TL;DR: In this article, the detailed abundances of 23 chemical elements in nine bright red giant branch stars in the Carina dwarf spheroidal galaxy are presented based on high-resolution spectra gathered at the Very Large Telescope (VLT) and Magellan telescopes.

TL;DR: In this article, a critical review of the existing sunspot models and an overview of numerical methods employed to model wave propagation through model sunspots is provided, along with a helioseismic analysis of the sunspot in Active Region 9787 and address the serious inconsistencies uncovered by Gizon et al.

TL;DR: In this paper, various methods of helioseismology are used to study the subsurface properties of the sunspot in NOAA Active Region 9787, which was chosen because it is axisymmetric, shows little evolution during 20−28 January 2002, and was observed continuously by the MDI/SOHO instrument.

TL;DR: In this article, the first clear detections of solar-like oscillations in the cluster red giants were obtained from the first 34 days of science data from the Kepler Mission for the open cluster NGC 6819, one of four clusters in the field of view.
