A Distant Mirror: Solar Oscillations Observed on Neptune by the Kepler K2 Mission
P. Gaulme, J. F. Rowe, T. R. Bedding +24
Starting in December 2014, Kepler K2 observed Neptune continuously for 49 days at a 1-minute cadence. The goals consisted of studying its atmospheric dynamics (Simon et al. 2016),…
Halpha Doppler shifts in a tornado in the solar corona
B. Schmieder, P. Mein, N. Mein +3
High resolution movies in 193 A from the Atmospheric Imaging Assembly (AIA) on the Solar Dynamic Observatory SDO show apparent rotation in the leg of a prominence observed during a…
Standing on the shoulders of Dwarfs: the Kepler asteroseismic LEGACY sample II - radii, masses, and ages
Victor Silva Aguirre, Mikkel N. Lund, H. M. Antia +21
We use asteroseismic data from the Kepler satellite to determine fundamental stellar properties of the 66 main-sequence targets observed for at least one full year by the mission.…
The K2 Galactic Archaeology Program Data Release 1: Asteroseismic results from Campaign 1
D. Stello, J. Zinn, Y. Elsworth +11
NASA's K2 mission is observing tens of thousands of stars along the ecliptic, providing data suitable for large scale asteroseismic analyses to inform galactic archaeology studies.…
